This can be used to perform denial of service against any system which processes public keys, certificate requests or certificates. This includes TLS clients and TLS servers with client authentication enabled. This issue was reported to OpenSSL by Joseph Barr-Pixton. (CVE-2015-1788) [Andy Polyakov] *) Exploitable out-of-bounds read in X509_cmp_time X509_cmp_time does not properly check the length of the ASN1_TIME string and can read a few bytes out of bounds. In addition, X509_cmp_time accepts an arbitrary number of fractional seconds in the time string. An attacker can use this to craft malformed certificates and CRLs of various sizes and potentially cause a segmentation fault, resulting in a DoS on applications that verify certificates or CRLs. TLS clients that verify CRLs are affected. TLS clients and servers with client authentication enabled may be affected if they use custom verification callbacks. This issue was reported to OpenSSL by Robert Swiecki (Google), and independently by Hanno Böck. (CVE-2015-1789) [Emilia Käsper] *) PKCS7 crash with missing EnvelopedContent The PKCS#7 parsing code does not handle missing inner EncryptedContent correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with missing content and trigger a NULL pointer dereference on parsing. Applications that decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected. This issue was reported to OpenSSL by Michal Zalewski (Google). (CVE-2015-1790) [Emilia Käsper] *) CMS verify infinite loop with unknown hash function When verifying a signedData message the CMS code can enter an infinite loop if presented with an unknown hash function OID. This can be used to perform denial of service against any system which verifies signedData messages using the CMS code. This issue was reported to OpenSSL by Johannes Bauer. (CVE-2015-1792) [Stephen Henson] *) Race condition handling NewSessionTicket If a NewSessionTicket is received by a multi-threaded client when attempting to reuse a previous ticket then a race condition can occur potentially leading to a double free of the ticket data. (CVE-2015-1791) [Matt Caswell] Changes between 0.9.8ze and 0.9.8zf [19 Mar 2015] *) Segmentation fault in ASN1_TYPE_cmp fix The function ASN1_TYPE_cmp will crash with an invalid read if an attempt is made to compare ASN.1 boolean types. Since ASN1_TYPE_cmp is used to check certificate signature algorithm consistency this can be used to crash any certificate verification operation and exploited in a DoS attack. Any application which performs certificate verification is vulnerable including OpenSSL clients and servers which enable client authentication. (CVE-2015-0286) [Stephen Henson] *) ASN.1 structure reuse memory corruption fix Reusing a structure in ASN.1 parsing may allow an attacker to cause memory corruption via an invalid write. Such reuse is and has been strongly discouraged and is believed to be rare. Applications that parse structures containing CHOICE or ANY DEFINED BY components may be affected. Certificate parsing (d2i_X509 and related functions) are however not affected. OpenSSL clients and servers are not affected. (CVE-2015-0287) [Stephen Henson] *) PKCS7 NULL pointer dereferences fix The PKCS#7 parsing code does not handle missing outer ContentInfo correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs with missing content and trigger a NULL pointer dereference on parsing. Applications that verify PKCS#7 signatures, decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected. This issue was reported to OpenSSL by Michal Zalewski (Google). (CVE-2015-0289) [Emilia Käsper] *) DoS via reachable assert in SSLv2 servers fix A malicious client can trigger an OPENSSL_assert (i.e., an abort) in servers that both support SSLv2 and enable export cipher suites by sending a specially crafted SSLv2 CLIENT-MASTER-KEY message. This issue was discovered by Sean Burford (Google) and Emilia Käsper (OpenSSL development team). (CVE-2015-0293) [Emilia Käsper] *) Use After Free following d2i_ECPrivatekey error fix A malformed EC private key file consumed via the d2i_ECPrivateKey function could cause a use after free condition. This, in turn, could cause a double free in several private key parsing functions (such as d2i_PrivateKey or EVP_PKCS82PKEY) and could lead to a DoS attack or memory corruption for applications that receive EC private keys from untrusted sources. This scenario is considered rare. This issue was discovered by the BoringSSL project and fixed in their commit 517073cd4b. (CVE-2015-0209) [Matt Caswell] *) X509_to_X509_REQ NULL pointer deref fix The function X509_to_X509_REQ will crash with a NULL pointer dereference if the certificate key is invalid. This function is rarely used in practice. This issue was discovered by Brian Carpenter. (CVE-2015-0288) [Stephen Henson] *) Removed the export and SSLv2 ciphers from the DEFAULT ciphers [Kurt Roeckx] Changes between 0.9.8zd and 0.9.8ze [15 Jan 2015] *) Build fixes for the Windows and OpenVMS platforms [Matt Caswell and Richard Levitte] Changes between 0.9.8zc and 0.9.8zd [8 Jan 2015] *) Fix DTLS segmentation fault in dtls1_get_record. A carefully crafted DTLS message can cause a segmentation fault in OpenSSL due to a NULL pointer dereference. This could lead to a Denial Of Service attack. Thanks to Markus Stenberg of Cisco Systems, Inc. for reporting this issue. (CVE-2014-3571) [Steve Henson] *) Fix issue where no-ssl3 configuration sets method to NULL. When openssl is built with the no-ssl3 option and a SSL v3 ClientHello is received the ssl method would be set to NULL which could later result in a NULL pointer dereference. Thanks to Frank Schmirler for reporting this issue. (CVE-2014-3569) [Kurt Roeckx] *) Abort handshake if server key exchange message is omitted for ephemeral ECDH ciphersuites. Thanks to Karthikeyan Bhargavan of the PROSECCO team at INRIA for reporting this issue. (CVE-2014-3572) [Steve Henson] *) Remove non-export ephemeral RSA code on client and server. This code violated the TLS standard by allowing the use of temporary RSA keys in non-export ciphersuites and could be used by a server to effectively downgrade the RSA key length used to a value smaller than the server certificate. Thanks for Karthikeyan Bhargavan of the PROSECCO team at INRIA or reporting this issue. (CVE-2015-0204) [Steve Henson] *) Fix various certificate fingerprint issues. By using non-DER or invalid encodings outside the signed portion of a certificate the fingerprint can be changed without breaking the signature. Although no details of the signed portion of the certificate can be changed this can cause problems with some applications: e.g. those using the certificate fingerprint for blacklists. 1. Reject signatures with non zero unused bits. If the BIT STRING containing the signature has non zero unused bits reject the signature. All current signature algorithms require zero unused bits. 2. Check certificate algorithm consistency. Check the AlgorithmIdentifier inside TBS matches the one in the certificate signature. NB: this will result in signature failure errors for some broken certificates. Thanks to Konrad Kraszewski from Google for reporting this issue. 3. Check DSA/ECDSA signatures use DER. Reencode DSA/ECDSA signatures and compare with the original received signature. Return an error if there is a mismatch. This will reject various cases including garbage after signature (thanks to Antti Karjalainen and Tuomo Untinen from the Codenomicon CROSS program for discovering this case) and use of BER or invalid ASN.1 INTEGERs (negative or with leading zeroes). Further analysis was conducted and fixes were developed by Stephen Henson of the OpenSSL core team. (CVE-2014-8275) [Steve Henson] *) Correct Bignum squaring. Bignum squaring (BN_sqr) may produce incorrect results on some platforms, including x86_64. This bug occurs at random with a very low probability, and is not known to be exploitable in any way, though its exact impact is difficult to determine. Thanks to Pieter Wuille (Blockstream) who reported this issue and also suggested an initial fix. Further analysis was conducted by the OpenSSL development team and Adam Langley of Google. The final fix was developed by Andy Polyakov of the OpenSSL core team. (CVE-2014-3570) [Andy Polyakov] Changes between 0.9.8zb and 0.9.8zc [15 Oct 2014] *) Session Ticket Memory Leak. When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. By sending a large number of invalid session tickets an attacker could exploit this issue in a Denial Of Service attack. (CVE-2014-3567) [Steve Henson] *) Build option no-ssl3 is incomplete. When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. (CVE-2014-3568) [Akamai and the OpenSSL team] *) Add support for TLS_FALLBACK_SCSV. Client applications doing fallback retries should call SSL_set_mode(s, SSL_MODE_SEND_FALLBACK_SCSV). (CVE-2014-3566) [Adam Langley, Bodo Moeller] *) Add additional DigestInfo checks. Reencode DigestInto in DER and check against the original when verifying RSA signature: this will reject any improperly encoded DigestInfo structures. Note: this is a precautionary measure and no attacks are currently known. [Steve Henson] Changes between 0.9.8za and 0.9.8zb [6 Aug 2014] *) OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject to a denial of service attack. A malicious server can crash the client with a null pointer dereference (read) by specifying an anonymous (EC)DH ciphersuite and sending carefully crafted handshake messages. Thanks to Felix Gröbert (Google) for discovering and researching this issue. (CVE-2014-3510) [Emilia Käsper] *) By sending carefully crafted DTLS packets an attacker could cause openssl to leak memory. This can be exploited through a Denial of Service attack. Thanks to Adam Langley for discovering and researching this issue. (CVE-2014-3507) [Adam Langley] *) An attacker can force openssl to consume large amounts of memory whilst processing DTLS handshake messages. This can be exploited through a Denial of Service attack. Thanks to Adam Langley for discovering and researching this issue. (CVE-2014-3506) [Adam Langley] *) An attacker can force an error condition which causes openssl to crash whilst processing DTLS packets due to memory being freed twice. This can be exploited through a Denial of Service attack. Thanks to Adam Langley and Wan-Teh Chang for discovering and researching this issue. (CVE-2014-3505) [Adam Langley] *) A flaw in OBJ_obj2txt may cause pretty printing functions such as X509_name_oneline, X509_name_print_ex et al. to leak some information from the stack. Applications may be affected if they echo pretty printing output to the attacker. Thanks to Ivan Fratric (Google) for discovering this issue. (CVE-2014-3508) [Emilia Käsper, and Steve Henson] *) Fix ec_GFp_simple_points_make_affine (thus, EC_POINTs_mul etc.) for corner cases. (Certain input points at infinity could lead to bogus results, with non-infinity inputs mapped to infinity too.) [Bodo Moeller] Changes between 0.9.8y and 0.9.8za [5 Jun 2014] *) Fix for SSL/TLS MITM flaw. An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and researching this issue. (CVE-2014-0224) [KIKUCHI Masashi, Steve Henson] *) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an OpenSSL DTLS client the code can be made to recurse eventually crashing in a DoS attack. Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue. (CVE-2014-0221) [Imre Rad, Steve Henson] *) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can be triggered by sending invalid DTLS fragments to an OpenSSL DTLS client or server. This is potentially exploitable to run arbitrary code on a vulnerable client or server. Thanks to Jüri Aedla for reporting this issue. (CVE-2014-0195) [Jüri Aedla, Steve Henson] *) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites are subject to a denial of service attack. Thanks to Felix Gröbert and Ivan Fratric at Google for discovering this issue. (CVE-2014-3470) [Felix Gröbert, Ivan Fratric, Steve Henson] *) Fix for the attack described in the paper "Recovering OpenSSL ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack" by Yuval Yarom and Naomi Benger. Details can be obtained from: http://eprint.iacr.org/2014/140 Thanks to Yuval Yarom and Naomi Benger for discovering this flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076) [Yuval Yarom and Naomi Benger] Thanks to mancha for backporting the fix to the 0.9.8 branch. *) Fix handling of warning-level alerts in SSL23 client mode so they don't cause client-side termination (eg. on SNI unrecognized_name warnings). Add client and server support for six additional alerts per RFC 6066 and RFC 4279. [mancha] *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which avoids preferring ECDHE-ECDSA ciphers when the client appears to be Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing 10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer. [Rob Stradling, Adam Langley] Changes between 0.9.8x and 0.9.8y [5 Feb 2013] *) Make the decoding of SSLv3, TLS and DTLS CBC records constant time. This addresses the flaw in CBC record processing discovered by Nadhem Alfardan and Kenny Paterson. Details of this attack can be found at: http://www.isg.rhul.ac.uk/tls/ Thanks go to Nadhem Alfardan and Kenny Paterson of the Information Security Group at Royal Holloway, University of London (www.isg.rhul.ac.uk) for discovering this flaw and Adam Langley and Emilia Käsper for the initial patch. (CVE-2013-0169) [Emilia Käsper, Adam Langley, Ben Laurie, Andy Polyakov, Steve Henson] *) Return an error when checking OCSP signatures when key is NULL. This fixes a DoS attack. (CVE-2013-0166) [Steve Henson] *) Call OCSP Stapling callback after ciphersuite has been chosen, so the right response is stapled. Also change SSL_get_certificate() so it returns the certificate actually sent. See http://rt.openssl.org/Ticket/Display.html?id=2836. (This is a backport) [Rob Stradling ] *) Fix possible deadlock when decoding public keys. [Steve Henson] Changes between 0.9.8w and 0.9.8x [10 May 2012] *) Sanity check record length before skipping explicit IV in DTLS to fix DoS attack. Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic fuzzing as a service testing platform. (CVE-2012-2333) [Steve Henson] *) Initialise tkeylen properly when encrypting CMS messages. Thanks to Solar Designer of Openwall for reporting this issue. [Steve Henson] Changes between 0.9.8v and 0.9.8w [23 Apr 2012] *) The fix for CVE-2012-2110 did not take into account that the 'len' argument to BUF_MEM_grow and BUF_MEM_grow_clean is an int in OpenSSL 0.9.8, making it still vulnerable. Fix by rejecting negative len parameter. (CVE-2012-2131) [Tomas Hoger ] Changes between 0.9.8u and 0.9.8v [19 Apr 2012] *) Check for potentially exploitable overflows in asn1_d2i_read_bio BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer in CRYPTO_realloc_clean. Thanks to Tavis Ormandy, Google Security Team, for discovering this issue and to Adam Langley for fixing it. (CVE-2012-2110) [Adam Langley (Google), Tavis Ormandy, Google Security Team] Changes between 0.9.8t and 0.9.8u [12 Mar 2012] *) Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness in CMS and PKCS7 code. When RSA decryption fails use a random key for content decryption and always return the same error. Note: this attack needs on average 2^20 messages so it only affects automated senders. The old behaviour can be reenabled in the CMS code by setting the CMS_DEBUG_DECRYPT flag: this is useful for debugging and testing where an MMA defence is not necessary. Thanks to Ivan Nestlerode for discovering this issue. (CVE-2012-0884) [Steve Henson] *) Fix CVE-2011-4619: make sure we really are receiving a client hello before rejecting multiple SGC restarts. Thanks to Ivan Nestlerode for discovering this bug. [Steve Henson] Changes between 0.9.8s and 0.9.8t [18 Jan 2012] *) Fix for DTLS DoS issue introduced by fix for CVE-2011-4109. Thanks to Antonio Martin, Enterprise Secure Access Research and Development, Cisco Systems, Inc. for discovering this bug and preparing a fix. (CVE-2012-0050) [Antonio Martin] Changes between 0.9.8r and 0.9.8s [4 Jan 2012] *) Nadhem Alfardan and Kenny Paterson have discovered an extension of the Vaudenay padding oracle attack on CBC mode encryption which enables an efficient plaintext recovery attack against the OpenSSL implementation of DTLS. Their attack exploits timing differences arising during decryption processing. A research paper describing this attack can be found at: http://www.isg.rhul.ac.uk/~kp/dtls.pdf Thanks go to Nadhem Alfardan and Kenny Paterson of the Information Security Group at Royal Holloway, University of London (www.isg.rhul.ac.uk) for discovering this flaw and to Robin Seggelmann and Michael Tuexen for preparing the fix. (CVE-2011-4108) [Robin Seggelmann, Michael Tuexen] *) Stop policy check failure freeing same buffer twice. (CVE-2011-4109) [Ben Laurie, Kasper ] *) Clear bytes used for block padding of SSL 3.0 records. (CVE-2011-4576) [Adam Langley (Google)] *) Only allow one SGC handshake restart for SSL/TLS. Thanks to George Kadianakis for discovering this issue and Adam Langley for preparing the fix. (CVE-2011-4619) [Adam Langley (Google)] *) Prevent malformed RFC3779 data triggering an assertion failure. Thanks to Andrew Chi, BBN Technologies, for discovering the flaw and Rob Austein for fixing it. (CVE-2011-4577) [Rob Austein ] *) Fix ssl_ciph.c set-up race. [Adam Langley (Google)] *) Fix spurious failures in ecdsatest.c. [Emilia Käsper (Google)] *) Fix the BIO_f_buffer() implementation (which was mixing different interpretations of the '..._len' fields). [Adam Langley (Google)] *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent threads won't reuse the same blinding coefficients. This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING lock to call BN_BLINDING_invert_ex, and avoids one use of BN_BLINDING_update for each BN_BLINDING structure (previously, the last update always remained unused). [Emilia Käsper (Google)] *) Fix SSL memory handling for (EC)DH ciphersuites, in particular for multi-threaded use of ECDH. [Adam Langley (Google)] *) Fix x509_name_ex_d2i memory leak on bad inputs. [Bodo Moeller] *) Add protection against ECDSA timing attacks as mentioned in the paper by Billy Bob Brumley and Nicola Tuveri, see: http://eprint.iacr.org/2011/232.pdf [Billy Bob Brumley and Nicola Tuveri] Changes between 0.9.8q and 0.9.8r [8 Feb 2011] *) Fix parsing of OCSP stapling ClientHello extension. CVE-2011-0014 [Neel Mehta, Adam Langley, Bodo Moeller (Google)] *) Fix bug in string printing code: if *any* escaping is enabled we must escape the escape character (backslash) or the resulting string is ambiguous. [Steve Henson] Changes between 0.9.8p and 0.9.8q [2 Dec 2010] *) Disable code workaround for ancient and obsolete Netscape browsers and servers: an attacker can use it in a ciphersuite downgrade attack. Thanks to Martin Rex for discovering this bug. CVE-2010-4180 [Steve Henson] *) Fixed J-PAKE implementation error, originally discovered by Sebastien Martini, further info and confirmation from Stefan Arentz and Feng Hao. Note that this fix is a security fix. CVE-2010-4252 [Ben Laurie] Changes between 0.9.8o and 0.9.8p [16 Nov 2010] *) Fix extension code to avoid race conditions which can result in a buffer overrun vulnerability: resumed sessions must not be modified as they can be shared by multiple threads. CVE-2010-3864 [Steve Henson] *) Fix for double free bug in ssl/s3_clnt.c CVE-2010-2939 [Steve Henson] *) Don't reencode certificate when calculating signature: cache and use the original encoding instead. This makes signature verification of some broken encodings work correctly. [Steve Henson] *) ec2_GF2m_simple_mul bugfix: compute correct result if the output EC_POINT is also one of the inputs. [Emilia Käsper (Google)] *) Don't repeatedly append PBE algorithms to table if they already exist. Sort table on each new add. This effectively makes the table read only after all algorithms are added and subsequent calls to PKCS12_pbe_add etc are non-op. [Steve Henson] Changes between 0.9.8n and 0.9.8o [01 Jun 2010] [NB: OpenSSL 0.9.8o and later 0.9.8 patch levels were released after OpenSSL 1.0.0.] *) Correct a typo in the CMS ASN1 module which can result in invalid memory access or freeing data twice (CVE-2010-0742) [Steve Henson, Ronald Moesbergen ] *) Add SHA2 algorithms to SSL_library_init(). SHA2 is becoming far more common in certificates and some applications which only call SSL_library_init and not OpenSSL_add_all_algorithms() will fail. [Steve Henson] *) VMS fixes: Reduce copying into .apps and .test in makevms.com Don't try to use blank CA certificate in CA.com Allow use of C files from original directories in maketests.com [Steven M. Schweda" ] Changes between 0.9.8m and 0.9.8n [24 Mar 2010] *) When rejecting SSL/TLS records due to an incorrect version number, never update s->server with a new major version number. As of - OpenSSL 0.9.8m if 'short' is a 16-bit type, - OpenSSL 0.9.8f if 'short' is longer than 16 bits, the previous behavior could result in a read attempt at NULL when receiving specific incorrect SSL/TLS records once record payload protection is active. (CVE-2010-0740) [Bodo Moeller, Adam Langley ] *) Fix for CVE-2010-0433 where some kerberos enabled versions of OpenSSL could be crashed if the relevant tables were not present (e.g. chrooted). [Tomas Hoger ] Changes between 0.9.8l and 0.9.8m [25 Feb 2010] *) Always check bn_wexpend() return values for failure. (CVE-2009-3245) [Martin Olsson, Neel Mehta] *) Fix X509_STORE locking: Every 'objs' access requires a lock (to accommodate for stack sorting, always a write lock!). [Bodo Moeller] *) On some versions of WIN32 Heap32Next is very slow. This can cause excessive delays in the RAND_poll(): over a minute. As a workaround include a time check in the inner Heap32Next loop too. [Steve Henson] *) The code that handled flushing of data in SSL/TLS originally used the BIO_CTRL_INFO ctrl to see if any data was pending first. This caused the problem outlined in PR#1949. The fix suggested there however can trigger problems with buggy BIO_CTRL_WPENDING (e.g. some versions of Apache). So instead simplify the code to flush unconditionally. This should be fine since flushing with no data to flush is a no op. [Steve Henson] *) Handle TLS versions 2.0 and later properly and correctly use the highest version of TLS/SSL supported. Although TLS >= 2.0 is some way off ancient servers have a habit of sticking around for a while... [Steve Henson] *) Modify compression code so it frees up structures without using the ex_data callbacks. This works around a problem where some applications call CRYPTO_cleanup_all_ex_data() before application exit (e.g. when restarting) then use compression (e.g. SSL with compression) later. This results in significant per-connection memory leaks and has caused some security issues including CVE-2008-1678 and CVE-2009-4355. [Steve Henson] *) Constify crypto/cast (i.e., ): a CAST_KEY doesn't change when encrypting or decrypting. [Bodo Moeller] *) Add option SSL_OP_LEGACY_SERVER_CONNECT which will allow clients to connect and renegotiate with servers which do not support RI. Until RI is more widely deployed this option is enabled by default. [Steve Henson] *) Add "missing" ssl ctrls to clear options and mode. [Steve Henson] *) If client attempts to renegotiate and doesn't support RI respond with a no_renegotiation alert as required by RFC5746. Some renegotiating TLS clients will continue a connection gracefully when they receive the alert. Unfortunately OpenSSL mishandled this alert and would hang waiting for a server hello which it will never receive. Now we treat a received no_renegotiation alert as a fatal error. This is because applications requesting a renegotiation might well expect it to succeed and would have no code in place to handle the server denying it so the only safe thing to do is to terminate the connection. [Steve Henson] *) Add ctrl macro SSL_get_secure_renegotiation_support() which returns 1 if peer supports secure renegotiation and 0 otherwise. Print out peer renegotiation support in s_client/s_server. [Steve Henson] *) Replace the highly broken and deprecated SPKAC certification method with the updated NID creation version. This should correctly handle UTF8. [Steve Henson] *) Implement RFC5746. Re-enable renegotiation but require the extension as needed. Unfortunately, SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION turns out to be a bad idea. It has been replaced by SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION which can be set with SSL_CTX_set_options(). This is really not recommended unless you know what you are doing. [Eric Rescorla , Ben Laurie, Steve Henson] *) Fixes to stateless session resumption handling. Use initial_ctx when issuing and attempting to decrypt tickets in case it has changed during servername handling. Use a non-zero length session ID when attempting stateless session resumption: this makes it possible to determine if a resumption has occurred immediately after receiving server hello (several places in OpenSSL subtly assume this) instead of later in the handshake. [Steve Henson] *) The functions ENGINE_ctrl(), OPENSSL_isservice(), CMS_get1_RecipientRequest() and RAND_bytes() can return <=0 on error fixes for a few places where the return code is not checked correctly. [Julia Lawall ] *) Add --strict-warnings option to Configure script to include devteam warnings in other configurations. [Steve Henson] *) Add support for --libdir option and LIBDIR variable in makefiles. This makes it possible to install openssl libraries in locations which have names other than "lib", for example "/usr/lib64" which some systems need. [Steve Henson, based on patch from Jeremy Utley] *) Don't allow the use of leading 0x80 in OIDs. This is a violation of X690 8.9.12 and can produce some misleading textual output of OIDs. [Steve Henson, reported by Dan Kaminsky] *) Delete MD2 from algorithm tables. This follows the recommendation in several standards that it is not used in new applications due to several cryptographic weaknesses. For binary compatibility reasons the MD2 API is still compiled in by default. [Steve Henson] *) Add compression id to {d2i,i2d}_SSL_SESSION so it is correctly saved and restored. [Steve Henson] *) Rename uni2asc and asc2uni functions to OPENSSL_uni2asc and OPENSSL_asc2uni conditionally on Netware platforms to avoid a name clash. [Guenter ] *) Fix the server certificate chain building code to use X509_verify_cert(), it used to have an ad-hoc builder which was unable to cope with anything other than a simple chain. [David Woodhouse , Steve Henson] *) Don't check self signed certificate signatures in X509_verify_cert() by default (a flag can override this): it just wastes time without adding any security. As a useful side effect self signed root CAs with non-FIPS digests are now usable in FIPS mode. [Steve Henson] *) In dtls1_process_out_of_seq_message() the check if the current message is already buffered was missing. For every new message was memory allocated, allowing an attacker to perform an denial of service attack with sending out of seq handshake messages until there is no memory left. Additionally every future messege was buffered, even if the sequence number made no sense and would be part of another handshake. So only messages with sequence numbers less than 10 in advance will be buffered. (CVE-2009-1378) [Robin Seggelmann, discovered by Daniel Mentz] *) Records are buffered if they arrive with a future epoch to be processed after finishing the corresponding handshake. There is currently no limitation to this buffer allowing an attacker to perform a DOS attack with sending records with future epochs until there is no memory left. This patch adds the pqueue_size() function to detemine the size of a buffer and limits the record buffer to 100 entries. (CVE-2009-1377) [Robin Seggelmann, discovered by Daniel Mentz] *) Keep a copy of frag->msg_header.frag_len so it can be used after the parent structure is freed. (CVE-2009-1379) [Daniel Mentz] *) Handle non-blocking I/O properly in SSL_shutdown() call. [Darryl Miles ] *) Add 2.5.4.* OIDs [Ilya O. ] Changes between 0.9.8k and 0.9.8l [5 Nov 2009] *) Disable renegotiation completely - this fixes a severe security problem (CVE-2009-3555) at the cost of breaking all renegotiation. Renegotiation can be re-enabled by setting SSL3_FLAGS_ALLOW_UNSAFE_LEGACY_RENEGOTIATION in s3->flags at run-time. This is really not recommended unless you know what you're doing. [Ben Laurie] Changes between 0.9.8j and 0.9.8k [25 Mar 2009] *) Don't set val to NULL when freeing up structures, it is freed up by underlying code. If sizeof(void *) > sizeof(long) this can result in zeroing past the valid field. (CVE-2009-0789) [Paolo Ganci ] *) Fix bug where return value of CMS_SignerInfo_verify_content() was not checked correctly. This would allow some invalid signed attributes to appear to verify correctly. (CVE-2009-0591) [Ivan Nestlerode ] *) Reject UniversalString and BMPString types with invalid lengths. This prevents a crash in ASN1_STRING_print_ex() which assumes the strings have a legal length. (CVE-2009-0590) [Steve Henson] *) Set S/MIME signing as the default purpose rather than setting it unconditionally. This allows applications to override it at the store level. [Steve Henson] *) Permit restricted recursion of ASN1 strings. This is needed in practice to handle some structures. [Steve Henson] *) Improve efficiency of mem_gets: don't search whole buffer each time for a '\n' [Jeremy Shapiro ] *) New -hex option for openssl rand. [Matthieu Herrb] *) Print out UTF8String and NumericString when parsing ASN1. [Steve Henson] *) Support NumericString type for name components. [Steve Henson] *) Allow CC in the environment to override the automatically chosen compiler. Note that nothing is done to ensure flags work with the chosen compiler. [Ben Laurie] Changes between 0.9.8i and 0.9.8j [07 Jan 2009] *) Properly check EVP_VerifyFinal() and similar return values (CVE-2008-5077). [Ben Laurie, Bodo Moeller, Google Security Team] *) Enable TLS extensions by default. [Ben Laurie] *) Allow the CHIL engine to be loaded, whether the application is multithreaded or not. (This does not release the developer from the obligation to set up the dynamic locking callbacks.) [Sander Temme ] *) Use correct exit code if there is an error in dgst command. [Steve Henson; problem pointed out by Roland Dirlewanger] *) Tweak Configure so that you need to say "experimental-jpake" to enable JPAKE, and need to use -DOPENSSL_EXPERIMENTAL_JPAKE in applications. [Bodo Moeller] *) Add experimental JPAKE support, including demo authentication in s_client and s_server. [Ben Laurie] *) Set the comparison function in v3_addr_canonize(). [Rob Austein ] *) Add support for XMPP STARTTLS in s_client. [Philip Paeps ] *) Change the server-side SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG behavior to ensure that even with this option, only ciphersuites in the server's preference list will be accepted. (Note that the option applies only when resuming a session, so the earlier behavior was just about the algorithm choice for symmetric cryptography.) [Bodo Moeller] Changes between 0.9.8h and 0.9.8i [15 Sep 2008] *) Fix NULL pointer dereference if a DTLS server received ChangeCipherSpec as first record (CVE-2009-1386). [PR #1679] *) Fix a state transitition in s3_srvr.c and d1_srvr.c (was using SSL3_ST_CW_CLNT_HELLO_B, should be ..._ST_SW_SRVR_...). [Nagendra Modadugu] *) The fix in 0.9.8c that supposedly got rid of unsafe double-checked locking was incomplete for RSA blinding, addressing just one layer of what turns out to have been doubly unsafe triple-checked locking. So now fix this for real by retiring the MONT_HELPER macro in crypto/rsa/rsa_eay.c. [Bodo Moeller; problem pointed out by Marius Schilder] *) Various precautionary measures: - Avoid size_t integer overflow in HASH_UPDATE (md32_common.h). - Avoid a buffer overflow in d2i_SSL_SESSION() (ssl_asn1.c). (NB: This would require knowledge of the secret session ticket key to exploit, in which case you'd be SOL either way.) - Change bn_nist.c so that it will properly handle input BIGNUMs outside the expected range. - Enforce the 'num' check in BN_div() (bn_div.c) for non-BN_DEBUG builds. [Neel Mehta, Bodo Moeller] *) Allow engines to be "soft loaded" - i.e. optionally don't die if the load fails. Useful for distros. [Ben Laurie and the FreeBSD team] *) Add support for Local Machine Keyset attribute in PKCS#12 files. [Steve Henson] *) Fix BN_GF2m_mod_arr() top-bit cleanup code. [Huang Ying] *) Expand ENGINE to support engine supplied SSL client certificate functions. This work was sponsored by Logica. [Steve Henson] *) Add CryptoAPI ENGINE to support use of RSA and DSA keys held in Windows keystores. Support for SSL/TLS client authentication too. Not compiled unless enable-capieng specified to Configure. This work was sponsored by Logica. [Steve Henson] *) Fix bug in X509_ATTRIBUTE creation: dont set attribute using ASN1_TYPE_set1 if MBSTRING flag set. This bug would crash certain attribute creation routines such as certifcate requests and PKCS#12 files. [Steve Henson] Changes between 0.9.8g and 0.9.8h [28 May 2008] *) Fix flaw if 'Server Key exchange message' is omitted from a TLS handshake which could lead to a cilent crash as found using the Codenomicon TLS test suite (CVE-2008-1672) [Steve Henson, Mark Cox] *) Fix double free in TLS server name extensions which could lead to a remote crash found by Codenomicon TLS test suite (CVE-2008-0891) [Joe Orton] *) Clear error queue in SSL_CTX_use_certificate_chain_file() Clear the error queue to ensure that error entries left from older function calls do not interfere with the correct operation. [Lutz Jaenicke, Erik de Castro Lopo] *) Remove root CA certificates of commercial CAs: The OpenSSL project does not recommend any specific CA and does not have any policy with respect to including or excluding any CA. Therefore it does not make any sense to ship an arbitrary selection of root CA certificates with the OpenSSL software. [Lutz Jaenicke] *) RSA OAEP patches to fix two separate invalid memory reads. The first one involves inputs when 'lzero' is greater than 'SHA_DIGEST_LENGTH' (it would read about SHA_DIGEST_LENGTH bytes before the beginning of from). The second one involves inputs where the 'db' section contains nothing but zeroes (there is a one-byte invalid read after the end of 'db'). [Ivan Nestlerode ] *) Partial backport from 0.9.9-dev: Introduce bn_mul_mont (dedicated Montgomery multiplication procedure) as a candidate for BIGNUM assembler implementation. While 0.9.9-dev uses assembler for various architectures, only x86_64 is available by default here in the 0.9.8 branch, and 32-bit x86 is available through a compile-time setting. To try the 32-bit x86 assembler implementation, use Configure option "enable-montasm" (which exists only for this backport). As "enable-montasm" for 32-bit x86 disclaims code stability anyway, in this constellation we activate additional code backported from 0.9.9-dev for further performance improvements, namely BN_from_montgomery_word. (To enable this otherwise, e.g. x86_64, try "-DMONT_FROM_WORD___NON_DEFAULT_0_9_8_BUILD".) [Andy Polyakov (backport partially by Bodo Moeller)] *) Add TLS session ticket callback. This allows an application to set TLS ticket cipher and HMAC keys rather than relying on hardcoded fixed values. This is useful for key rollover for example where several key sets may exist with different names. [Steve Henson] *) Reverse ENGINE-internal logic for caching default ENGINE handles. This was broken until now in 0.9.8 releases, such that the only way a registered ENGINE could be used (assuming it initialises successfully on the host) was to explicitly set it as the default for the relevant algorithms. This is in contradiction with 0.9.7 behaviour and the documentation. With this fix, when an ENGINE is registered into a given algorithm's table of implementations, the 'uptodate' flag is reset so that auto-discovery will be used next time a new context for that algorithm attempts to select an implementation. [Ian Lister (tweaked by Geoff Thorpe)] *) Backport of CMS code to OpenSSL 0.9.8. This differs from the 0.9.9 implemention in the following ways: Lack of EVP_PKEY_ASN1_METHOD means algorithm parameters have to be hard coded. Lack of BER streaming support means one pass streaming processing is only supported if data is detached: setting the streaming flag is ignored for embedded content. CMS support is disabled by default and must be explicitly enabled with the enable-cms configuration option. [Steve Henson] *) Update the GMP engine glue to do direct copies between BIGNUM and mpz_t when openssl and GMP use the same limb size. Otherwise the existing "conversion via a text string export" trick is still used. [Paul Sheer ] *) Zlib compression BIO. This is a filter BIO which compressed and uncompresses any data passed through it. [Steve Henson] *) Add AES_wrap_key() and AES_unwrap_key() functions to implement RFC3394 compatible AES key wrapping. [Steve Henson] *) Add utility functions to handle ASN1 structures. ASN1_STRING_set0(): sets string data without copying. X509_ALGOR_set0() and X509_ALGOR_get0(): set and retrieve X509_ALGOR (AlgorithmIdentifier) data. Attribute function X509at_get0_data_by_OBJ(): retrieves data from an X509_ATTRIBUTE structure optionally checking it occurs only once. ASN1_TYPE_set1(): set and ASN1_TYPE structure copying supplied data. [Steve Henson] *) Fix BN flag handling in RSA_eay_mod_exp() and BN_MONT_CTX_set() to get the expected BN_FLG_CONSTTIME behavior. [Bodo Moeller (Google)] *) Netware support: - fixed wrong usage of ioctlsocket() when build for LIBC BSD sockets - fixed do_tests.pl to run the test suite with CLIB builds too (CLIB_OPT) - added some more tests to do_tests.pl - fixed RunningProcess usage so that it works with newer LIBC NDKs too - removed usage of BN_LLONG for CLIB builds to avoid runtime dependency - added new Configure targets netware-clib-bsdsock, netware-clib-gcc, netware-clib-bsdsock-gcc, netware-libc-bsdsock-gcc - various changes to netware.pl to enable gcc-cross builds on Win32 platform - changed crypto/bio/b_sock.c to work with macro functions (CLIB BSD) - various changes to fix missing prototype warnings - fixed x86nasm.pl to create correct asm files for NASM COFF output - added AES, WHIRLPOOL and CPUID assembler code to build files - added missing AES assembler make rules to mk1mf.pl - fixed order of includes in apps/ocsp.c so that e_os.h settings apply [Guenter Knauf ] *) Implement certificate status request TLS extension defined in RFC3546. A client can set the appropriate parameters and receive the encoded OCSP response via a callback. A server can query the supplied parameters and set the encoded OCSP response in the callback. Add simplified examples to s_client and s_server. [Steve Henson] Changes between 0.9.8f and 0.9.8g [19 Oct 2007] *) Fix various bugs: + Binary incompatibility of ssl_ctx_st structure + DTLS interoperation with non-compliant servers + Don't call get_session_cb() without proposed session + Fix ia64 assembler code [Andy Polyakov, Steve Henson] Changes between 0.9.8e and 0.9.8f [11 Oct 2007] *) DTLS Handshake overhaul. There were longstanding issues with OpenSSL DTLS implementation, which were making it impossible for RFC 4347 compliant client to communicate with OpenSSL server. Unfortunately just fixing these incompatibilities would "cut off" pre-0.9.8f clients. To allow for hassle free upgrade post-0.9.8e server keeps tolerating non RFC compliant syntax. The opposite is not true, 0.9.8f client can not communicate with earlier server. This update even addresses CVE-2007-4995. [Andy Polyakov] *) Changes to avoid need for function casts in OpenSSL: some compilers (gcc 4.2 and later) reject their use. [Kurt Roeckx , Peter Hartley , Steve Henson] *) Add RFC4507 support to OpenSSL. This includes the corrections in RFC4507bis. The encrypted ticket format is an encrypted encoded SSL_SESSION structure, that way new session features are automatically supported. If a client application caches session in an SSL_SESSION structure support is transparent because tickets are now stored in the encoded SSL_SESSION. The SSL_CTX structure automatically generates keys for ticket protection in servers so again support should be possible with no application modification. If a client or server wishes to disable RFC4507 support then the option SSL_OP_NO_TICKET can be set. Add a TLS extension debugging callback to allow the contents of any client or server extensions to be examined. This work was sponsored by Google. [Steve Henson] *) Add initial support for TLS extensions, specifically for the server_name extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now have new members for a host name. The SSL data structure has an additional member SSL_CTX *initial_ctx so that new sessions can be stored in that context to allow for session resumption, even after the SSL has been switched to a new SSL_CTX in reaction to a client's server_name extension. New functions (subject to change): SSL_get_servername() SSL_get_servername_type() SSL_set_SSL_CTX() New CTRL codes and macros (subject to change): SSL_CTRL_SET_TLSEXT_SERVERNAME_CB - SSL_CTX_set_tlsext_servername_callback() SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG - SSL_CTX_set_tlsext_servername_arg() SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() openssl s_client has a new '-servername ...' option. openssl s_server has new options '-servername_host ...', '-cert2 ...', '-key2 ...', '-servername_fatal' (subject to change). This allows testing the HostName extension for a specific single host name ('-cert' and '-key' remain fallbacks for handshakes without HostName negotiation). If the unrecogninzed_name alert has to be sent, this by default is a warning; it becomes fatal with the '-servername_fatal' option. [Peter Sylvester, Remy Allais, Christophe Renou, Steve Henson] *) Add AES and SSE2 assembly language support to VC++ build. [Steve Henson] *) Mitigate attack on final subtraction in Montgomery reduction. [Andy Polyakov] *) Fix crypto/ec/ec_mult.c to work properly with scalars of value 0 (which previously caused an internal error). [Bodo Moeller] *) Squeeze another 10% out of IGE mode when in != out. [Ben Laurie] *) AES IGE mode speedup. [Dean Gaudet (Google)] *) Add the Korean symmetric 128-bit cipher SEED (see http://www.kisa.or.kr/kisa/seed/jsp/seed_eng.jsp) and add SEED ciphersuites from RFC 4162: TLS_RSA_WITH_SEED_CBC_SHA = "SEED-SHA" TLS_DHE_DSS_WITH_SEED_CBC_SHA = "DHE-DSS-SEED-SHA" TLS_DHE_RSA_WITH_SEED_CBC_SHA = "DHE-RSA-SEED-SHA" TLS_DH_anon_WITH_SEED_CBC_SHA = "ADH-SEED-SHA" To minimize changes between patchlevels in the OpenSSL 0.9.8 series, SEED remains excluded from compilation unless OpenSSL is configured with 'enable-seed'. [KISA, Bodo Moeller] *) Mitigate branch prediction attacks, which can be practical if a single processor is shared, allowing a spy process to extract information. For detailed background information, see http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron, J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL and Necessary Software Countermeasures"). The core of the change are new versions BN_div_no_branch() and BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(), respectively, which are slower, but avoid the security-relevant conditional branches. These are automatically called by BN_div() and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one of the input BIGNUMs. Also, BN_is_bit_set() has been changed to remove a conditional branch. BN_FLG_CONSTTIME is the new name for the previous BN_FLG_EXP_CONSTTIME flag, since it now affects more than just modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag in the exponent causes BN_mod_exp_mont() to use the alternative implementation in BN_mod_exp_mont_consttime().) The old name remains as a deprecated alias. Similary, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses constant-time implementations for more than just exponentiation. Here too the old name is kept as a deprecated alias. BN_BLINDING_new() will now use BN_dup() for the modulus so that the BN_BLINDING structure gets an independent copy of the modulus. This means that the previous "BIGNUM *m" argument to BN_BLINDING_new() and to BN_BLINDING_create_param() now essentially becomes "const BIGNUM *m", although we can't actually change this in the header file before 0.9.9. It allows RSA_setup_blinding() to use BN_with_flags() on the modulus to enable BN_FLG_CONSTTIME. [Matthew D Wood (Intel Corp)] *) In the SSL/TLS server implementation, be strict about session ID context matching (which matters if an application uses a single external cache for different purposes). Previously, out-of-context reuse was forbidden only if SSL_VERIFY_PEER was set. This did ensure strict client verification, but meant that, with applications using a single external cache for quite different requirements, clients could circumvent ciphersuite restrictions for a given session ID context by starting a session in a different context. [Bodo Moeller] *) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that a ciphersuite string such as "DEFAULT:RSA" cannot enable authentication-only ciphersuites. [Bodo Moeller] *) Update the SSL_get_shared_ciphers() fix CVE-2006-3738 which was not complete and could lead to a possible single byte overflow (CVE-2007-5135) [Ben Laurie] Changes between 0.9.8d and 0.9.8e [23 Feb 2007] *) Since AES128 and AES256 (and similarly Camellia128 and Camellia256) share a single mask bit in the logic of ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a kludge to work properly if AES128 is available and AES256 isn't (or if Camellia128 is available and Camellia256 isn't). [Victor Duchovni] *) Fix the BIT STRING encoding generated by crypto/ec/ec_asn1.c (within i2d_ECPrivateKey, i2d_ECPKParameters, i2d_ECParameters): When a point or a seed is encoded in a BIT STRING, we need to prevent the removal of trailing zero bits to get the proper DER encoding. (By default, crypto/asn1/a_bitstr.c assumes the case of a NamedBitList, for which trailing 0 bits need to be removed.) [Bodo Moeller] *) Have SSL/TLS server implementation tolerate "mismatched" record protocol version while receiving ClientHello even if the ClientHello is fragmented. (The server can't insist on the particular protocol version it has chosen before the ServerHello message has informed the client about his choice.) [Bodo Moeller] *) Add RFC 3779 support. [Rob Austein for ARIN, Ben Laurie] *) Load error codes if they are not already present instead of using a static variable. This allows them to be cleanly unloaded and reloaded. Improve header file function name parsing. [Steve Henson] *) extend SMTP and IMAP protocol emulation in s_client to use EHLO or CAPABILITY handshake as required by RFCs. [Goetz Babin-Ebell] Changes between 0.9.8c and 0.9.8d [28 Sep 2006] *) Introduce limits to prevent malicious keys being able to cause a denial of service. (CVE-2006-2940) [Steve Henson, Bodo Moeller] *) Fix ASN.1 parsing of certain invalid structures that can result in a denial of service. (CVE-2006-2937) [Steve Henson] *) Fix buffer overflow in SSL_get_shared_ciphers() function. (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team] *) Fix SSL client code which could crash if connecting to a malicious SSLv2 server. (CVE-2006-4343) [Tavis Ormandy and Will Drewry, Google Security Team] *) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites match only those. Before that, "AES256-SHA" would be interpreted as a pattern and match "AES128-SHA" too (since AES128-SHA got the same strength classification in 0.9.7h) as we currently only have a single AES bit in the ciphersuite description bitmap. That change, however, also applied to ciphersuite strings such as "RC4-MD5" that intentionally matched multiple ciphersuites -- namely, SSL 2.0 ciphersuites in addition to the more common ones from SSL 3.0/TLS 1.0. So we change the selection algorithm again: Naming an explicit ciphersuite selects this one ciphersuite, and any other similar ciphersuite (same bitmap) from *other* protocol versions. Thus, "RC4-MD5" again will properly select both the SSL 2.0 ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite. Since SSL 2.0 does not have any ciphersuites for which the 128/256 bit distinction would be relevant, this works for now. The proper fix will be to use different bits for AES128 and AES256, which would have avoided the problems from the beginning; however, bits are scarce, so we can only do this in a new release (not just a patchlevel) when we can change the SSL_CIPHER definition to split the single 'unsigned long mask' bitmap into multiple values to extend the available space. [Bodo Moeller] Changes between 0.9.8b and 0.9.8c [05 Sep 2006] *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher (CVE-2006-4339) [Ben Laurie and Google Security Team] *) Add AES IGE and biIGE modes. [Ben Laurie] *) Change the Unix randomness entropy gathering to use poll() when possible instead of select(), since the latter has some undesirable limitations. [Darryl Miles via Richard Levitte and Bodo Moeller] *) Disable "ECCdraft" ciphersuites more thoroughly. Now special treatment in ssl/ssl_ciph.s makes sure that these ciphersuites cannot be implicitly activated as part of, e.g., the "AES" alias. However, please upgrade to OpenSSL 0.9.9[-dev] for non-experimental use of the ECC ciphersuites to get TLS extension support, which is required for curve and point format negotiation to avoid potential handshake problems. [Bodo Moeller] *) Disable rogue ciphersuites: - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5") - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5") - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5") The latter two were purportedly from draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really appear there. Also deactivate the remaining ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as unofficial, and the ID has long expired. [Bodo Moeller] *) Fix RSA blinding Heisenbug (problems sometimes occured on dual-core machines) and other potential thread-safety issues. [Bodo Moeller] *) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key versions), which is now available for royalty-free use (see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html). Also, add Camellia TLS ciphersuites from RFC 4132. To minimize changes between patchlevels in the OpenSSL 0.9.8 series, Camellia remains excluded from compilation unless OpenSSL is configured with 'enable-camellia'. [NTT] *) Disable the padding bug check when compression is in use. The padding bug check assumes the first packet is of even length, this is not necessarily true if compresssion is enabled and can result in false positives causing handshake failure. The actual bug test is ancient code so it is hoped that implementations will either have fixed it by now or any which still have the bug do not support compression. [Steve Henson] Changes between 0.9.8a and 0.9.8b [04 May 2006] *) When applying a cipher rule check to see if string match is an explicit cipher suite and only match that one cipher suite if it is. [Steve Henson] *) Link in manifests for VC++ if needed. [Austin Ziegler ] *) Update support for ECC-based TLS ciphersuites according to draft-ietf-tls-ecc-12.txt with proposed changes (but without TLS extensions, which are supported starting with the 0.9.9 branch, not in the OpenSSL 0.9.8 branch). [Douglas Stebila] *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support opaque EVP_CIPHER_CTX handling. [Steve Henson] *) Fixes and enhancements to zlib compression code. We now only use "zlib1.dll" and use the default __cdecl calling convention on Win32 to conform with the standards mentioned here: http://www.zlib.net/DLL_FAQ.txt Static zlib linking now works on Windows and the new --with-zlib-include --with-zlib-lib options to Configure can be used to supply the location of the headers and library. Gracefully handle case where zlib library can't be loaded. [Steve Henson] *) Several fixes and enhancements to the OID generation code. The old code sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't handle numbers larger than ULONG_MAX, truncated printing and had a non standard OBJ_obj2txt() behaviour. [Steve Henson] *) Add support for building of engines under engine/ as shared libraries under VC++ build system. [Steve Henson] *) Corrected the numerous bugs in the Win32 path splitter in DSO. Hopefully, we will not see any false combination of paths any more. [Richard Levitte] Changes between 0.9.8 and 0.9.8a [11 Oct 2005] *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING (part of SSL_OP_ALL). This option used to disable the countermeasure against man-in-the-middle protocol-version rollback in the SSL 2.0 server implementation, which is a bad idea. (CVE-2005-2969) [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center for Information Security, National Institute of Advanced Industrial Science and Technology [AIST], Japan)] *) Add two function to clear and return the verify parameter flags. [Steve Henson] *) Keep cipherlists sorted in the source instead of sorting them at runtime, thus removing the need for a lock. [Nils Larsch] *) Avoid some small subgroup attacks in Diffie-Hellman. [Nick Mathewson and Ben Laurie] *) Add functions for well-known primes. [Nick Mathewson] *) Extended Windows CE support. [Satoshi Nakamura and Andy Polyakov] *) Initialize SSL_METHOD structures at compile time instead of during runtime, thus removing the need for a lock. [Steve Henson] *) Make PKCS7_decrypt() work even if no certificate is supplied by attempting to decrypt each encrypted key in turn. Add support to smime utility. [Steve Henson] Changes between 0.9.7h and 0.9.8 [05 Jul 2005] [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after OpenSSL 0.9.8.] *) Add libcrypto.pc and libssl.pc for those who feel they need them. [Richard Levitte] *) Change CA.sh and CA.pl so they don't bundle the CSR and the private key into the same file any more. [Richard Levitte] *) Add initial support for Win64, both IA64 and AMD64/x64 flavors. [Andy Polyakov] *) Add -utf8 command line and config file option to 'ca'. [Stefan and Geoff Thorpe] *) Add attribute functions to EVP_PKEY structure. Modify PKCS12_create() to recognize a CSP name attribute and use it. Make -CSP option work again in pkcs12 utility. [Steve Henson] *) Add new functionality to the bn blinding code: - automatic re-creation of the BN_BLINDING parameters after a fixed number of uses (currently 32) - add new function for parameter creation - introduce flags to control the update behaviour of the BN_BLINDING parameters - hide BN_BLINDING structure Add a second BN_BLINDING slot to the RSA structure to improve performance when a single RSA object is shared among several threads. [Nils Larsch] *) Add support for DTLS. [Nagendra Modadugu and Ben Laurie] *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() [Walter Goulet] *) Remove buggy and incompletet DH cert support from ssl/ssl_rsa.c and ssl/s3_both.c [Nils Larsch] *) Use SHA-1 instead of MD5 as the default digest algorithm for the apps/openssl applications. [Nils Larsch] *) Compile clean with "-Wall -Wmissing-prototypes -Wstrict-prototypes -Wmissing-declarations -Werror". Currently DEBUG_SAFESTACK must also be set. [Ben Laurie] *) Change ./Configure so that certain algorithms can be disabled by default. The new counterpiece to "no-xxx" is "enable-xxx". The patented RC5 and MDC2 algorithms will now be disabled unless "enable-rc5" and "enable-mdc2", respectively, are specified. (IDEA remains enabled despite being patented. This is because IDEA is frequently required for interoperability, and there is no license fee for non-commercial use. As before, "no-idea" can be used to avoid this algorithm.) [Bodo Moeller] *) Add processing of proxy certificates (see RFC 3820). This work was sponsored by KTH (The Royal Institute of Technology in Stockholm) and EGEE (Enabling Grids for E-science in Europe). [Richard Levitte] *) RC4 performance overhaul on modern architectures/implementations, such as Intel P4, IA-64 and AMD64. [Andy Polyakov] *) New utility extract-section.pl. This can be used specify an alternative section number in a pod file instead of having to treat each file as a separate case in Makefile. This can be done by adding two lines to the pod file: =for comment openssl_section:XXX The blank line is mandatory. [Steve Henson] *) New arguments -certform, -keyform and -pass for s_client and s_server to allow alternative format key and certificate files and passphrase sources. [Steve Henson] *) New structure X509_VERIFY_PARAM which combines current verify parameters, update associated structures and add various utility functions. Add new policy related verify parameters, include policy checking in standard verify code. Enhance 'smime' application with extra parameters to support policy checking and print out. [Steve Henson] *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 Nehemiah processors. These extensions support AES encryption in hardware as well as RNG (though RNG support is currently disabled). [Michal Ludvig , with help from Andy Polyakov] *) Deprecate BN_[get|set]_params() functions (they were ignored internally). [Geoff Thorpe] *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. [Andy Polyakov and a number of other people] *) Improved PowerPC platform support. Most notably BIGNUM assembler implementation contributed by IBM. [Suresh Chari, Peter Waltenberg, Andy Polyakov] *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public exponent rather than 'unsigned long'. There is a corresponding change to the new 'rsa_keygen' element of the RSA_METHOD structure. [Jelte Jansen, Geoff Thorpe] *) Functionality for creating the initial serial number file is now moved from CA.pl to the 'ca' utility with a new option -create_serial. (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial number file to 1, which is bound to cause problems. To avoid the problems while respecting compatibility between different 0.9.7 patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in CA.pl for serial number initialization. With the new release 0.9.8, we can fix the problem directly in the 'ca' utility.) [Steve Henson] *) Reduced header interdepencies by declaring more opaque objects in ossl_typ.h. As a consequence, including some headers (eg. engine.h) will give fewer recursive includes, which could break lazy source code - so this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, developers should define this symbol when building and using openssl to ensure they track the recommended behaviour, interfaces, [etc], but backwards-compatible behaviour prevails when this isn't defined. [Geoff Thorpe] *) New function X509_POLICY_NODE_print() which prints out policy nodes. [Steve Henson] *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. This will generate a random key of the appropriate length based on the cipher context. The EVP_CIPHER can provide its own random key generation routine to support keys of a specific form. This is used in the des and 3des routines to generate a key of the correct parity. Update S/MIME code to use new functions and hence generate correct parity DES keys. Add EVP_CHECK_DES_KEY #define to return an error if the key is not valid (weak or incorrect parity). [Steve Henson] *) Add a local set of CRLs that can be used by X509_verify_cert() as well as looking them up. This is useful when the verified structure may contain CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs present unless the new PKCS7_NO_CRL flag is asserted. [Steve Henson] *) Extend ASN1 oid configuration module. It now additionally accepts the syntax: shortName = some long name, 1.2.3.4 [Steve Henson] *) Reimplemented the BN_CTX implementation. There is now no more static limitation on the number of variables it can handle nor the depth of the "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack information can now expand as required, and rather than having a single static array of bignums, BN_CTX now uses a linked-list of such arrays allowing it to expand on demand whilst maintaining the usefulness of BN_CTX's "bundling". [Geoff Thorpe] *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD to allow all RSA operations to function using a single BN_CTX. [Geoff Thorpe] *) Preliminary support for certificate policy evaluation and checking. This is initially intended to pass the tests outlined in "Conformance Testing of Relying Party Client Certificate Path Processing Logic" v1.07. [Steve Henson] *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and remained unused and not that useful. A variety of other little bignum tweaks and fixes have also been made continuing on from the audit (see below). [Geoff Thorpe] *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with associated ASN1, EVP and SSL functions and old ASN1 macros. [Richard Levitte] *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, and this should never fail. So the return value from the use of BN_set_word() (which can fail due to needless expansion) is now deprecated; if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. [Geoff Thorpe] *) BN_CTX_get() should return zero-valued bignums, providing the same initialised value as BN_new(). [Geoff Thorpe, suggested by Ulf Möller] *) Support for inhibitAnyPolicy certificate extension. [Steve Henson] *) An audit of the BIGNUM code is underway, for which debugging code is enabled when BN_DEBUG is defined. This makes stricter enforcements on what is considered valid when processing BIGNUMs, and causes execution to assert() when a problem is discovered. If BN_DEBUG_RAND is defined, further steps are taken to deliberately pollute unused data in BIGNUM structures to try and expose faulty code further on. For now, openssl will (in its default mode of operation) continue to tolerate the inconsistent forms that it has tolerated in the past, but authors and packagers should consider trying openssl and their own applications when compiled with these debugging symbols defined. It will help highlight potential bugs in their own code, and will improve the test coverage for OpenSSL itself. At some point, these tighter rules will become openssl's default to improve maintainability, though the assert()s and other overheads will remain only in debugging configurations. See bn.h for more details. [Geoff Thorpe, Nils Larsch, Ulf Möller] *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure that can only be obtained through BN_CTX_new() (which implicitly initialises it). The presence of this function only made it possible to overwrite an existing structure (and cause memory leaks). [Geoff Thorpe] *) Because of the callback-based approach for implementing LHASH as a template type, lh_insert() adds opaque objects to hash-tables and lh_doall() or lh_doall_arg() are typically used with a destructor callback to clean up those corresponding objects before destroying the hash table (and losing the object pointers). So some over-zealous constifications in LHASH have been relaxed so that lh_insert() does not take (nor store) the objects as "const" and the lh_doall[_arg] callback wrappers are not prototyped to have "const" restrictions on the object pointers they are given (and so aren't required to cast them away any more). [Geoff Thorpe] *) The tmdiff.h API was so ugly and minimal that our own timing utility (speed) prefers to use its own implementation. The two implementations haven't been consolidated as yet (volunteers?) but the tmdiff API has had its object type properly exposed (MS_TM) instead of casting to/from "char *". This may still change yet if someone realises MS_TM and "ms_time_***" aren't necessarily the greatest nomenclatures - but this is what was used internally to the implementation so I've used that for now. [Geoff Thorpe] *) Ensure that deprecated functions do not get compiled when OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of the self-tests were still using deprecated key-generation functions so these have been updated also. [Geoff Thorpe] *) Reorganise PKCS#7 code to separate the digest location functionality into PKCS7_find_digest(), digest addtion into PKCS7_bio_add_digest(). New function PKCS7_set_digest() to set the digest type for PKCS#7 digestedData type. Add additional code to correctly generate the digestedData type and add support for this type in PKCS7 initialization functions. [Steve Henson] *) New function PKCS7_set0_type_other() this initializes a PKCS7 structure of type "other". [Steve Henson] *) Fix prime generation loop in crypto/bn/bn_prime.pl by making sure the loop does correctly stop and breaking ("division by zero") modulus operations are not performed. The (pre-generated) prime table crypto/bn/bn_prime.h was already correct, but it could not be re-generated on some platforms because of the "division by zero" situation in the script. [Ralf S. Engelschall] *) Update support for ECC-based TLS ciphersuites according to draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with SHA-1 now is only used for "small" curves (where the representation of a field element takes up to 24 bytes); for larger curves, the field element resulting from ECDH is directly used as premaster secret. [Douglas Stebila (Sun Microsystems Laboratories)] *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2 curve secp160r1 to the tests. [Douglas Stebila (Sun Microsystems Laboratories)] *) Add the possibility to load symbols globally with DSO. [Götz Babin-Ebell via Richard Levitte] *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better control of the error stack. [Richard Levitte] *) Add support for STORE in ENGINE. [Richard Levitte] *) Add the STORE type. The intention is to provide a common interface to certificate and key stores, be they simple file-based stores, or HSM-type store, or LDAP stores, or... NOTE: The code is currently UNTESTED and isn't really used anywhere. [Richard Levitte] *) Add a generic structure called OPENSSL_ITEM. This can be used to pass a list of arguments to any function as well as provide a way for a function to pass data back to the caller. [Richard Levitte] *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup() works like BUF_strdup() but can be used to duplicate a portion of a string. The copy gets NUL-terminated. BUF_memdup() duplicates a memory area. [Richard Levitte] *) Add the function sk_find_ex() which works like sk_find(), but will return an index to an element even if an exact match couldn't be found. The index is guaranteed to point at the element where the searched-for key would be inserted to preserve sorting order. [Richard Levitte] *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but takes an extra flags argument for optional functionality. Currently, the following flags are defined: OBJ_BSEARCH_VALUE_ON_NOMATCH This one gets OBJ_bsearch_ex() to return a pointer to the first element where the comparing function returns a negative or zero number. OBJ_BSEARCH_FIRST_VALUE_ON_MATCH This one gets OBJ_bsearch_ex() to return a pointer to the first element where the comparing function returns zero. This is useful if there are more than one element where the comparing function returns zero. [Richard Levitte] *) Make it possible to create self-signed certificates with 'openssl ca' in such a way that the self-signed certificate becomes part of the CA database and uses the same mechanisms for serial number generation as all other certificate signing. The new flag '-selfsign' enables this functionality. Adapt CA.sh and CA.pl.in. [Richard Levitte] *) Add functionality to check the public key of a certificate request against a given private. This is useful to check that a certificate request can be signed by that key (self-signing). [Richard Levitte] *) Make it possible to have multiple active certificates with the same subject in the CA index file. This is done only if the keyword 'unique_subject' is set to 'no' in the main CA section (default if 'CA_default') of the configuration file. The value is saved with the database itself in a separate index attribute file, named like the index file with '.attr' appended to the name. [Richard Levitte] *) Generate muti valued AVAs using '+' notation in config files for req and dirName. [Steve Henson] *) Support for nameConstraints certificate extension. [Steve Henson] *) Support for policyConstraints certificate extension. [Steve Henson] *) Support for policyMappings certificate extension. [Steve Henson] *) Make sure the default DSA_METHOD implementation only uses its dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL, and change its own handlers to be NULL so as to remove unnecessary indirection. This lets alternative implementations fallback to the default implementation more easily. [Geoff Thorpe] *) Support for directoryName in GeneralName related extensions in config files. [Steve Henson] *) Make it possible to link applications using Makefile.shared. Make that possible even when linking against static libraries! [Richard Levitte] *) Support for single pass processing for S/MIME signing. This now means that S/MIME signing can be done from a pipe, in addition cleartext signing (multipart/signed type) is effectively streaming and the signed data does not need to be all held in memory. This is done with a new flag PKCS7_STREAM. When this flag is set PKCS7_sign() only initializes the PKCS7 structure and the actual signing is done after the data is output (and digests calculated) in SMIME_write_PKCS7(). [Steve Henson] *) Add full support for -rpath/-R, both in shared libraries and applications, at least on the platforms where it's known how to do it. [Richard Levitte] *) In crypto/ec/ec_mult.c, implement fast point multiplication with precomputation, based on wNAF splitting: EC_GROUP_precompute_mult() will now compute a table of multiples of the generator that makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul() faster (notably in the case of a single point multiplication, scalar * generator). [Nils Larsch, Bodo Moeller] *) IPv6 support for certificate extensions. The various extensions which use the IP:a.b.c.d can now take IPv6 addresses using the formats of RFC1884 2.2 . IPv6 addresses are now also displayed correctly. [Steve Henson] *) Added an ENGINE that implements RSA by performing private key exponentiations with the GMP library. The conversions to and from GMP's mpz_t format aren't optimised nor are any montgomery forms cached, and on x86 it appears OpenSSL's own performance has caught up. However there are likely to be other architectures where GMP could provide a boost. This ENGINE is not built in by default, but it can be specified at Configure time and should be accompanied by the necessary linker additions, eg; ./config -DOPENSSL_USE_GMP -lgmp [Geoff Thorpe] *) "openssl engine" will not display ENGINE/DSO load failure errors when testing availability of engines with "-t" - the old behaviour is produced by increasing the feature's verbosity with "-tt". [Geoff Thorpe] *) ECDSA routines: under certain error conditions uninitialized BN objects could be freed. Solution: make sure initialization is performed early enough. (Reported and fix supplied by Nils Larsch via PR#459) [Lutz Jaenicke] *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD and DH_METHOD (eg. by ENGINE implementations) to override the normal software implementations. For DSA and DH, parameter generation can also be overriden by providing the appropriate method callbacks. [Geoff Thorpe] *) Change the "progress" mechanism used in key-generation and primality testing to functions that take a new BN_GENCB pointer in place of callback/argument pairs. The new API functions have "_ex" postfixes and the older functions are reimplemented as wrappers for the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide declarations of the old functions to help (graceful) attempts to migrate to the new functions. Also, the new key-generation API functions operate on a caller-supplied key-structure and return success/failure rather than returning a key or NULL - this is to help make "keygen" another member function of RSA_METHOD etc. Example for using the new callback interface: int (*my_callback)(int a, int b, BN_GENCB *cb) = ...; void *my_arg = ...; BN_GENCB my_cb; BN_GENCB_set(&my_cb, my_callback, my_arg); return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb); /* For the meaning of a, b in calls to my_callback(), see the * documentation of the function that calls the callback. * cb will point to my_cb; my_arg can be retrieved as cb->arg. * my_callback should return 1 if it wants BN_is_prime_ex() * to continue, or 0 to stop. */ [Geoff Thorpe] *) Change the ZLIB compression method to be stateful, and make it available to TLS with the number defined in draft-ietf-tls-compression-04.txt. [Richard Levitte] *) Add the ASN.1 structures and functions for CertificatePair, which is defined as follows (according to X.509_4thEditionDraftV6.pdf): CertificatePair ::= SEQUENCE { forward [0] Certificate OPTIONAL, reverse [1] Certificate OPTIONAL, -- at least one of the pair shall be present -- } Also implement the PEM functions to read and write certificate pairs, and defined the PEM tag as "CERTIFICATE PAIR". This needed to be defined, mostly for the sake of the LDAP attribute crossCertificatePair, but may prove useful elsewhere as well. [Richard Levitte] *) Make it possible to inhibit symlinking of shared libraries in Makefile.shared, for Cygwin's sake. [Richard Levitte] *) Extend the BIGNUM API by creating a function void BN_set_negative(BIGNUM *a, int neg); and a macro that behave like int BN_is_negative(const BIGNUM *a); to avoid the need to access 'a->neg' directly in applications. [Nils Larsch] *) Implement fast modular reduction for pseudo-Mersenne primes used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c). EC_GROUP_new_curve_GFp() will now automatically use this if applicable. [Nils Larsch ] *) Add new lock type (CRYPTO_LOCK_BN). [Bodo Moeller] *) Change the ENGINE framework to automatically load engines dynamically from specific directories unless they could be found to already be built in or loaded. Move all the current engines except for the cryptodev one to a new directory engines/. The engines in engines/ are built as shared libraries if the "shared" options was given to ./Configure or ./config. Otherwise, they are inserted in libcrypto.a. /usr/local/ssl/engines is the default directory for dynamic engines, but that can be overriden at configure time through the usual use of --prefix and/or --openssldir, and at run time with the environment variable OPENSSL_ENGINES. [Geoff Thorpe and Richard Levitte] *) Add Makefile.shared, a helper makefile to build shared libraries. Addapt Makefile.org. [Richard Levitte] *) Add version info to Win32 DLLs. [Peter 'Luna' Runestig" ] *) Add new 'medium level' PKCS#12 API. Certificates and keys can be added using this API to created arbitrary PKCS#12 files while avoiding the low level API. New options to PKCS12_create(), key or cert can be NULL and will then be omitted from the output file. The encryption algorithm NIDs can be set to -1 for no encryption, the mac iteration count can be set to 0 to omit the mac. Enhance pkcs12 utility by making the -nokeys and -nocerts options work when creating a PKCS#12 file. New option -nomac to omit the mac, NONE can be set for an encryption algorithm. New code is modified to use the enhanced PKCS12_create() instead of the low level API. [Steve Henson] *) Extend ASN1 encoder to support indefinite length constructed encoding. This can output sequences tags and octet strings in this form. Modify pk7_asn1.c to support indefinite length encoding. This is experimental and needs additional code to be useful, such as an ASN1 bio and some enhanced streaming PKCS#7 code. Extend template encode functionality so that tagging is passed down to the template encoder. [Steve Henson] *) Let 'openssl req' fail if an argument to '-newkey' is not recognized instead of using RSA as a default. [Bodo Moeller] *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt. As these are not official, they are not included in "ALL"; the "ECCdraft" ciphersuite group alias can be used to select them. [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)] *) Add ECDH engine support. [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)] *) Add ECDH in new directory crypto/ecdh/. [Douglas Stebila (Sun Microsystems Laboratories)] *) Let BN_rand_range() abort with an error after 100 iterations without success (which indicates a broken PRNG). [Bodo Moeller] *) Change BN_mod_sqrt() so that it verifies that the input value is really the square of the return value. (Previously, BN_mod_sqrt would show GIGO behaviour.) [Bodo Moeller] *) Add named elliptic curves over binary fields from X9.62, SECG, and WAP/WTLS; add OIDs that were still missing. [Sheueling Chang Shantz and Douglas Stebila (Sun Microsystems Laboratories)] *) Extend the EC library for elliptic curves over binary fields (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/). New EC_METHOD: EC_GF2m_simple_method New API functions: EC_GROUP_new_curve_GF2m EC_GROUP_set_curve_GF2m EC_GROUP_get_curve_GF2m EC_POINT_set_affine_coordinates_GF2m EC_POINT_get_affine_coordinates_GF2m EC_POINT_set_compressed_coordinates_GF2m Point compression for binary fields is disabled by default for patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to enable it). As binary polynomials are represented as BIGNUMs, various members of the EC_GROUP and EC_POINT data structures can be shared between the implementations for prime fields and binary fields; the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m) are essentially identical to their ..._GFp counterparts. (For simplicity, the '..._GFp' prefix has been dropped from various internal method names.) An internal 'field_div' method (similar to 'field_mul' and 'field_sqr') has been added; this is used only for binary fields. [Sheueling Chang Shantz and Douglas Stebila (Sun Microsystems Laboratories)] *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult() through methods ('mul', 'precompute_mult'). The generic implementations (now internally called 'ec_wNAF_mul' and 'ec_wNAF_precomputed_mult') remain the default if these methods are undefined. [Sheueling Chang Shantz and Douglas Stebila (Sun Microsystems Laboratories)] *) New function EC_GROUP_get_degree, which is defined through EC_METHOD. For curves over prime fields, this returns the bit length of the modulus. [Sheueling Chang Shantz and Douglas Stebila (Sun Microsystems Laboratories)] *) New functions EC_GROUP_dup, EC_POINT_dup. (These simply call ..._new and ..._copy). [Sheueling Chang Shantz and Douglas Stebila (Sun Microsystems Laboratories)] *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c. Polynomials are represented as BIGNUMs (where the sign bit is not used) in the following functions [macros]: BN_GF2m_add BN_GF2m_sub [= BN_GF2m_add] BN_GF2m_mod [wrapper for BN_GF2m_mod_arr] BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr] BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr] BN_GF2m_mod_inv BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr] BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr] BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr] BN_GF2m_cmp [= BN_ucmp] (Note that only the 'mod' functions are actually for fields GF(2^m). BN_GF2m_add() is misnomer, but this is for the sake of consistency.) For some functions, an the irreducible polynomial defining a field can be given as an 'unsigned int[]' with strictly decreasing elements giving the indices of those bits that are set; i.e., p[] represents the polynomial f(t) = t^p[0] + t^p[1] + ... + t^p[k] where p[0] > p[1] > ... > p[k] = 0. This applies to the following functions: BN_GF2m_mod_arr BN_GF2m_mod_mul_arr BN_GF2m_mod_sqr_arr BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv] BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div] BN_GF2m_mod_exp_arr BN_GF2m_mod_sqrt_arr BN_GF2m_mod_solve_quad_arr BN_GF2m_poly2arr BN_GF2m_arr2poly Conversion can be performed by the following functions: BN_GF2m_poly2arr BN_GF2m_arr2poly bntest.c has additional tests for binary polynomial arithmetic. Two implementations for BN_GF2m_mod_div() are available. The default algorithm simply uses BN_GF2m_mod_inv() and BN_GF2m_mod_mul(). The alternative algorithm is compiled in only if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the copyright notice in crypto/bn/bn_gf2m.c before enabling it). [Sheueling Chang Shantz and Douglas Stebila (Sun Microsystems Laboratories)] *) Add new error code 'ERR_R_DISABLED' that can be used when some functionality is disabled at compile-time. [Douglas Stebila ] *) Change default behaviour of 'openssl asn1parse' so that more information is visible when viewing, e.g., a certificate: Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump' mode the content of non-printable OCTET STRINGs is output in a style similar to INTEGERs, but with '[HEX DUMP]' prepended to avoid the appearance of a printable string. [Nils Larsch ] *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access functions EC_GROUP_set_asn1_flag() EC_GROUP_get_asn1_flag() EC_GROUP_set_point_conversion_form() EC_GROUP_get_point_conversion_form() These control ASN1 encoding details: - Curves (i.e., groups) are encoded explicitly unless asn1_flag has been set to OPENSSL_EC_NAMED_CURVE. - Points are encoded in uncompressed form by default; options for asn1_for are as for point2oct, namely POINT_CONVERSION_COMPRESSED POINT_CONVERSION_UNCOMPRESSED POINT_CONVERSION_HYBRID Also add 'seed' and 'seed_len' members to EC_GROUP with access functions EC_GROUP_set_seed() EC_GROUP_get0_seed() EC_GROUP_get_seed_len() This is used only for ASN1 purposes (so far). [Nils Larsch ] *) Add 'field_type' member to EC_METHOD, which holds the NID of the appropriate field type OID. The new function EC_METHOD_get_field_type() returns this value. [Nils Larsch ] *) Add functions EC_POINT_point2bn() EC_POINT_bn2point() EC_POINT_point2hex() EC_POINT_hex2point() providing useful interfaces to EC_POINT_point2oct() and EC_POINT_oct2point(). [Nils Larsch ] *) Change internals of the EC library so that the functions EC_GROUP_set_generator() EC_GROUP_get_generator() EC_GROUP_get_order() EC_GROUP_get_cofactor() are implemented directly in crypto/ec/ec_lib.c and not dispatched to methods, which would lead to unnecessary code duplication when adding different types of curves. [Nils Larsch with input by Bodo Moeller] *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM arithmetic, and such that modified wNAFs are generated (which avoid length expansion in many cases). [Bodo Moeller] *) Add a function EC_GROUP_check_discriminant() (defined via EC_METHOD) that verifies that the curve discriminant is non-zero. Add a function EC_GROUP_check() that makes some sanity tests on a EC_GROUP, its generator and order. This includes EC_GROUP_check_discriminant(). [Nils Larsch ] *) Add ECDSA in new directory crypto/ecdsa/. Add applications 'openssl ecparam' and 'openssl ecdsa' (these are based on 'openssl dsaparam' and 'openssl dsa'). ECDSA support is also included in various other files across the library. Most notably, - 'openssl req' now has a '-newkey ecdsa:file' option; - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA; - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make them suitable for ECDSA where domain parameters must be extracted before the specific public key; - ECDSA engine support has been added. [Nils Larsch ] *) Include some named elliptic curves, and add OIDs from X9.62, SECG, and WAP/WTLS. Each curve can be obtained from the new function EC_GROUP_new_by_curve_name(), and the list of available named curves can be obtained with EC_get_builtin_curves(). Also add a 'curve_name' member to EC_GROUP objects, which can be accessed via EC_GROUP_set_curve_name() EC_GROUP_get_curve_name() [Nils Larsch ] *) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that a ciphersuite string such as "DEFAULT:RSA" cannot enable authentication-only ciphersuites. [Bodo Moeller] *) Since AES128 and AES256 share a single mask bit in the logic of ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a kludge to work properly if AES128 is available and AES256 isn't. [Victor Duchovni] *) Expand security boundary to match 1.1.1 module. [Steve Henson] *) Remove redundant features: hash file source, editing of test vectors modify fipsld to use external fips_premain.c signature. [Steve Henson] *) New perl script mkfipsscr.pl to create shell scripts or batch files to run algorithm test programs. [Steve Henson] *) Make algorithm test programs more tolerant of whitespace. [Steve Henson] *) Have SSL/TLS server implementation tolerate "mismatched" record protocol version while receiving ClientHello even if the ClientHello is fragmented. (The server can't insist on the particular protocol version it has chosen before the ServerHello message has informed the client about his choice.) [Bodo Moeller] *) Load error codes if they are not already present instead of using a static variable. This allows them to be cleanly unloaded and reloaded. [Steve Henson] Changes between 0.9.7k and 0.9.7l [28 Sep 2006] *) Introduce limits to prevent malicious keys being able to cause a denial of service. (CVE-2006-2940) [Steve Henson, Bodo Moeller] *) Fix ASN.1 parsing of certain invalid structures that can result in a denial of service. (CVE-2006-2937) [Steve Henson] *) Fix buffer overflow in SSL_get_shared_ciphers() function. (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team] *) Fix SSL client code which could crash if connecting to a malicious SSLv2 server. (CVE-2006-4343) [Tavis Ormandy and Will Drewry, Google Security Team] *) Change ciphersuite string processing so that an explicit ciphersuite selects this one ciphersuite (so that "AES256-SHA" will no longer include "AES128-SHA"), and any other similar ciphersuite (same bitmap) from *other* protocol versions (so that "RC4-MD5" will still include both the SSL 2.0 ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite). This is a backport combining changes from 0.9.8b and 0.9.8d. [Bodo Moeller] Changes between 0.9.7j and 0.9.7k [05 Sep 2006] *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher (CVE-2006-4339) [Ben Laurie and Google Security Team] *) Change the Unix randomness entropy gathering to use poll() when possible instead of select(), since the latter has some undesirable limitations. [Darryl Miles via Richard Levitte and Bodo Moeller] *) Disable rogue ciphersuites: - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5") - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5") - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5") The latter two were purportedly from draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really appear there. Also deactive the remaining ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as unofficial, and the ID has long expired. [Bodo Moeller] *) Fix RSA blinding Heisenbug (problems sometimes occured on dual-core machines) and other potential thread-safety issues. [Bodo Moeller] Changes between 0.9.7i and 0.9.7j [04 May 2006] *) Adapt fipsld and the build system to link against the validated FIPS module in FIPS mode. [Steve Henson] *) Fixes for VC++ 2005 build under Windows. [Steve Henson] *) Add new Windows build target VC-32-GMAKE for VC++. This uses GNU make from a Windows bash shell such as MSYS. It is autodetected from the "config" script when run from a VC++ environment. Modify standard VC++ build to use fipscanister.o from the GNU make build. [Steve Henson] Changes between 0.9.7h and 0.9.7i [14 Oct 2005] *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS. The value now differs depending on if you build for FIPS or not. BEWARE! A program linked with a shared FIPSed libcrypto can't be safely run with a non-FIPSed libcrypto, as it may crash because of the difference induced by this change. [Andy Polyakov] Changes between 0.9.7g and 0.9.7h [11 Oct 2005] *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING (part of SSL_OP_ALL). This option used to disable the countermeasure against man-in-the-middle protocol-version rollback in the SSL 2.0 server implementation, which is a bad idea. (CVE-2005-2969) [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center for Information Security, National Institute of Advanced Industrial Science and Technology [AIST], Japan)] *) Minimal support for X9.31 signatures and PSS padding modes. This is mainly for FIPS compliance and not fully integrated at this stage. [Steve Henson] *) For DSA signing, unless DSA_FLAG_NO_EXP_CONSTTIME is set, perform the exponentiation using a fixed-length exponent. (Otherwise, the information leaked through timing could expose the secret key after many signatures; cf. Bleichenbacher's attack on DSA with biased k.) [Bodo Moeller] *) Make a new fixed-window mod_exp implementation the default for RSA, DSA, and DH private-key operations so that the sequence of squares and multiplies and the memory access pattern are independent of the particular secret key. This will mitigate cache-timing and potential related attacks. BN_mod_exp_mont_consttime() is the new exponentiation implementation, and this is automatically used by BN_mod_exp_mont() if the new flag BN_FLG_EXP_CONSTTIME is set for the exponent. RSA, DSA, and DH will use this BN flag for private exponents unless the flag RSA_FLAG_NO_EXP_CONSTTIME, DSA_FLAG_NO_EXP_CONSTTIME, or DH_FLAG_NO_EXP_CONSTTIME, respectively, is set. [Matthew D Wood (Intel Corp), with some changes by Bodo Moeller] *) Change the client implementation for SSLv23_method() and SSLv23_client_method() so that is uses the SSL 3.0/TLS 1.0 Client Hello message format if the SSL_OP_NO_SSLv2 option is set. (Previously, the SSL 2.0 backwards compatible Client Hello message format would be used even with SSL_OP_NO_SSLv2.) [Bodo Moeller] *) Add support for smime-type MIME parameter in S/MIME messages which some clients need. [Steve Henson] *) New function BN_MONT_CTX_set_locked() to set montgomery parameters in a threadsafe manner. Modify rsa code to use new function and add calls to dsa and dh code (which had race conditions before). [Steve Henson] *) Include the fixed error library code in the C error file definitions instead of fixing them up at runtime. This keeps the error code structures constant. [Steve Henson] Changes between 0.9.7f and 0.9.7g [11 Apr 2005] [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after OpenSSL 0.9.8.] *) Fixes for newer kerberos headers. NB: the casts are needed because the 'length' field is signed on one version and unsigned on another with no (?) obvious way to tell the difference, without these VC++ complains. Also the "definition" of FAR (blank) is no longer included nor is the error ENOMEM. KRB5_PRIVATE has to be set to 1 to pick up some needed definitions. [Steve Henson] *) Undo Cygwin change. [Ulf Möller] *) Added support for proxy certificates according to RFC 3820. Because they may be a security thread to unaware applications, they must be explicitely allowed in run-time. See docs/HOWTO/proxy_certificates.txt for further information. [Richard Levitte] Changes between 0.9.7e and 0.9.7f [22 Mar 2005] *) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating server and client random values. Previously (SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in less random data when sizeof(time_t) > 4 (some 64 bit platforms). This change has negligible security impact because: 1. Server and client random values still have 24 bytes of pseudo random data. 2. Server and client random values are sent in the clear in the initial handshake. 3. The master secret is derived using the premaster secret (48 bytes in size for static RSA ciphersuites) as well as client server and random values. The OpenSSL team would like to thank the UK NISCC for bringing this issue to our attention. [Stephen Henson, reported by UK NISCC] *) Use Windows randomness collection on Cygwin. [Ulf Möller] *) Fix hang in EGD/PRNGD query when communication socket is closed prematurely by EGD/PRNGD. [Darren Tucker via Lutz Jänicke, resolves #1014] *) Prompt for pass phrases when appropriate for PKCS12 input format. [Steve Henson] *) Back-port of selected performance improvements from development branch, as well as improved support for PowerPC platforms. [Andy Polyakov] *) Add lots of checks for memory allocation failure, error codes to indicate failure and freeing up memory if a failure occurs. [Nauticus Networks SSL Team , Steve Henson] *) Add new -passin argument to dgst. [Steve Henson] *) Perform some character comparisons of different types in X509_NAME_cmp: this is needed for some certificates that reencode DNs into UTF8Strings (in violation of RFC3280) and can't or wont issue name rollover certificates. [Steve Henson] *) Make an explicit check during certificate validation to see that the CA setting in each certificate on the chain is correct. As a side effect always do the following basic checks on extensions, not just when there's an associated purpose to the check: - if there is an unhandled critical extension (unless the user has chosen to ignore this fault) - if the path length has been exceeded (if one is set at all) - that certain extensions fit the associated purpose (if one has been given) [Richard Levitte] Changes between 0.9.7d and 0.9.7e [25 Oct 2004] *) Avoid a race condition when CRLs are checked in a multi threaded environment. This would happen due to the reordering of the revoked entries during signature checking and serial number lookup. Now the encoding is cached and the serial number sort performed under a lock. Add new STACK function sk_is_sorted(). [Steve Henson] *) Add Delta CRL to the extension code. [Steve Henson] *) Various fixes to s3_pkt.c so alerts are sent properly. [David Holmes ] *) Reduce the chances of duplicate issuer name and serial numbers (in violation of RFC3280) using the OpenSSL certificate creation utilities. This is done by creating a random 64 bit value for the initial serial number when a serial number file is created or when a self signed certificate is created using 'openssl req -x509'. The initial serial number file is created using 'openssl x509 -next_serial' in CA.pl rather than being initialized to 1. [Steve Henson] Changes between 0.9.7c and 0.9.7d [17 Mar 2004] *) Fix null-pointer assignment in do_change_cipher_spec() revealed by using the Codenomicon TLS Test Tool (CVE-2004-0079) [Joe Orton, Steve Henson] *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites (CVE-2004-0112) [Joe Orton, Steve Henson] *) Make it possible to have multiple active certificates with the same subject in the CA index file. This is done only if the keyword 'unique_subject' is set to 'no' in the main CA section (default if 'CA_default') of the configuration file. The value is saved with the database itself in a separate index attribute file, named like the index file with '.attr' appended to the name. [Richard Levitte] *) X509 verify fixes. Disable broken certificate workarounds when X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if keyUsage extension present. Don't accept CRLs with unhandled critical extensions: since verify currently doesn't process CRL extensions this rejects a CRL with *any* critical extensions. Add new verify error codes for these cases. [Steve Henson] *) When creating an OCSP nonce use an OCTET STRING inside the extnValue. A clarification of RFC2560 will require the use of OCTET STRINGs and some implementations cannot handle the current raw format. Since OpenSSL copies and compares OCSP nonces as opaque blobs without any attempt at parsing them this should not create any compatibility issues. [Steve Henson] *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without this HMAC (and other) operations are several times slower than OpenSSL < 0.9.7. [Steve Henson] *) Print out GeneralizedTime and UTCTime in ASN1_STRING_print_ex(). [Peter Sylvester ] *) Use the correct content when signing type "other". [Steve Henson] Changes between 0.9.7b and 0.9.7c [30 Sep 2003] *) Fix various bugs revealed by running the NISCC test suite: Stop out of bounds reads in the ASN1 code when presented with invalid tags (CVE-2003-0543 and CVE-2003-0544). Free up ASN1_TYPE correctly if ANY type is invalid (CVE-2003-0545). If verify callback ignores invalid public key errors don't try to check certificate signature with the NULL public key. [Steve Henson] *) New -ignore_err option in ocsp application to stop the server exiting on the first error in a request. [Steve Henson] *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate if the server requested one: as stated in TLS 1.0 and SSL 3.0 specifications. [Steve Henson] *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional extra data after the compression methods not only for TLS 1.0 but also for SSL 3.0 (as required by the specification). [Bodo Moeller; problem pointed out by Matthias Loepfe] *) Change X509_certificate_type() to mark the key as exported/exportable when it's 512 *bits* long, not 512 bytes. [Richard Levitte] *) Change AES_cbc_encrypt() so it outputs exact multiple of blocks during encryption. [Richard Levitte] *) Various fixes to base64 BIO and non blocking I/O. On write flushes were not handled properly if the BIO retried. On read data was not being buffered properly and had various logic bugs. This also affects blocking I/O when the data being decoded is a certain size. [Steve Henson] *) Various S/MIME bugfixes and compatibility changes: output correct application/pkcs7 MIME type if PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures. Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening of files as .eml work). Correctly handle very long lines in MIME parser. [Steve Henson] Changes between 0.9.7a and 0.9.7b [10 Apr 2003] *) Countermeasure against the Klima-Pokorny-Rosa extension of Bleichbacher's attack on PKCS #1 v1.5 padding: treat a protocol version number mismatch like a decryption error in ssl3_get_client_key_exchange (ssl/s3_srvr.c). [Bodo Moeller] *) Turn on RSA blinding by default in the default implementation to avoid a timing attack. Applications that don't want it can call RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING. They would be ill-advised to do so in most cases. [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller] *) Change RSA blinding code so that it works when the PRNG is not seeded (in this case, the secret RSA exponent is abused as an unpredictable seed -- if it is not unpredictable, there is no point in blinding anyway). Make RSA blinding thread-safe by remembering the creator's thread ID in rsa->blinding and having all other threads use local one-time blinding factors (this requires more computation than sharing rsa->blinding, but avoids excessive locking; and if an RSA object is not shared between threads, blinding will still be very fast). [Bodo Moeller] *) Fixed a typo bug that would cause ENGINE_set_default() to set an ENGINE as defaults for all supported algorithms irrespective of the 'flags' parameter. 'flags' is now honoured, so applications should make sure they are passing it correctly. [Geoff Thorpe] *) Target "mingw" now allows native Windows code to be generated in the Cygwin environment as well as with the MinGW compiler. [Ulf Moeller] Changes between 0.9.7 and 0.9.7a [19 Feb 2003] *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked via timing by performing a MAC computation even if incorrrect block cipher padding has been found. This is a countermeasure against active attacks where the attacker has to distinguish between bad padding and a MAC verification error. (CVE-2003-0078) [Bodo Moeller; problem pointed out by Brice Canvel (EPFL), Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and Martin Vuagnoux (EPFL, Ilion)] *) Make the no-err option work as intended. The intention with no-err is not to have the whole error stack handling routines removed from libcrypto, it's only intended to remove all the function name and reason texts, thereby removing some of the footprint that may not be interesting if those errors aren't displayed anyway. NOTE: it's still possible for any application or module to have it's own set of error texts inserted. The routines are there, just not used by default when no-err is given. [Richard Levitte] *) Add support for FreeBSD on IA64. [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454] *) Adjust DES_cbc_cksum() so it returns the same value as the MIT Kerberos function mit_des_cbc_cksum(). Before this change, the value returned by DES_cbc_cksum() was like the one from mit_des_cbc_cksum(), except the bytes were swapped. [Kevin Greaney and Richard Levitte] *) Allow an application to disable the automatic SSL chain building. Before this a rather primitive chain build was always performed in ssl3_output_cert_chain(): an application had no way to send the correct chain if the automatic operation produced an incorrect result. Now the chain builder is disabled if either: 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert(). 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set. The reasoning behind this is that an application would not want the auto chain building to take place if extra chain certificates are present and it might also want a means of sending no additional certificates (for example the chain has two certificates and the root is omitted). [Steve Henson] *) Add the possibility to build without the ENGINE framework. [Steven Reddie via Richard Levitte] *) Under Win32 gmtime() can return NULL: check return value in OPENSSL_gmtime(). Add error code for case where gmtime() fails. [Steve Henson] *) DSA routines: under certain error conditions uninitialized BN objects could be freed. Solution: make sure initialization is performed early enough. (Reported and fix supplied by Ivan D Nestlerode , Nils Larsch via PR#459) [Lutz Jaenicke] *) Another fix for SSLv2 session ID handling: the session ID was incorrectly checked on reconnect on the client side, therefore session resumption could still fail with a "ssl session id is different" error. This behaviour is masked when SSL_OP_ALL is used due to SSL_OP_MICROSOFT_SESS_ID_BUG being set. Behaviour observed by Crispin Flowerday as followup to PR #377. [Lutz Jaenicke] *) IA-32 assembler support enhancements: unified ELF targets, support for SCO/Caldera platforms, fix for Cygwin shared build. [Andy Polyakov] *) Add support for FreeBSD on sparc64. As a consequence, support for FreeBSD on non-x86 processors is separate from x86 processors on the config script, much like the NetBSD support. [Richard Levitte & Kris Kennaway ] Changes between 0.9.6h and 0.9.7 [31 Dec 2002] [NB: OpenSSL 0.9.6i and later 0.9.6 patch levels were released after OpenSSL 0.9.7.] *) Fix session ID handling in SSLv2 client code: the SERVER FINISHED code (06) was taken as the first octet of the session ID and the last octet was ignored consequently. As a result SSLv2 client side session caching could not have worked due to the session ID mismatch between client and server. Behaviour observed by Crispin Flowerday as PR #377. [Lutz Jaenicke] *) Change the declaration of needed Kerberos libraries to use EX_LIBS instead of the special (and badly supported) LIBKRB5. LIBKRB5 is removed entirely. [Richard Levitte] *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it seems that in spite of existing for more than a year, many application author have done nothing to provide the necessary callbacks, which means that this particular engine will not work properly anywhere. This is a very unfortunate situation which forces us, in the name of usability, to give the hw_ncipher.c a static lock, which is part of libcrypto. NOTE: This is for the 0.9.7 series ONLY. This hack will never appear in 0.9.8 or later. We EXPECT application authors to have dealt properly with this when 0.9.8 is released (unless we actually make such changes in the libcrypto locking code that changes will have to be made anyway). [Richard Levitte] *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content octets have been read, EOF or an error occurs. Without this change some truncated ASN1 structures will not produce an error. [Steve Henson] *) Disable Heimdal support, since it hasn't been fully implemented. Still give the possibility to force the use of Heimdal, but with warnings and a request that patches get sent to openssl-dev. [Richard Levitte] *) Add the VC-CE target, introduce the WINCE sysname, and add INSTALL.WCE and appropriate conditionals to make it build. [Steven Reddie via Richard Levitte] *) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and cygssl-x.y.z.dll, where x, y and z are the major, minor and edit numbers of the version. [Corinna Vinschen and Richard Levitte] *) Introduce safe string copy and catenation functions (BUF_strlcpy() and BUF_strlcat()). [Ben Laurie (CHATS) and Richard Levitte] *) Avoid using fixed-size buffers for one-line DNs. [Ben Laurie (CHATS)] *) Add BUF_MEM_grow_clean() to avoid information leakage when resizing buffers containing secrets, and use where appropriate. [Ben Laurie (CHATS)] *) Avoid using fixed size buffers for configuration file location. [Ben Laurie (CHATS)] *) Avoid filename truncation for various CA files. [Ben Laurie (CHATS)] *) Use sizeof in preference to magic numbers. [Ben Laurie (CHATS)] *) Avoid filename truncation in cert requests. [Ben Laurie (CHATS)] *) Add assertions to check for (supposedly impossible) buffer overflows. [Ben Laurie (CHATS)] *) Don't cache truncated DNS entries in the local cache (this could potentially lead to a spoofing attack). [Ben Laurie (CHATS)] *) Fix various buffers to be large enough for hex/decimal representations in a platform independent manner. [Ben Laurie (CHATS)] *) Add CRYPTO_realloc_clean() to avoid information leakage when resizing buffers containing secrets, and use where appropriate. [Ben Laurie (CHATS)] *) Add BIO_indent() to avoid much slightly worrying code to do indents. [Ben Laurie (CHATS)] *) Convert sprintf()/BIO_puts() to BIO_printf(). [Ben Laurie (CHATS)] *) buffer_gets() could terminate with the buffer only half full. Fixed. [Ben Laurie (CHATS)] *) Add assertions to prevent user-supplied crypto functions from overflowing internal buffers by having large block sizes, etc. [Ben Laurie (CHATS)] *) New OPENSSL_assert() macro (similar to assert(), but enabled unconditionally). [Ben Laurie (CHATS)] *) Eliminate unused copy of key in RC4. [Ben Laurie (CHATS)] *) Eliminate unused and incorrectly sized buffers for IV in pem.h. [Ben Laurie (CHATS)] *) Fix off-by-one error in EGD path. [Ben Laurie (CHATS)] *) If RANDFILE path is too long, ignore instead of truncating. [Ben Laurie (CHATS)] *) Eliminate unused and incorrectly sized X.509 structure CBCParameter. [Ben Laurie (CHATS)] *) Eliminate unused and dangerous function knumber(). [Ben Laurie (CHATS)] *) Eliminate unused and dangerous structure, KSSL_ERR. [Ben Laurie (CHATS)] *) Protect against overlong session ID context length in an encoded session object. Since these are local, this does not appear to be exploitable. [Ben Laurie (CHATS)] *) Change from security patch (see 0.9.6e below) that did not affect the 0.9.6 release series: Remote buffer overflow in SSL3 protocol - an attacker could supply an oversized master key in Kerberos-enabled versions. (CVE-2002-0657) [Ben Laurie (CHATS)] *) Change the SSL kerb5 codes to match RFC 2712. [Richard Levitte] *) Make -nameopt work fully for req and add -reqopt switch. [Michael Bell , Steve Henson] *) The "block size" for block ciphers in CFB and OFB mode should be 1. [Steve Henson, reported by Yngve Nysaeter Pettersen ] *) Make sure tests can be performed even if the corresponding algorithms have been removed entirely. This was also the last step to make OpenSSL compilable with DJGPP under all reasonable conditions. [Richard Levitte, Doug Kaufman ] *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT to allow version independent disabling of normally unselected ciphers, which may be activated as a side-effect of selecting a single cipher. (E.g., cipher list string "RSA" enables ciphersuites that are left out of "ALL" because they do not provide symmetric encryption. "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.) [Lutz Jaenicke, Bodo Moeller] *) Add appropriate support for separate platform-dependent build directories. The recommended way to make a platform-dependent build directory is the following (tested on Linux), maybe with some local tweaks: # Place yourself outside of the OpenSSL source tree. In # this example, the environment variable OPENSSL_SOURCE # is assumed to contain the absolute OpenSSL source directory. mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`" cd objtree/"`uname -s`-`uname -r`-`uname -m`" (cd $OPENSSL_SOURCE; find . -type f) | while read F; do mkdir -p `dirname $F` ln -s $OPENSSL_SOURCE/$F $F done To be absolutely sure not to disturb the source tree, a "make clean" is a good thing. If it isn't successfull, don't worry about it, it probably means the source directory is very clean. [Richard Levitte] *) Make sure any ENGINE control commands make local copies of string pointers passed to them whenever necessary. Otherwise it is possible the caller may have overwritten (or deallocated) the original string data when a later ENGINE operation tries to use the stored values. [Götz Babin-Ebell ] *) Improve diagnostics in file reading and command-line digests. [Ben Laurie aided and abetted by Solar Designer ] *) Add AES modes CFB and OFB to the object database. Correct an error in AES-CFB decryption. [Richard Levitte] *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this allows existing EVP_CIPHER_CTX structures to be reused after calling EVP_*Final(). This behaviour is used by encryption BIOs and some applications. This has the side effect that applications must explicitly clean up cipher contexts with EVP_CIPHER_CTX_cleanup() or they will leak memory. [Steve Henson] *) Check the values of dna and dnb in bn_mul_recursive before calling bn_mul_comba (a non zero value means the a or b arrays do not contain n2 elements) and fallback to bn_mul_normal if either is not zero. [Steve Henson] *) Fix escaping of non-ASCII characters when using the -subj option of the "openssl req" command line tool. (Robert Joop ) [Lutz Jaenicke] *) Make object definitions compliant to LDAP (RFC2256): SN is the short form for "surname", serialNumber has no short form. Use "mail" as the short name for "rfc822Mailbox" according to RFC2798; therefore remove "mail" short name for "internet 7". The OID for unique identifiers in X509 certificates is x500UniqueIdentifier, not uniqueIdentifier. Some more OID additions. (Michael Bell ) [Lutz Jaenicke] *) Add an "init" command to the ENGINE config module and auto initialize ENGINEs. Without any "init" command the ENGINE will be initialized after all ctrl commands have been executed on it. If init=1 the ENGINE is initailized at that point (ctrls before that point are run on the uninitialized ENGINE and after on the initialized one). If init=0 then the ENGINE will not be iniatialized at all. [Steve Henson] *) Fix the 'app_verify_callback' interface so that the user-defined argument is actually passed to the callback: In the SSL_CTX_set_cert_verify_callback() prototype, the callback declaration has been changed from int (*cb)() into int (*cb)(X509_STORE_CTX *,void *); in ssl_verify_cert_chain (ssl/ssl_cert.c), the call i=s->ctx->app_verify_callback(&ctx) has been changed into i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg). To update applications using SSL_CTX_set_cert_verify_callback(), a dummy argument can be added to their callback functions. [D. K. Smetters ] *) Added the '4758cca' ENGINE to support IBM 4758 cards. [Maurice Gittens , touchups by Geoff Thorpe] *) Add and OPENSSL_LOAD_CONF define which will cause OpenSSL_add_all_algorithms() to load the openssl.cnf config file. This allows older applications to transparently support certain OpenSSL features: such as crypto acceleration and dynamic ENGINE loading. Two new functions OPENSSL_add_all_algorithms_noconf() which will never load the config file and OPENSSL_add_all_algorithms_conf() which will always load it have also been added. [Steve Henson] *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES. Adjust NIDs and EVP layer. [Stephen Sprunk and Richard Levitte] *) Config modules support in openssl utility. Most commands now load modules from the config file, though in a few (such as version) this isn't done because it couldn't be used for anything. In the case of ca and req the config file used is the same as the utility itself: that is the -config command line option can be used to specify an alternative file. [Steve Henson] *) Move default behaviour from OPENSSL_config(). If appname is NULL use "openssl_conf" if filename is NULL use default openssl config file. [Steve Henson] *) Add an argument to OPENSSL_config() to allow the use of an alternative config section name. Add a new flag to tolerate a missing config file and move code to CONF_modules_load_file(). [Steve Henson] *) Support for crypto accelerator cards from Accelerated Encryption Processing, www.aep.ie. (Use engine 'aep') The support was copied from 0.9.6c [engine] and adapted/corrected to work with the new engine framework. [AEP Inc. and Richard Levitte] *) Support for SureWare crypto accelerator cards from Baltimore Technologies. (Use engine 'sureware') The support was copied from 0.9.6c [engine] and adapted to work with the new engine framework. [Richard Levitte] *) Have the CHIL engine fork-safe (as defined by nCipher) and actually make the newer ENGINE framework commands for the CHIL engine work. [Toomas Kiisk and Richard Levitte] *) Make it possible to produce shared libraries on ReliantUNIX. [Robert Dahlem via Richard Levitte] *) Add the configuration target debug-linux-ppro. Make 'openssl rsa' use the general key loading routines implemented in apps.c, and make those routines able to handle the key format FORMAT_NETSCAPE and the variant FORMAT_IISSGC. [Toomas Kiisk via Richard Levitte] *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey(). [Toomas Kiisk via Richard Levitte] *) Add -keyform to rsautl, and document -engine. [Richard Levitte, inspired by Toomas Kiisk ] *) Change BIO_new_file (crypto/bio/bss_file.c) to use new BIO_R_NO_SUCH_FILE error code rather than the generic ERR_R_SYS_LIB error code if fopen() fails with ENOENT. [Ben Laurie] *) Add new functions ERR_peek_last_error ERR_peek_last_error_line ERR_peek_last_error_line_data. These are similar to ERR_peek_error ERR_peek_error_line ERR_peek_error_line_data, but report on the latest error recorded rather than the first one still in the error queue. [Ben Laurie, Bodo Moeller] *) default_algorithms option in ENGINE config module. This allows things like: default_algorithms = ALL default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS [Steve Henson] *) Prelminary ENGINE config module. [Steve Henson] *) New experimental application configuration code. [Steve Henson] *) Change the AES code to follow the same name structure as all other symmetric ciphers, and behave the same way. Move everything to the directory crypto/aes, thereby obsoleting crypto/rijndael. [Stephen Sprunk and Richard Levitte] *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c. [Ben Laurie and Theo de Raadt] *) Add option to output public keys in req command. [Massimiliano Pala madwolf@openca.org] *) Use wNAFs in EC_POINTs_mul() for improved efficiency (up to about 10% better than before for P-192 and P-224). [Bodo Moeller] *) New functions/macros SSL_CTX_set_msg_callback(ctx, cb) SSL_CTX_set_msg_callback_arg(ctx, arg) SSL_set_msg_callback(ssl, cb) SSL_set_msg_callback_arg(ssl, arg) to request calling a callback function void cb(int write_p, int version, int content_type, const void *buf, size_t len, SSL *ssl, void *arg) whenever a protocol message has been completely received (write_p == 0) or sent (write_p == 1). Here 'version' is the protocol version according to which the SSL library interprets the current protocol message (SSL2_VERSION, SSL3_VERSION, or TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or the content type as defined in the SSL 3.0/TLS 1.0 protocol specification (change_cipher_spec(20), alert(21), handshake(22)). 'buf' and 'len' point to the actual message, 'ssl' to the SSL object, and 'arg' is the application-defined value set by SSL[_CTX]_set_msg_callback_arg(). 'openssl s_client' and 'openssl s_server' have new '-msg' options to enable a callback that displays all protocol messages. [Bodo Moeller] *) Change the shared library support so shared libraries are built as soon as the corresponding static library is finished, and thereby get openssl and the test programs linked against the shared library. This still only happens when the keyword "shard" has been given to the configuration scripts. NOTE: shared library support is still an experimental thing, and backward binary compatibility is still not guaranteed. ["Maciej W. Rozycki" and Richard Levitte] *) Add support for Subject Information Access extension. [Peter Sylvester ] *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero additional bytes when new memory had to be allocated, not just when reusing an existing buffer. [Bodo Moeller] *) New command line and configuration option 'utf8' for the req command. This allows field values to be specified as UTF8 strings. [Steve Henson] *) Add -multi and -mr options to "openssl speed" - giving multiple parallel runs for the former and machine-readable output for the latter. [Ben Laurie] *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion of the e-mail address in the DN (i.e., it will go into a certificate extension only). The new configuration file option 'email_in_dn = no' has the same effect. [Massimiliano Pala madwolf@openca.org] *) Change all functions with names starting with des_ to be starting with DES_ instead. Add wrappers that are compatible with libdes, but are named _ossl_old_des_*. Finally, add macros that map the des_* symbols to the corresponding _ossl_old_des_* if libdes compatibility is desired. If OpenSSL 0.9.6c compatibility is desired, the des_* symbols will be mapped to DES_*, with one exception. Since we provide two compatibility mappings, the user needs to define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes compatibility is desired. The default (i.e., when that macro isn't defined) is OpenSSL 0.9.6c compatibility. There are also macros that enable and disable the support of old des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those are defined, the default will apply: to support the old des routines. In either case, one must include openssl/des.h to get the correct definitions. Do not try to just include openssl/des_old.h, that won't work. NOTE: This is a major break of an old API into a new one. Software authors are encouraged to switch to the DES_ style functions. Some time in the future, des_old.h and the libdes compatibility functions will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the default), and then completely removed. [Richard Levitte] *) Test for certificates which contain unsupported critical extensions. If such a certificate is found during a verify operation it is rejected by default: this behaviour can be overridden by either handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function X509_supported_extension() has also been added which returns 1 if a particular extension is supported. [Steve Henson] *) Modify the behaviour of EVP cipher functions in similar way to digests to retain compatibility with existing code. [Steve Henson] *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain compatibility with existing code. In particular the 'ctx' parameter does not have to be to be initialized before the call to EVP_DigestInit() and it is tidied up after a call to EVP_DigestFinal(). New function EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function EVP_MD_CTX_copy() changed to not require the destination to be initialized valid and new function EVP_MD_CTX_copy_ex() added which requires the destination to be valid. Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(), EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex(). [Steve Henson] *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it so that complete 'Handshake' protocol structures are kept in memory instead of overwriting 'msg_type' and 'length' with 'body' data. [Bodo Moeller] *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32. [Massimo Santin via Richard Levitte] *) Major restructuring to the underlying ENGINE code. This includes reduction of linker bloat, separation of pure "ENGINE" manipulation (initialisation, etc) from functionality dealing with implementations of specific crypto iterfaces. This change also introduces integrated support for symmetric ciphers and digest implementations - so ENGINEs can now accelerate these by providing EVP_CIPHER and EVP_MD implementations of their own. This is detailed in crypto/engine/README as it couldn't be adequately described here. However, there are a few API changes worth noting - some RSA, DSA, DH, and RAND functions that were changed in the original introduction of ENGINE code have now reverted back - the hooking from this code to ENGINE is now a good deal more passive and at run-time, operations deal directly with RSA_METHODs, DSA_METHODs (etc) as they did before, rather than dereferencing through an ENGINE pointer any more. Also, the ENGINE functions dealing with BN_MOD_EXP[_CRT] handlers have been removed - they were not being used by the framework as there is no concept of a BIGNUM_METHOD and they could not be generalised to the new 'ENGINE_TABLE' mechanism that underlies the new code. Similarly, ENGINE_cpy() has been removed as it cannot be consistently defined in the new code. [Geoff Thorpe] *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds. [Steve Henson] *) Change mkdef.pl to sort symbols that get the same entry number, and make sure the automatically generated functions ERR_load_* become part of libeay.num as well. [Richard Levitte] *) New function SSL_renegotiate_pending(). This returns true once renegotiation has been requested (either SSL_renegotiate() call or HelloRequest/ClientHello receveived from the peer) and becomes false once a handshake has been completed. (For servers, SSL_renegotiate() followed by SSL_do_handshake() sends a HelloRequest, but does not ensure that a handshake takes place. SSL_renegotiate_pending() is useful for checking if the client has followed the request.) [Bodo Moeller] *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION. By default, clients may request session resumption even during renegotiation (if session ID contexts permit); with this option, session resumption is possible only in the first handshake. SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes more bits available for options that should not be part of SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION). [Bodo Moeller] *) Add some demos for certificate and certificate request creation. [Steve Henson] *) Make maximum certificate chain size accepted from the peer application settable (SSL*_get/set_max_cert_list()), as proposed by "Douglas E. Engert" . [Lutz Jaenicke] *) Add support for shared libraries for Unixware-7 (Boyd Lynn Gerber ). [Lutz Jaenicke] *) Add a "destroy" handler to ENGINEs that allows structural cleanup to be done prior to destruction. Use this to unload error strings from ENGINEs that load their own error strings. NB: This adds two new API functions to "get" and "set" this destroy handler in an ENGINE. [Geoff Thorpe] *) Alter all existing ENGINE implementations (except "openssl" and "openbsd") to dynamically instantiate their own error strings. This makes them more flexible to be built both as statically-linked ENGINEs and self-contained shared-libraries loadable via the "dynamic" ENGINE. Also, add stub code to each that makes building them as self-contained shared-libraries easier (see README.ENGINE). [Geoff Thorpe] *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE implementations into applications that are completely implemented in self-contained shared-libraries. The "dynamic" ENGINE exposes control commands that can be used to configure what shared-library to load and to control aspects of the way it is handled. Also, made an update to the README.ENGINE file that brings its information up-to-date and provides some information and instructions on the "dynamic" ENGINE (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc). [Geoff Thorpe] *) Make it possible to unload ranges of ERR strings with a new "ERR_unload_strings" function. [Geoff Thorpe] *) Add a copy() function to EVP_MD. [Ben Laurie] *) Make EVP_MD routines take a context pointer instead of just the md_data void pointer. [Ben Laurie] *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates that the digest can only process a single chunk of data (typically because it is provided by a piece of hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application is only going to provide a single chunk of data, and hence the framework needn't accumulate the data for oneshot drivers. [Ben Laurie] *) As with "ERR", make it possible to replace the underlying "ex_data" functions. This change also alters the storage and management of global ex_data state - it's now all inside ex_data.c and all "class" code (eg. RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class index counters. The API functions that use this state have been changed to take a "class_index" rather than pointers to the class's local STACK and counter, and there is now an API function to dynamically create new classes. This centralisation allows us to (a) plug a lot of the thread-safety problems that existed, and (b) makes it possible to clean up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b) such data would previously have always leaked in application code and workarounds were in place to make the memory debugging turn a blind eye to it. Application code that doesn't use this new function will still leak as before, but their memory debugging output will announce it now rather than letting it slide. Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now has a return value to indicate success or failure. [Geoff Thorpe] *) Make it possible to replace the underlying "ERR" functions such that the global state (2 LHASH tables and 2 locks) is only used by the "default" implementation. This change also adds two functions to "get" and "set" the implementation prior to it being automatically set the first time any other ERR function takes place. Ie. an application can call "get", pass the return value to a module it has just loaded, and that module can call its own "set" function using that value. This means the module's "ERR" operations will use (and modify) the error state in the application and not in its own statically linked copy of OpenSSL code. [Geoff Thorpe] *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment reference counts. This performs normal REF_PRINT/REF_CHECK macros on the operation, and provides a more encapsulated way for external code (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code to use these functions rather than manually incrementing the counts. Also rename "DSO_up()" function to more descriptive "DSO_up_ref()". [Geoff Thorpe] *) Add EVP test program. [Ben Laurie] *) Add symmetric cipher support to ENGINE. Expect the API to change! [Ben Laurie] *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name() X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(), X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate(). These allow a CRL to be built without having to access X509_CRL fields directly. Modify 'ca' application to use new functions. [Steve Henson] *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended bug workarounds. Rollback attack detection is a security feature. The problem will only arise on OpenSSL servers when TLSv1 is not available (sslv3_server_method() or SSL_OP_NO_TLSv1). Software authors not wanting to support TLSv1 will have special reasons for their choice and can explicitly enable this option. [Bodo Moeller, Lutz Jaenicke] *) Rationalise EVP so it can be extended: don't include a union of cipher/digest structures, add init/cleanup functions for EVP_MD_CTX (similar to those existing for EVP_CIPHER_CTX). Usage example: EVP_MD_CTX md; EVP_MD_CTX_init(&md); /* new function call */ EVP_DigestInit(&md, EVP_sha1()); EVP_DigestUpdate(&md, in, len); EVP_DigestFinal(&md, out, NULL); EVP_MD_CTX_cleanup(&md); /* new function call */ [Ben Laurie] *) Make DES key schedule conform to the usual scheme, as well as correcting its structure. This means that calls to DES functions now have to pass a pointer to a des_key_schedule instead of a plain des_key_schedule (which was actually always a pointer anyway): E.g., des_key_schedule ks; des_set_key_checked(..., &ks); des_ncbc_encrypt(..., &ks, ...); (Note that a later change renames 'des_...' into 'DES_...'.) [Ben Laurie] *) Initial reduction of linker bloat: the use of some functions, such as PEM causes large amounts of unused functions to be linked in due to poor organisation. For example pem_all.c contains every PEM function which has a knock on effect of linking in large amounts of (unused) ASN1 code. Grouping together similar functions and splitting unrelated functions prevents this. [Steve Henson] *) Cleanup of EVP macros. [Ben Laurie] *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the correct _ecb suffix. [Ben Laurie] *) Add initial OCSP responder support to ocsp application. The revocation information is handled using the text based index use by the ca application. The responder can either handle requests generated internally, supplied in files (for example via a CGI script) or using an internal minimal server. [Steve Henson] *) Add configuration choices to get zlib compression for TLS. [Richard Levitte] *) Changes to Kerberos SSL for RFC 2712 compliance: 1. Implemented real KerberosWrapper, instead of just using KRB5 AP_REQ message. [Thanks to Simon Wilkinson ] 2. Implemented optional authenticator field of KerberosWrapper. Added openssl-style ASN.1 macros for Kerberos ticket, ap_req, and authenticator structs; see crypto/krb5/. Generalized Kerberos calls to support multiple Kerberos libraries. [Vern Staats , Jeffrey Altman via Richard Levitte] *) Cause 'openssl speed' to use fully hard-coded DSA keys as it already does with RSA. testdsa.h now has 'priv_key/pub_key' values for each of the key sizes rather than having just parameters (and 'speed' generating keys each time). [Geoff Thorpe] *) Speed up EVP routines. Before: encrypt type 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes des-cbc 4408.85k 5560.51k 5778.46k 5862.20k 5825.16k des-cbc 4389.55k 5571.17k 5792.23k 5846.91k 5832.11k des-cbc 4394.32k 5575.92k 5807.44k 5848.37k 5841.30k decrypt des-cbc 3482.66k 5069.49k 5496.39k 5614.16k 5639.28k des-cbc 3480.74k 5068.76k 5510.34k 5609.87k 5635.52k des-cbc 3483.72k 5067.62k 5504.60k 5708.01k 5724.80k After: encrypt des-cbc 4660.16k 5650.19k 5807.19k 5827.13k 5783.32k decrypt des-cbc 3624.96k 5258.21k 5530.91k 5624.30k 5628.26k [Ben Laurie] *) Added the OS2-EMX target. ["Brian Havard" and Richard Levitte] *) Rewrite apps to use NCONF routines instead of the old CONF. New functions to support NCONF routines in extension code. New function CONF_set_nconf() to allow functions which take an NCONF to also handle the old LHASH structure: this means that the old CONF compatible routines can be retained (in particular wrt extensions) without having to duplicate the code. New function X509V3_add_ext_nconf_sk to add extensions to a stack. [Steve Henson] *) Enhance the general user interface with mechanisms for inner control and with possibilities to have yes/no kind of prompts. [Richard Levitte] *) Change all calls to low level digest routines in the library and applications to use EVP. Add missing calls to HMAC_cleanup() and don't assume HMAC_CTX can be copied using memcpy(). [Verdon Walker , Steve Henson] *) Add the possibility to control engines through control names but with arbitrary arguments instead of just a string. Change the key loaders to take a UI_METHOD instead of a callback function pointer. NOTE: this breaks binary compatibility with earlier versions of OpenSSL [engine]. Adapt the nCipher code for these new conditions and add a card insertion callback. [Richard Levitte] *) Enhance the general user interface with mechanisms to better support dialog box interfaces, application-defined prompts, the possibility to use defaults (for example default passwords from somewhere else) and interrupts/cancellations. [Richard Levitte] *) Tidy up PKCS#12 attribute handling. Add support for the CSP name attribute in PKCS#12 files, add new -CSP option to pkcs12 utility. [Steve Henson] *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also tidy up some unnecessarily weird code in 'sk_new()'). [Geoff, reported by Diego Tartara ] *) Change the key loading routines for ENGINEs to use the same kind callback (pem_password_cb) as all other routines that need this kind of callback. [Richard Levitte] *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with 256 bit (=32 byte) keys. Of course seeding with more entropy bytes than this minimum value is recommended. [Lutz Jaenicke] *) New random seeder for OpenVMS, using the system process statistics that are easily reachable. [Richard Levitte] *) Windows apparently can't transparently handle global variables defined in DLLs. Initialisations such as: const ASN1_ITEM *it = &ASN1_INTEGER_it; wont compile. This is used by the any applications that need to declare their own ASN1 modules. This was fixed by adding the option EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly needed for static libraries under Win32. [Steve Henson] *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle setting of purpose and trust fields. New X509_STORE trust and purpose functions and tidy up setting in other SSL functions. [Steve Henson] *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE structure. These are inherited by X509_STORE_CTX when it is initialised. This allows various defaults to be set in the X509_STORE structure (such as flags for CRL checking and custom purpose or trust settings) for functions which only use X509_STORE_CTX internally such as S/MIME. Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and trust settings if they are not set in X509_STORE. This allows X509_STORE purposes and trust (in S/MIME for example) to override any set by default. Add command line options for CRL checking to smime, s_client and s_server applications. [Steve Henson] *) Initial CRL based revocation checking. If the CRL checking flag(s) are set then the CRL is looked up in the X509_STORE structure and its validity and signature checked, then if the certificate is found in the CRL the verify fails with a revoked error. Various new CRL related callbacks added to X509_STORE_CTX structure. Command line options added to 'verify' application to support this. This needs some additional work, such as being able to handle multiple CRLs with different times, extension based lookup (rather than just by subject name) and ultimately more complete V2 CRL extension handling. [Steve Henson] *) Add a general user interface API (crypto/ui/). This is designed to replace things like des_read_password and friends (backward compatibility functions using this new API are provided). The purpose is to remove prompting functions from the DES code section as well as provide for prompting through dialog boxes in a window system and the like. [Richard Levitte] *) Add "ex_data" support to ENGINE so implementations can add state at a per-structure level rather than having to store it globally. [Geoff] *) Make it possible for ENGINE structures to be copied when retrieved by ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY. This causes the "original" ENGINE structure to act like a template, analogous to the RSA vs. RSA_METHOD type of separation. Because of this operational state can be localised to each ENGINE structure, despite the fact they all share the same "methods". New ENGINE structures returned in this case have no functional references and the return value is the single structural reference. This matches the single structural reference returned by ENGINE_by_id() normally, when it is incremented on the pre-existing ENGINE structure. [Geoff] *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this needs to match any other type at all we need to manually clear the tag cache. [Steve Henson] *) Changes to the "openssl engine" utility to include; - verbosity levels ('-v', '-vv', and '-vvv') that provide information about an ENGINE's available control commands. - executing control commands from command line arguments using the '-pre' and '-post' switches. '-post' is only used if '-t' is specified and the ENGINE is successfully initialised. The syntax for the individual commands are colon-separated, for example; openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so [Geoff] *) New dynamic control command support for ENGINEs. ENGINEs can now declare their own commands (numbers), names (strings), descriptions, and input types for run-time discovery by calling applications. A subset of these commands are implicitly classed as "executable" depending on their input type, and only these can be invoked through the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this can be based on user input, config files, etc). The distinction is that "executable" commands cannot return anything other than a boolean result and can only support numeric or string input, whereas some discoverable commands may only be for direct use through ENGINE_ctrl(), eg. supporting the exchange of binary data, function pointers, or other custom uses. The "executable" commands are to support parameterisations of ENGINE behaviour that can be unambiguously defined by ENGINEs and used consistently across any OpenSSL-based application. Commands have been added to all the existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow control over shared-library paths without source code alterations. [Geoff] *) Changed all ENGINE implementations to dynamically allocate their ENGINEs rather than declaring them statically. Apart from this being necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction, this also allows the implementations to compile without using the internal engine_int.h header. [Geoff] *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a 'const' value. Any code that should be able to modify a RAND_METHOD should already have non-const pointers to it (ie. they should only modify their own ones). [Geoff] *) Made a variety of little tweaks to the ENGINE code. - "atalla" and "ubsec" string definitions were moved from header files to C code. "nuron" string definitions were placed in variables rather than hard-coded - allowing parameterisation of these values later on via ctrl() commands. - Removed unused "#if 0"'d code. - Fixed engine list iteration code so it uses ENGINE_free() to release structural references. - Constified the RAND_METHOD element of ENGINE structures. - Constified various get/set functions as appropriate and added missing functions (including a catch-all ENGINE_cpy that duplicates all ENGINE values onto a new ENGINE except reference counts/state). - Removed NULL parameter checks in get/set functions. Setting a method or function to NULL is a way of cancelling out a previously set value. Passing a NULL ENGINE parameter is just plain stupid anyway and doesn't justify the extra error symbols and code. - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for flags from engine_int.h to engine.h. - Changed prototypes for ENGINE handler functions (init(), finish(), ctrl(), key-load functions, etc) to take an (ENGINE*) parameter. [Geoff] *) Implement binary inversion algorithm for BN_mod_inverse in addition to the algorithm using long division. The binary algorithm can be used only if the modulus is odd. On 32-bit systems, it is faster only for relatively small moduli (roughly 20-30% for 128-bit moduli, roughly 5-15% for 256-bit moduli), so we use it only for moduli up to 450 bits. In 64-bit environments, the binary algorithm appears to be advantageous for much longer moduli; here we use it for moduli up to 2048 bits. [Bodo Moeller] *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code could not support the combine flag in choice fields. [Steve Henson] *) Add a 'copy_extensions' option to the 'ca' utility. This copies extensions from a certificate request to the certificate. [Steve Henson] *) Allow multiple 'certopt' and 'nameopt' options to be separated by commas. Add 'namopt' and 'certopt' options to the 'ca' config file: this allows the display of the certificate about to be signed to be customised, to allow certain fields to be included or excluded and extension details. The old system didn't display multicharacter strings properly, omitted fields not in the policy and couldn't display additional details such as extensions. [Steve Henson] *) Function EC_POINTs_mul for multiple scalar multiplication of an arbitrary number of elliptic curve points \sum scalars[i]*points[i], optionally including the generator defined for the EC_GROUP: scalar*generator + \sum scalars[i]*points[i]. EC_POINT_mul is a simple wrapper function for the typical case that the point list has just one item (besides the optional generator). [Bodo Moeller] *) First EC_METHODs for curves over GF(p): EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr operations and provides various method functions that can also operate with faster implementations of modular arithmetic. EC_GFp_mont_method() reuses most functions that are part of EC_GFp_simple_method, but uses Montgomery arithmetic. [Bodo Moeller; point addition and point doubling implementation directly derived from source code provided by Lenka Fibikova ] *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h, crypto/ec/ec_lib.c): Curves are EC_GROUP objects (with an optional group generator) based on EC_METHODs that are built into the library. Points are EC_POINT objects based on EC_GROUP objects. Most of the framework would be able to handle curves over arbitrary finite fields, but as there are no obvious types for fields other than GF(p), some functions are limited to that for now. [Bodo Moeller] *) Add the -HTTP option to s_server. It is similar to -WWW, but requires that the file contains a complete HTTP response. [Richard Levitte] *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl change the def and num file printf format specifier from "%-40sXXX" to "%-39s XXX". The latter will always guarantee a space after the field while the former will cause them to run together if the field is 40 of more characters long. [Steve Henson] *) Constify the cipher and digest 'method' functions and structures and modify related functions to take constant EVP_MD and EVP_CIPHER pointers. [Steve Henson] *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them in . Also further increase BN_CTX_NUM to 32. [Bodo Moeller] *) Modify EVP_Digest*() routines so they now return values. Although the internal software routines can never fail additional hardware versions might. [Steve Henson] *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. ASN1 error codes ERR_R_NESTED_ASN1_ERROR ... ERR_R_MISSING_ASN1_EOS were 4 .. 9, conflicting with ERR_LIB_RSA (= ERR_R_RSA_LIB) ... ERR_LIB_PEM (= ERR_R_PEM_LIB). They are now 58 .. 63 (i.e., just below ERR_R_FATAL). Add new error code 'ERR_R_INTERNAL_ERROR'. [Bodo Moeller] *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock suffices. [Bodo Moeller] *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This sets the subject name for a new request or supersedes the subject name in a given request. Formats that can be parsed are 'CN=Some Name, OU=myOU, C=IT' and 'CN=Some Name/OU=myOU/C=IT'. Add options '-batch' and '-verbose' to 'openssl req'. [Massimiliano Pala ] *) Introduce the possibility to access global variables through functions on platform were that's the best way to handle exporting global variables in shared libraries. To enable this functionality, one must configure with "EXPORT_VAR_AS_FN" or defined the C macro "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter is normally done by Configure or something similar). To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL in the source file (foo.c) like this: OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; OPENSSL_IMPLEMENT_GLOBAL(double,bar); To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: OPENSSL_DECLARE_GLOBAL(int,foo); #define foo OPENSSL_GLOBAL_REF(foo) OPENSSL_DECLARE_GLOBAL(double,bar); #define bar OPENSSL_GLOBAL_REF(bar) The #defines are very important, and therefore so is including the header file everywhere where the defined globals are used. The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition of ASN.1 items, but that structure is a bit different. The largest change is in util/mkdef.pl which has been enhanced with better and easier to understand logic to choose which symbols should go into the Windows .def files as well as a number of fixes and code cleanup (among others, algorithm keywords are now sorted lexicographically to avoid constant rewrites). [Richard Levitte] *) In BN_div() keep a copy of the sign of 'num' before writing the result to 'rm' because if rm==num the value will be overwritten and produce the wrong result if 'num' is negative: this caused problems with BN_mod() and BN_nnmod(). [Steve Henson] *) Function OCSP_request_verify(). This checks the signature on an OCSP request and verifies the signer certificate. The signer certificate is just checked for a generic purpose and OCSP request trust settings. [Steve Henson] *) Add OCSP_check_validity() function to check the validity of OCSP responses. OCSP responses are prepared in real time and may only be a few seconds old. Simply checking that the current time lies between thisUpdate and nextUpdate max reject otherwise valid responses caused by either OCSP responder or client clock inaccuracy. Instead we allow thisUpdate and nextUpdate to fall within a certain period of the current time. The age of the response can also optionally be checked. Two new options -validity_period and -status_age added to ocsp utility. [Steve Henson] *) If signature or public key algorithm is unrecognized print out its OID rather that just UNKNOWN. [Steve Henson] *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate ID to be generated from the issuer certificate alone which can then be passed to OCSP_id_issuer_cmp(). [Steve Henson] *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new ASN1 modules to export functions returning ASN1_ITEM pointers instead of the ASN1_ITEM structures themselves. This adds several new macros which allow the underlying ASN1 function/structure to be accessed transparently. As a result code should not use ASN1_ITEM references directly (such as &X509_it) but instead use the relevant macros (such as ASN1_ITEM_rptr(X509)). This option is to allow use of the new ASN1 code on platforms where exporting structures is problematical (for example in shared libraries) but exporting functions returning pointers to structures is not. [Steve Henson] *) Add support for overriding the generation of SSL/TLS session IDs. These callbacks can be registered either in an SSL_CTX or per SSL. The purpose of this is to allow applications to control, if they wish, the arbitrary values chosen for use as session IDs, particularly as it can be useful for session caching in multiple-server environments. A command-line switch for testing this (and any client code that wishes to use such a feature) has been added to "s_server". [Geoff Thorpe, Lutz Jaenicke] *) Modify mkdef.pl to recognise and parse preprocessor conditionals of the form '#if defined(...) || defined(...) || ...' and '#if !defined(...) && !defined(...) && ...'. This also avoids the growing number of special cases it was previously handling. [Richard Levitte] *) Make all configuration macros available for application by making sure they are available in opensslconf.h, by giving them names starting with "OPENSSL_" to avoid conflicts with other packages and by making sure e_os2.h will cover all platform-specific cases together with opensslconf.h. Additionally, it is now possible to define configuration/platform- specific names (called "system identities"). In the C code, these are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another macro with the name beginning with "OPENSSL_SYS_", which is determined from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on what is available. [Richard Levitte] *) New option -set_serial to 'req' and 'x509' this allows the serial number to use to be specified on the command line. Previously self signed certificates were hard coded with serial number 0 and the CA options of 'x509' had to use a serial number in a file which was auto incremented. [Steve Henson] *) New options to 'ca' utility to support V2 CRL entry extensions. Currently CRL reason, invalidity date and hold instruction are supported. Add new CRL extensions to V3 code and some new objects. [Steve Henson] *) New function EVP_CIPHER_CTX_set_padding() this is used to disable standard block padding (aka PKCS#5 padding) in the EVP API, which was previously mandatory. This means that the data is not padded in any way and so the total length much be a multiple of the block size, otherwise an error occurs. [Steve Henson] *) Initial (incomplete) OCSP SSL support. [Steve Henson] *) New function OCSP_parse_url(). This splits up a URL into its host, port and path components: primarily to parse OCSP URLs. New -url option to ocsp utility. [Steve Henson] *) New nonce behavior. The return value of OCSP_check_nonce() now reflects the various checks performed. Applications can decide whether to tolerate certain situations such as an absent nonce in a response when one was present in a request: the ocsp application just prints out a warning. New function OCSP_add1_basic_nonce() this is to allow responders to include a nonce in a response even if the request is nonce-less. [Steve Henson] *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are skipped when using openssl x509 multiple times on a single input file, e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) ] *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates passed by the function are trusted implicitly. If any of them signed the response then it is assumed to be valid and is not verified. [Steve Henson] *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT to data. This was previously part of the PKCS7 ASN1 code. This was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. [Steve Henson, reported by Kenneth R. Robinette ] *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 routines: without these tracing memory leaks is very painful. Fix leaks in PKCS12 and PKCS7 routines. [Steve Henson] *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). Previously it initialised the 'type' argument to V_ASN1_UTCTIME which effectively meant GeneralizedTime would never be used. Now it is initialised to -1 but X509_time_adj() now has to check the value and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. [Steve Henson, reported by Kenneth R. Robinette ] *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously result in a zero length in the ASN1_INTEGER structure which was not consistent with the structure when d2i_ASN1_INTEGER() was used and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() where it did not print out a minus for negative ASN1_INTEGER. [Steve Henson] *) Add summary printout to ocsp utility. The various functions which convert status values to strings have been renamed to: OCSP_response_status_str(), OCSP_cert_status_str() and OCSP_crl_reason_str() and are no longer static. New options to verify nonce values and to disable verification. OCSP response printout format cleaned up. [Steve Henson] *) Add additional OCSP certificate checks. These are those specified in RFC2560. This consists of two separate checks: the CA of the certificate being checked must either be the OCSP signer certificate or the issuer of the OCSP signer certificate. In the latter case the OCSP signer certificate must contain the OCSP signing extended key usage. This check is performed by attempting to match the OCSP signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash in the OCSP_CERTID structures of the response. [Steve Henson] *) Initial OCSP certificate verification added to OCSP_basic_verify() and related routines. This uses the standard OpenSSL certificate verify routines to perform initial checks (just CA validity) and to obtain the certificate chain. Then additional checks will be performed on the chain. Currently the root CA is checked to see if it is explicitly trusted for OCSP signing. This is used to set a root CA as a global signing root: that is any certificate that chains to that CA is an acceptable OCSP signing certificate. [Steve Henson] *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 extensions from a separate configuration file. As when reading extensions from the main configuration file, the '-extensions ...' option may be used for specifying the section to use. [Massimiliano Pala ] *) New OCSP utility. Allows OCSP requests to be generated or read. The request can be sent to a responder and the output parsed, outputed or printed in text form. Not complete yet: still needs to check the OCSP response validity. [Steve Henson] *) New subcommands for 'openssl ca': 'openssl ca -status ' prints the status of the cert with the given serial number (according to the index file). 'openssl ca -updatedb' updates the expiry status of certificates in the index file. [Massimiliano Pala ] *) New '-newreq-nodes' command option to CA.pl. This is like '-newreq', but calls 'openssl req' with the '-nodes' option so that the resulting key is not encrypted. [Damien Miller ] *) New configuration for the GNU Hurd. [Jonathan Bartlett via Richard Levitte] *) Initial code to implement OCSP basic response verify. This is currently incomplete. Currently just finds the signer's certificate and verifies the signature on the response. [Steve Henson] *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in value of OPENSSLDIR. This is available via the new '-d' option to 'openssl version', and is also included in 'openssl version -a'. [Bodo Moeller] *) Allowing defining memory allocation callbacks that will be given file name and line number information in additional arguments (a const char* and an int). The basic functionality remains, as well as the original possibility to just replace malloc(), realloc() and free() by functions that do not know about these additional arguments. To register and find out the current settings for extended allocation functions, the following functions are provided: CRYPTO_set_mem_ex_functions CRYPTO_set_locked_mem_ex_functions CRYPTO_get_mem_ex_functions CRYPTO_get_locked_mem_ex_functions These work the same way as CRYPTO_set_mem_functions and friends. CRYPTO_get_[locked_]mem_functions now writes 0 where such an extended allocation function is enabled. Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where a conventional allocation function is enabled. [Richard Levitte, Bodo Moeller] *) Finish off removing the remaining LHASH function pointer casts. There should no longer be any prototype-casting required when using the LHASH abstraction, and any casts that remain are "bugs". See the callback types and macros at the head of lhash.h for details (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). [Geoff Thorpe] *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. If /dev/[u]random devices are not available or do not return enough entropy, EGD style sockets (served by EGD or PRNGD) will automatically be queried. The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and /etc/entropy will be queried once each in this sequence, quering stops when enough entropy was collected without querying more sockets. [Lutz Jaenicke] *) Change the Unix RAND_poll() variant to be able to poll several random devices, as specified by DEVRANDOM, until a sufficient amount of data has been collected. We spend at most 10 ms on each file (select timeout) and read in non-blocking mode. DEVRANDOM now defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" (previously it was just the string "/dev/urandom"), so on typical platforms the 10 ms delay will never occur. Also separate out the Unix variant to its own file, rand_unix.c. For VMS, there's a currently-empty rand_vms.c. [Richard Levitte] *) Move OCSP client related routines to ocsp_cl.c. These provide utility functions which an application needing to issue a request to an OCSP responder and analyse the response will typically need: as opposed to those which an OCSP responder itself would need which will be added later. OCSP_request_sign() signs an OCSP request with an API similar to PKCS7_sign(). OCSP_response_status() returns status of OCSP response. OCSP_response_get1_basic() extracts basic response from response. OCSP_resp_find_status(): finds and extracts status information from an OCSP_CERTID structure (which will be created when the request structure is built). These are built from lower level functions which work on OCSP_SINGLERESP structures but wont normally be used unless the application wishes to examine extensions in the OCSP response for example. Replace nonce routines with a pair of functions. OCSP_request_add1_nonce() adds a nonce value and optionally generates a random value. OCSP_check_nonce() checks the validity of the nonce in an OCSP response. [Steve Henson] *) Change function OCSP_request_add() to OCSP_request_add0_id(). This doesn't copy the supplied OCSP_CERTID and avoids the need to free up the newly created id. Change return type to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. This can then be used to add extensions to the request. Deleted OCSP_request_new(), since most of its functionality is now in OCSP_REQUEST_new() (and the case insensitive name clash) apart from the ability to set the request name which will be added elsewhere. [Steve Henson] *) Update OCSP API. Remove obsolete extensions argument from various functions. Extensions are now handled using the new OCSP extension code. New simple OCSP HTTP function which can be used to send requests and parse the response. [Steve Henson] *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN uses the special reorder version of SET OF to sort the attributes and reorder them to match the encoded order. This resolves a long standing problem: a verify on a PKCS7 structure just after signing it used to fail because the attribute order did not match the encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: it uses the received order. This is necessary to tolerate some broken software that does not order SET OF. This is handled by encoding as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) to produce the required SET OF. [Steve Henson] *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header files to get correct declarations of the ASN.1 item variables. [Richard Levitte] *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: asn1_check_tlen() would sometimes attempt to use 'ctx' when it was NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant ASN1_ITEM and no wrapper functions. [Steve Henson] *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These replace the old function pointer based I/O routines. Change most of the *_d2i_bio() and *_d2i_fp() functions to use these. [Steve Henson] *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor lines, recognice more "algorithms" that can be deselected, and make it complain about algorithm deselection that isn't recognised. [Richard Levitte] *) New ASN1 functions to handle dup, sign, verify, digest, pack and unpack operations in terms of ASN1_ITEM. Modify existing wrappers to use new functions. Add NO_ASN1_OLD which can be set to remove some old style ASN1 functions: this can be used to determine if old code will still work when these eventually go away. [Steve Henson] *) New extension functions for OCSP structures, these follow the same conventions as certificates and CRLs. [Steve Henson] *) New function X509V3_add1_i2d(). This automatically encodes and adds an extension. Its behaviour can be customised with various flags to append, replace or delete. Various wrappers added for certifcates and CRLs. [Steve Henson] *) Fix to avoid calling the underlying ASN1 print routine when an extension cannot be parsed. Correct a typo in the OCSP_SERVICELOC extension. Tidy up print OCSP format. [Steve Henson] *) Make mkdef.pl parse some of the ASN1 macros and add apropriate entries for variables. [Steve Henson] *) Add functionality to apps/openssl.c for detecting locking problems: As the program is single-threaded, all we have to do is register a locking callback using an array for storing which locks are currently held by the program. [Bodo Moeller] *) Use a lock around the call to CRYPTO_get_ex_new_index() in SSL_get_ex_data_X509_STORE_idx(), which is used in ssl_verify_cert_chain() and thus can be called at any time during TLS/SSL handshakes so that thread-safety is essential. Unfortunately, the ex_data design is not at all suited for multi-threaded use, so it probably should be abolished. [Bodo Moeller] *) Added Broadcom "ubsec" ENGINE to OpenSSL. [Broadcom, tweaked and integrated by Geoff Thorpe] *) Move common extension printing code to new function X509V3_print_extensions(). Reorganise OCSP print routines and implement some needed OCSP ASN1 functions. Add OCSP extensions. [Steve Henson] *) New function X509_signature_print() to remove duplication in some print routines. [Steve Henson] *) Add a special meaning when SET OF and SEQUENCE OF flags are both set (this was treated exactly the same as SET OF previously). This is used to reorder the STACK representing the structure to match the encoding. This will be used to get round a problem where a PKCS7 structure which was signed could not be verified because the STACK order did not reflect the encoded order. [Steve Henson] *) Reimplement the OCSP ASN1 module using the new code. [Steve Henson] *) Update the X509V3 code to permit the use of an ASN1_ITEM structure for its ASN1 operations. The old style function pointers still exist for now but they will eventually go away. [Steve Henson] *) Merge in replacement ASN1 code from the ASN1 branch. This almost completely replaces the old ASN1 functionality with a table driven encoder and decoder which interprets an ASN1_ITEM structure describing the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is largely maintained. Almost all of the old asn1_mac.h macro based ASN1 has also been converted to the new form. [Steve Henson] *) Change BN_mod_exp_recp so that negative moduli are tolerated (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set so that BN_mod_exp_mont and BN_mod_exp_mont_word work for negative moduli. [Bodo Moeller] *) Fix BN_uadd and BN_usub: Always return non-negative results instead of not touching the result's sign bit. [Bodo Moeller] *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be set. [Bodo Moeller] *) Changed the LHASH code to use prototypes for callbacks, and created macros to declare and implement thin (optionally static) functions that provide type-safety and avoid function pointer casting for the type-specific callbacks. [Geoff Thorpe] *) Added Kerberos Cipher Suites to be used with TLS, as written in RFC 2712. [Veers Staats , Jeffrey Altman , via Richard Levitte] *) Reformat the FAQ so the different questions and answers can be divided in sections depending on the subject. [Richard Levitte] *) Have the zlib compression code load ZLIB.DLL dynamically under Windows. [Richard Levitte] *) New function BN_mod_sqrt for computing square roots modulo a prime (using the probabilistic Tonelli-Shanks algorithm unless p == 3 (mod 4) or p == 5 (mod 8), which are cases that can be handled deterministically). [Lenka Fibikova , Bodo Moeller] *) Make BN_mod_inverse faster by explicitly handling small quotients in the Euclid loop. (Speed gain about 20% for small moduli [256 or 512 bits], about 30% for larger ones [1024 or 2048 bits].) [Bodo Moeller] *) New function BN_kronecker. [Bodo Moeller] *) Fix BN_gcd so that it works on negative inputs; the result is positive unless both parameters are zero. Previously something reasonably close to an infinite loop was possible because numbers could be growing instead of shrinking in the implementation of Euclid's algorithm. [Bodo Moeller] *) Fix BN_is_word() and BN_is_one() macros to take into account the sign of the number in question. Fix BN_is_word(a,w) to work correctly for w == 0. The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w) because its test if the absolute value of 'a' equals 'w'. Note that BN_abs_is_word does *not* handle w == 0 reliably; it exists mostly for use in the implementations of BN_is_zero(), BN_is_one(), and BN_is_word(). [Bodo Moeller] *) New function BN_swap. [Bodo Moeller] *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that the exponentiation functions are more likely to produce reasonable results on negative inputs. [Bodo Moeller] *) Change BN_mod_mul so that the result is always non-negative. Previously, it could be negative if one of the factors was negative; I don't think anyone really wanted that behaviour. [Bodo Moeller] *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c (except for exponentiation, which stays in crypto/bn/bn_exp.c, and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c) and add new functions: BN_nnmod BN_mod_sqr BN_mod_add BN_mod_add_quick BN_mod_sub BN_mod_sub_quick BN_mod_lshift1 BN_mod_lshift1_quick BN_mod_lshift BN_mod_lshift_quick These functions always generate non-negative results. BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r such that |m| < r < 0, BN_nnmod will output rem + |m| instead). BN_mod_XXX_quick(r, a, [b,] m) generates the same result as BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b] be reduced modulo m. [Lenka Fibikova , Bodo Moeller] #if 0 The following entry accidentily appeared in the CHANGES file distributed with OpenSSL 0.9.7. The modifications described in it do *not* apply to OpenSSL 0.9.7. *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there was actually never needed) and in BN_mul(). The removal in BN_mul() required a small change in bn_mul_part_recursive() and the addition of the functions bn_cmp_part_words(), bn_sub_part_words() and bn_add_part_words(), which do the same thing as bn_cmp_words(), bn_sub_words() and bn_add_words() except they take arrays with differing sizes. [Richard Levitte] #endif *) In 'openssl passwd', verify passwords read from the terminal unless the '-salt' option is used (which usually means that verification would just waste user's time since the resulting hash is going to be compared with some given password hash) or the new '-noverify' option is used. This is an incompatible change, but it does not affect non-interactive use of 'openssl passwd' (passwords on the command line, '-stdin' option, '-in ...' option) and thus should not cause any problems. [Bodo Moeller] *) Remove all references to RSAref, since there's no more need for it. [Richard Levitte] *) Make DSO load along a path given through an environment variable (SHLIB_PATH) with shl_load(). [Richard Levitte] *) Constify the ENGINE code as a result of BIGNUM constification. Also constify the RSA code and most things related to it. In a few places, most notable in the depth of the ASN.1 code, ugly casts back to non-const were required (to be solved at a later time) [Richard Levitte] *) Make it so the openssl application has all engines loaded by default. [Richard Levitte] *) Constify the BIGNUM routines a little more. [Richard Levitte] *) Add the following functions: ENGINE_load_cswift() ENGINE_load_chil() ENGINE_load_atalla() ENGINE_load_nuron() ENGINE_load_builtin_engines() That way, an application can itself choose if external engines that are built-in in OpenSSL shall ever be used or not. The benefit is that applications won't have to be linked with libdl or other dso libraries unless it's really needed. Changed 'openssl engine' to load all engines on demand. Changed the engine header files to avoid the duplication of some declarations (they differed!). [Richard Levitte] *) 'openssl engine' can now list capabilities. [Richard Levitte] *) Better error reporting in 'openssl engine'. [Richard Levitte] *) Never call load_dh_param(NULL) in s_server. [Bodo Moeller] *) Add engine application. It can currently list engines by name and identity, and test if they are actually available. [Richard Levitte] *) Improve RPM specification file by forcing symbolic linking and making sure the installed documentation is also owned by root.root. [Damien Miller ] *) Give the OpenSSL applications more possibilities to make use of keys (public as well as private) handled by engines. [Richard Levitte] *) Add OCSP code that comes from CertCo. [Richard Levitte] *) Add VMS support for the Rijndael code. [Richard Levitte] *) Added untested support for Nuron crypto accelerator. [Ben Laurie] *) Add support for external cryptographic devices. This code was previously distributed separately as the "engine" branch. [Geoff Thorpe, Richard Levitte] *) Rework the filename-translation in the DSO code. It is now possible to have far greater control over how a "name" is turned into a filename depending on the operating environment and any oddities about the different shared library filenames on each system. [Geoff Thorpe] *) Support threads on FreeBSD-elf in Configure. [Richard Levitte] *) Fix for SHA1 assembly problem with MASM: it produces warnings about corrupt line number information when assembling with debugging information. This is caused by the overlapping of two sections. [Bernd Matthes , Steve Henson] *) NCONF changes. NCONF_get_number() has no error checking at all. As a replacement, NCONF_get_number_e() is defined (_e for "error checking") and is promoted strongly. The old NCONF_get_number is kept around for binary backward compatibility. Make it possible for methods to load from something other than a BIO, by providing a function pointer that is given a name instead of a BIO. For example, this could be used to load configuration data from an LDAP server. [Richard Levitte] *) Fix for non blocking accept BIOs. Added new I/O special reason BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs with non blocking I/O was not possible because no retry code was implemented. Also added new SSL code SSL_WANT_ACCEPT to cover this case. [Steve Henson] *) Added the beginnings of Rijndael support. [Ben Laurie] *) Fix for bug in DirectoryString mask setting. Add support for X509_NAME_print_ex() in 'req' and X509_print_ex() function to allow certificate printing to more controllable, additional 'certopt' option to 'x509' to allow new printing options to be set. [Steve Henson] *) Clean old EAY MD5 hack from e_os.h. [Richard Levitte] Changes between 0.9.6l and 0.9.6m [17 Mar 2004] *) Fix null-pointer assignment in do_change_cipher_spec() revealed by using the Codenomicon TLS Test Tool (CVE-2004-0079) [Joe Orton, Steve Henson] Changes between 0.9.6k and 0.9.6l [04 Nov 2003] *) Fix additional bug revealed by the NISCC test suite: Stop bug triggering large recursion when presented with certain ASN.1 tags (CVE-2003-0851) [Steve Henson] Changes between 0.9.6j and 0.9.6k [30 Sep 2003] *) Fix various bugs revealed by running the NISCC test suite: Stop out of bounds reads in the ASN1 code when presented with invalid tags (CVE-2003-0543 and CVE-2003-0544). If verify callback ignores invalid public key errors don't try to check certificate signature with the NULL public key. [Steve Henson] *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate if the server requested one: as stated in TLS 1.0 and SSL 3.0 specifications. [Steve Henson] *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional extra data after the compression methods not only for TLS 1.0 but also for SSL 3.0 (as required by the specification). [Bodo Moeller; problem pointed out by Matthias Loepfe] *) Change X509_certificate_type() to mark the key as exported/exportable when it's 512 *bits* long, not 512 bytes. [Richard Levitte] Changes between 0.9.6i and 0.9.6j [10 Apr 2003] *) Countermeasure against the Klima-Pokorny-Rosa extension of Bleichbacher's attack on PKCS #1 v1.5 padding: treat a protocol version number mismatch like a decryption error in ssl3_get_client_key_exchange (ssl/s3_srvr.c). [Bodo Moeller] *) Turn on RSA blinding by default in the default implementation to avoid a timing attack. Applications that don't want it can call RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING. They would be ill-advised to do so in most cases. [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller] *) Change RSA blinding code so that it works when the PRNG is not seeded (in this case, the secret RSA exponent is abused as an unpredictable seed -- if it is not unpredictable, there is no point in blinding anyway). Make RSA blinding thread-safe by remembering the creator's thread ID in rsa->blinding and having all other threads use local one-time blinding factors (this requires more computation than sharing rsa->blinding, but avoids excessive locking; and if an RSA object is not shared between threads, blinding will still be very fast). [Bodo Moeller] Changes between 0.9.6h and 0.9.6i [19 Feb 2003] *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked via timing by performing a MAC computation even if incorrrect block cipher padding has been found. This is a countermeasure against active attacks where the attacker has to distinguish between bad padding and a MAC verification error. (CVE-2003-0078) [Bodo Moeller; problem pointed out by Brice Canvel (EPFL), Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and Martin Vuagnoux (EPFL, Ilion)] Changes between 0.9.6g and 0.9.6h [5 Dec 2002] *) New function OPENSSL_cleanse(), which is used to cleanse a section of memory from it's contents. This is done with a counter that will place alternating values in each byte. This can be used to solve two issues: 1) the removal of calls to memset() by highly optimizing compilers, and 2) cleansing with other values than 0, since those can be read through on certain media, for example a swap space on disk. [Geoff Thorpe] *) Bugfix: client side session caching did not work with external caching, because the session->cipher setting was not restored when reloading from the external cache. This problem was masked, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set. (Found by Steve Haslam .) [Lutz Jaenicke] *) Fix client_certificate (ssl/s2_clnt.c): The permissible total length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33. [Zeev Lieber ] *) Undo an undocumented change introduced in 0.9.6e which caused repeated calls to OpenSSL_add_all_ciphers() and OpenSSL_add_all_digests() to be ignored, even after calling EVP_cleanup(). [Richard Levitte] *) Change the default configuration reader to deal with last line not being properly terminated. [Richard Levitte] *) Change X509_NAME_cmp() so it applies the special rules on handling DN values that are of type PrintableString, as well as RDNs of type emailAddress where the value has the type ia5String. [stefank@valicert.com via Richard Levitte] *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be the bitwise-OR of the two for use by the majority of applications wanting this behaviour, and update the docs. The documented behaviour and actual behaviour were inconsistent and had been changing anyway, so this is more a bug-fix than a behavioural change. [Geoff Thorpe, diagnosed by Nadav Har'El] *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes). [Bodo Moeller] *) Fix initialization code race conditions in SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(), SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(), SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(), TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(), ssl2_get_cipher_by_char(), ssl3_get_cipher_by_char(). [Patrick McCormick , Bodo Moeller] *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after the cached sessions are flushed, as the remove_cb() might use ex_data contents. Bug found by Sam Varshavchik (see [openssl.org #212]). [Geoff Thorpe, Lutz Jaenicke] *) Fix typo in OBJ_txt2obj which incorrectly passed the content length, instead of the encoding length to d2i_ASN1_OBJECT. [Steve Henson] Changes between 0.9.6f and 0.9.6g [9 Aug 2002] *) [In 0.9.6g-engine release:] Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall'). [Lynn Gazis ] Changes between 0.9.6e and 0.9.6f [8 Aug 2002] *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX and get fix the header length calculation. [Florian Weimer , Alon Kantor (and others), Steve Henson] *) Use proper error handling instead of 'assertions' in buffer overflow checks added in 0.9.6e. This prevents DoS (the assertions could call abort()). [Arne Ansper , Bodo Moeller] Changes between 0.9.6d and 0.9.6e [30 Jul 2002] *) Add various sanity checks to asn1_get_length() to reject the ASN1 length bytes if they exceed sizeof(long), will appear negative or the content length exceeds the length of the supplied buffer. [Steve Henson, Adi Stav , James Yonan ] *) Fix cipher selection routines: ciphers without encryption had no flags for the cipher strength set and where therefore not handled correctly by the selection routines (PR #130). [Lutz Jaenicke] *) Fix EVP_dsa_sha macro. [Nils Larsch] *) New option SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure that was added in OpenSSL 0.9.6d. As the countermeasure turned out to be incompatible with some broken SSL implementations, the new option is part of SSL_OP_ALL. SSL_OP_ALL is usually employed when compatibility with weird SSL implementations is desired (e.g. '-bugs' option to 's_client' and 's_server'), so the new option is automatically set in many applications. [Bodo Moeller] *) Changes in security patch: Changes marked "(CHATS)" were sponsored by the Defense Advanced Research Projects Agency (DARPA) and Air Force Research Laboratory, Air Force Materiel Command, USAF, under agreement number F30602-01-2-0537. *) Add various sanity checks to asn1_get_length() to reject the ASN1 length bytes if they exceed sizeof(long), will appear negative or the content length exceeds the length of the supplied buffer. (CVE-2002-0659) [Steve Henson, Adi Stav , James Yonan ] *) Assertions for various potential buffer overflows, not known to happen in practice. [Ben Laurie (CHATS)] *) Various temporary buffers to hold ASCII versions of integers were too small for 64 bit platforms. (CVE-2002-0655) [Matthew Byng-Maddick and Ben Laurie (CHATS)> *) Remote buffer overflow in SSL3 protocol - an attacker could supply an oversized session ID to a client. (CVE-2002-0656) [Ben Laurie (CHATS)] *) Remote buffer overflow in SSL2 protocol - an attacker could supply an oversized client master key. (CVE-2002-0656) [Ben Laurie (CHATS)] Changes between 0.9.6c and 0.9.6d [9 May 2002] *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not encoded as NULL) with id-dsa-with-sha1. [Nils Larsch ; problem pointed out by Bodo Moeller] *) Check various X509_...() return values in apps/req.c. [Nils Larsch ] *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines: an end-of-file condition would erronously be flagged, when the CRLF was just at the end of a processed block. The bug was discovered when processing data through a buffering memory BIO handing the data to a BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov and Nedelcho Stanev. [Lutz Jaenicke] *) Implement a countermeasure against a vulnerability recently found in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment before application data chunks to avoid the use of known IVs with data potentially chosen by the attacker. [Bodo Moeller] *) Fix length checks in ssl3_get_client_hello(). [Bodo Moeller] *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently to prevent ssl3_read_internal() from incorrectly assuming that ssl3_read_bytes() found application data while handshake processing was enabled when in fact s->s3->in_read_app_data was merely automatically cleared during the initial handshake. [Bodo Moeller; problem pointed out by Arne Ansper ] *) Fix object definitions for Private and Enterprise: they were not recognized in their shortname (=lowercase) representation. Extend obj_dat.pl to issue an error when using undefined keywords instead of silently ignoring the problem (Svenning Sorensen ). [Lutz Jaenicke] *) Fix DH_generate_parameters() so that it works for 'non-standard' generators, i.e. generators other than 2 and 5. (Previously, the code did not properly initialise the 'add' and 'rem' values to BN_generate_prime().) In the new general case, we do not insist that 'generator' is actually a primitive root: This requirement is rather pointless; a generator of the order-q subgroup is just as good, if not better. [Bodo Moeller] *) Map new X509 verification errors to alerts. Discovered and submitted by Tom Wu . [Lutz Jaenicke] *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from returning non-zero before the data has been completely received when using non-blocking I/O. [Bodo Moeller; problem pointed out by John Hughes] *) Some of the ciphers missed the strength entry (SSL_LOW etc). [Ben Laurie, Lutz Jaenicke] *) Fix bug in SSL_clear(): bad sessions were not removed (found by Yoram Zahavi ). [Lutz Jaenicke] *) Add information about CygWin 1.3 and on, and preserve proper configuration for the versions before that. [Corinna Vinschen and Richard Levitte] *) Make removal from session cache (SSL_CTX_remove_session()) more robust: check whether we deal with a copy of a session and do not delete from the cache in this case. Problem reported by "Izhar Shoshani Levi" . [Lutz Jaenicke] *) Do not store session data into the internal session cache, if it is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP flag is set). Proposed by Aslam . [Lutz Jaenicke] *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested value is 0. [Richard Levitte] *) [In 0.9.6d-engine release:] Fix a crashbug and a logic bug in hwcrhk_load_pubkey(). [Toomas Kiisk via Richard Levitte] *) Add the configuration target linux-s390x. [Neale Ferguson via Richard Levitte] *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag variable as an indication that a ClientHello message has been received. As the flag value will be lost between multiple invocations of ssl3_accept when using non-blocking I/O, the function may not be aware that a handshake has actually taken place, thus preventing a new session from being added to the session cache. To avoid this problem, we now set s->new_session to 2 instead of using a local variable. [Lutz Jaenicke, Bodo Moeller] *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c) if the SSL_R_LENGTH_MISMATCH error is detected. [Geoff Thorpe, Bodo Moeller] *) New 'shared_ldflag' column in Configure platform table. [Richard Levitte] *) Fix EVP_CIPHER_mode macro. ["Dan S. Camper" ] *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown type, we must throw them away by setting rr->length to 0. [D P Chang ] Changes between 0.9.6b and 0.9.6c [21 dec 2001] *) Fix BN_rand_range bug pointed out by Dominikus Scherkl . (The previous implementation worked incorrectly for those cases where range = 10..._2 and 3*range is two bits longer than range.) [Bodo Moeller] *) Only add signing time to PKCS7 structures if it is not already present. [Steve Henson] *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce", OBJ_ld_ce should be OBJ_id_ce. Also some ip-pda OIDs in crypto/objects/objects.txt were incorrect (cf. RFC 3039). [Matt Cooper, Frederic Giudicelli, Bodo Moeller] *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid() returns early because it has nothing to do. [Andy Schneider ] *) [In 0.9.6c-engine release:] Fix mutex callback return values in crypto/engine/hw_ncipher.c. [Andy Schneider ] *) [In 0.9.6c-engine release:] Add support for Cryptographic Appliance's keyserver technology. (Use engine 'keyclient') [Cryptographic Appliances and Geoff Thorpe] *) Add a configuration entry for OS/390 Unix. The C compiler 'c89' is called via tools/c89.sh because arguments have to be rearranged (all '-L' options must appear before the first object modules). [Richard Shapiro ] *) [In 0.9.6c-engine release:] Add support for Broadcom crypto accelerator cards, backported from 0.9.7. [Broadcom, Nalin Dahyabhai , Mark Cox] *) [In 0.9.6c-engine release:] Add support for SureWare crypto accelerator cards from Baltimore Technologies. (Use engine 'sureware') [Baltimore Technologies and Mark Cox] *) [In 0.9.6c-engine release:] Add support for crypto accelerator cards from Accelerated Encryption Processing, www.aep.ie. (Use engine 'aep') [AEP Inc. and Mark Cox] *) Add a configuration entry for gcc on UnixWare. [Gary Benson ] *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake messages are stored in a single piece (fixed-length part and variable-length part combined) and fix various bugs found on the way. [Bodo Moeller] *) Disable caching in BIO_gethostbyname(), directly use gethostbyname() instead. BIO_gethostbyname() does not know what timeouts are appropriate, so entries would stay in cache even when they have become invalid. [Bodo Moeller; problem pointed out by Rich Salz *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when faced with a pathologically small ClientHello fragment that does not contain client_version: Instead of aborting with an error, simply choose the highest available protocol version (i.e., TLS 1.0 unless it is disabled). In practice, ClientHello messages are never sent like this, but this change gives us strictly correct behaviour at least for TLS. [Bodo Moeller] *) Fix SSL handshake functions and SSL_clear() such that SSL_clear() never resets s->method to s->ctx->method when called from within one of the SSL handshake functions. [Bodo Moeller; problem pointed out by Niko Baric] *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert (sent using the client's version number) if client_version is smaller than the protocol version in use. Also change ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if the client demanded SSL 3.0 but only TLS 1.0 is enabled; then the client will at least see that alert. [Bodo Moeller] *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation correctly. [Bodo Moeller] *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a client receives HelloRequest while in a handshake. [Bodo Moeller; bug noticed by Andy Schneider ] *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C should end in 'break', not 'goto end' which circuments various cleanups done in state SSL_ST_OK. But session related stuff must be disabled for SSL_ST_OK in the case that we just sent a HelloRequest. Also avoid some overhead by not calling ssl_init_wbio_buffer() before just sending a HelloRequest. [Bodo Moeller, Eric Rescorla ] *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't reveal whether illegal block cipher padding was found or a MAC verification error occured. (Neither SSLerr() codes nor alerts are directly visible to potential attackers, but the information may leak via logfiles.) Similar changes are not required for the SSL 2.0 implementation because the number of padding bytes is sent in clear for SSL 2.0, and the extra bytes are just ignored. However ssl/s2_pkt.c failed to verify that the purported number of padding bytes is in the legal range. [Bodo Moeller] *) Add OpenUNIX-8 support including shared libraries (Boyd Lynn Gerber ). [Lutz Jaenicke] *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid 'wristwatch attack' using huge encoding parameters (cf. James H. Manger's CRYPTO 2001 paper). Note that the RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use encoding parameters and hence was not vulnerable. [Bodo Moeller] *) BN_sqr() bug fix. [Ulf Möller, reported by Jim Ellis ] *) Rabin-Miller test analyses assume uniformly distributed witnesses, so use BN_pseudo_rand_range() instead of using BN_pseudo_rand() followed by modular reduction. [Bodo Moeller; pointed out by Adam Young ] *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range() equivalent based on BN_pseudo_rand() instead of BN_rand(). [Bodo Moeller] *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB). This function was broken, as the check for a new client hello message to handle SGC did not allow these large messages. (Tracked down by "Douglas E. Engert" .) [Lutz Jaenicke] *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long](). [Lutz Jaenicke] *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl() for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" ). [Lutz Jaenicke] *) Rework the configuration and shared library support for Tru64 Unix. The configuration part makes use of modern compiler features and still retains old compiler behavior for those that run older versions of the OS. The shared library support part includes a variant that uses the RPATH feature, and is available through the special configuration target "alpha-cc-rpath", which will never be selected automatically. [Tim Mooney via Richard Levitte] *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message() with the same message size as in ssl3_get_certificate_request(). Otherwise, if no ServerKeyExchange message occurs, CertificateRequest messages might inadvertently be reject as too long. [Petr Lampa ] *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX). [Andy Polyakov] *) Modified SSL library such that the verify_callback that has been set specificly for an SSL object with SSL_set_verify() is actually being used. Before the change, a verify_callback set with this function was ignored and the verify_callback() set in the SSL_CTX at the time of the call was used. New function X509_STORE_CTX_set_verify_cb() introduced to allow the necessary settings. [Lutz Jaenicke] *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c explicitly to NULL, as at least on Solaris 8 this seems not always to be done automatically (in contradiction to the requirements of the C standard). This made problems when used from OpenSSH. [Lutz Jaenicke] *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored dh->length and always used BN_rand_range(priv_key, dh->p). BN_rand_range() is not necessary for Diffie-Hellman, and this specific range makes Diffie-Hellman unnecessarily inefficient if dh->length (recommended exponent length) is much smaller than the length of dh->p. We could use BN_rand_range() if the order of the subgroup was stored in the DH structure, but we only have dh->length. So switch back to BN_rand(priv_key, l, ...) where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1 otherwise. [Bodo Moeller] *) In RSA_eay_public_encrypt RSA_eay_private_decrypt RSA_eay_private_encrypt (signing) RSA_eay_public_decrypt (signature verification) (default implementations for RSA_public_encrypt, RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt), always reject numbers >= n. [Bodo Moeller] *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2 to synchronize access to 'locking_thread'. This is necessary on systems where access to 'locking_thread' (an 'unsigned long' variable) is not atomic. [Bodo Moeller] *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID *before* setting the 'crypto_lock_rand' flag. The previous code had a race condition if 0 is a valid thread ID. [Travis Vitek ] *) Add support for shared libraries under Irix. [Albert Chin-A-Young ] *) Add configuration option to build on Linux on both big-endian and little-endian MIPS. [Ralf Baechle ] *) Add the possibility to create shared libraries on HP-UX. [Richard Levitte] Changes between 0.9.6a and 0.9.6b [9 Jul 2001] *) Change ssleay_rand_bytes (crypto/rand/md_rand.c) to avoid a SSLeay/OpenSSL PRNG weakness pointed out by Markku-Juhani O. Saarinen : PRNG state recovery was possible based on the output of one PRNG request appropriately sized to gain knowledge on 'md' followed by enough consecutive 1-byte PRNG requests to traverse all of 'state'. 1. When updating 'md_local' (the current thread's copy of 'md') during PRNG output generation, hash all of the previous 'md_local' value, not just the half used for PRNG output. 2. Make the number of bytes from 'state' included into the hash independent from the number of PRNG bytes requested. The first measure alone would be sufficient to avoid Markku-Juhani's attack. (Actually it had never occurred to me that the half of 'md_local' used for chaining was the half from which PRNG output bytes were taken -- I had always assumed that the secret half would be used.) The second measure makes sure that additional data from 'state' is never mixed into 'md_local' in small portions; this heuristically further strengthens the PRNG. [Bodo Moeller] *) Fix crypto/bn/asm/mips3.s. [Andy Polyakov] *) When only the key is given to "enc", the IV is undefined. Print out an error message in this case. [Lutz Jaenicke] *) Handle special case when X509_NAME is empty in X509 printing routines. [Steve Henson] *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are positive and less than q. [Bodo Moeller] *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is used: it isn't thread safe and the add_lock_callback should handle that itself. [Paul Rose ] *) Verify that incoming data obeys the block size in ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c). [Bodo Moeller] *) Fix OAEP check. [Ulf Möller, Bodo Möller] *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5 when fixing the server behaviour for backwards-compatible 'client hello' messages. (Note that the attack is impractical against SSL 3.0 and TLS 1.0 anyway because length and version checking means that the probability of guessing a valid ciphertext is around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98 paper.) Before 0.9.5, the countermeasure (hide the error by generating a random 'decryption result') did not work properly because ERR_clear_error() was missing, meaning that SSL_get_error() would detect the supposedly ignored error. Both problems are now fixed. [Bodo Moeller] *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096 (previously it was 1024). [Bodo Moeller] *) Fix for compatibility mode trust settings: ignore trust settings unless some valid trust or reject settings are present. [Steve Henson] *) Fix for blowfish EVP: its a variable length cipher. [Steve Henson] *) Fix various bugs related to DSA S/MIME verification. Handle missing parameters in DSA public key structures and return an error in the DSA routines if parameters are absent. [Steve Henson] *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd" in the current directory if neither $RANDFILE nor $HOME was set. RAND_file_name() in 0.9.6a returned NULL in this case. This has caused some confusion to Windows users who haven't defined $HOME. Thus RAND_file_name() is changed again: e_os.h can define a DEFAULT_HOME, which will be used if $HOME is not set. For Windows, we use "C:"; on other platforms, we still require environment variables. *) Move 'if (!initialized) RAND_poll()' into regions protected by CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids having multiple threads call RAND_poll() concurrently. [Bodo Moeller] *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a combination of a flag and a thread ID variable. Otherwise while one thread is in ssleay_rand_bytes (which sets the flag), *other* threads can enter ssleay_add_bytes without obeying the CRYPTO_LOCK_RAND lock (and may even illegally release the lock that they do not hold after the first thread unsets add_do_not_lock). [Bodo Moeller] *) Change bctest again: '-x' expressions are not available in all versions of 'test'. [Bodo Moeller] Changes between 0.9.6 and 0.9.6a [5 Apr 2001] *) Fix a couple of memory leaks in PKCS7_dataDecode() [Steve Henson, reported by Heyun Zheng ] *) Change Configure and Makefiles to provide EXE_EXT, which will contain the default extension for executables, if any. Also, make the perl scripts that use symlink() to test if it really exists and use "cp" if it doesn't. All this made OpenSSL compilable and installable in CygWin. [Richard Levitte] *) Fix for asn1_GetSequence() for indefinite length constructed data. If SEQUENCE is length is indefinite just set c->slen to the total amount of data available. [Steve Henson, reported by shige@FreeBSD.org] [This change does not apply to 0.9.7.] *) Change bctest to avoid here-documents inside command substitution (workaround for FreeBSD /bin/sh bug). For compatibility with Ultrix, avoid shell functions (introduced in the bctest version that searches along $PATH). [Bodo Moeller] *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes with des_encrypt() defined on some operating systems, like Solaris and UnixWare. [Richard Levitte] *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton: On the Importance of Eliminating Errors in Cryptographic Computations, J. Cryptology 14 (2001) 2, 101-119, http://theory.stanford.edu/~dabo/papers/faults.ps.gz). [Ulf Moeller] *) MIPS assembler BIGNUM division bug fix. [Andy Polyakov] *) Disabled incorrect Alpha assembler code. [Richard Levitte] *) Fix PKCS#7 decode routines so they correctly update the length after reading an EOC for the EXPLICIT tag. [Steve Henson] [This change does not apply to 0.9.7.] *) Fix bug in PKCS#12 key generation routines. This was triggered if a 3DES key was generated with a 0 initial byte. Include PKCS12_BROKEN_KEYGEN compilation option to retain the old (but broken) behaviour. [Steve Henson] *) Enhance bctest to search for a working bc along $PATH and print it when found. [Tim Rice via Richard Levitte] *) Fix memory leaks in err.c: free err_data string if necessary; don't write to the wrong index in ERR_set_error_data. [Bodo Moeller] *) Implement ssl23_peek (analogous to ssl23_read), which previously did not exist. [Bodo Moeller] *) Replace rdtsc with _emit statements for VC++ version 5. [Jeremy Cooper ] *) Make it possible to reuse SSLv2 sessions. [Richard Levitte] *) In copy_email() check for >= 0 as a return value for X509_NAME_get_index_by_NID() since 0 is a valid index. [Steve Henson reported by Massimiliano Pala ] *) Avoid coredump with unsupported or invalid public keys by checking if X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when PKCS7_verify() fails with non detached data. [Steve Henson] *) Don't use getenv in library functions when run as setuid/setgid. New function OPENSSL_issetugid(). [Ulf Moeller] *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c) due to incorrect handling of multi-threading: 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl(). 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on(). 3. Count how many times MemCheck_off() has been called so that nested use can be treated correctly. This also avoids inband-signalling in the previous code (which relied on the assumption that thread ID 0 is impossible). [Bodo Moeller] *) Add "-rand" option also to s_client and s_server. [Lutz Jaenicke] *) Fix CPU detection on Irix 6.x. [Kurt Hockenbury and "Bruce W. Forsberg" ] *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME was empty. [Steve Henson] [This change does not apply to 0.9.7.] *) Use the cached encoding of an X509_NAME structure rather than copying it. This is apparently the reason for the libsafe "errors" but the code is actually correct. [Steve Henson] *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent Bleichenbacher's DSA attack. Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits to be set and top=0 forces the highest bit to be set; top=-1 is new and leaves the highest bit random. [Ulf Moeller, Bodo Moeller] *) In the NCONF_...-based implementations for CONF_... queries (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using a temporary CONF structure with the data component set to NULL (which gives segmentation faults in lh_retrieve). Instead, use NULL for the CONF pointer in CONF_get_string and CONF_get_number (which may use environment variables) and directly return NULL from CONF_get_section. [Bodo Moeller] *) Fix potential buffer overrun for EBCDIC. [Ulf Moeller] *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign keyUsage if basicConstraints absent for a CA. [Steve Henson] *) Make SMIME_write_PKCS7() write mail header values with a format that is more generally accepted (no spaces before the semicolon), since some programs can't parse those values properly otherwise. Also make sure BIO's that break lines after each write do not create invalid headers. [Richard Levitte] *) Make the CRL encoding routines work with empty SEQUENCE OF. The macros previously used would not encode an empty SEQUENCE OF and break the signature. [Steve Henson] [This change does not apply to 0.9.7.] *) Zero the premaster secret after deriving the master secret in DH ciphersuites. [Steve Henson] *) Add some EVP_add_digest_alias registrations (as found in OpenSSL_add_all_digests()) to SSL_library_init() aka OpenSSL_add_ssl_algorithms(). This provides improved compatibility with peers using X.509 certificates with unconventional AlgorithmIdentifier OIDs. [Bodo Moeller] *) Fix for Irix with NO_ASM. ["Bruce W. Forsberg" ] *) ./config script fixes. [Ulf Moeller, Richard Levitte] *) Fix 'openssl passwd -1'. [Bodo Moeller] *) Change PKCS12_key_gen_asc() so it can cope with non null terminated strings whose length is passed in the passlen parameter, for example from PEM callbacks. This was done by adding an extra length parameter to asc2uni(). [Steve Henson, reported by ] *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn call failed, free the DSA structure. [Bodo Moeller] *) Fix to uni2asc() to cope with zero length Unicode strings. These are present in some PKCS#12 files. [Steve Henson] *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits when writing a 32767 byte record. [Bodo Moeller; problem reported by Eric Day ] *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. (RSA objects have a reference count access to which is protected by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], so they are meant to be shared between threads.) [Bodo Moeller, Geoff Thorpe; original patch submitted by "Reddie, Steven" ] *) Fix a deadlock in CRYPTO_mem_leaks(). [Bodo Moeller] *) Use better test patterns in bntest. [Ulf Möller] *) rand_win.c fix for Borland C. [Ulf Möller] *) BN_rshift bugfix for n == 0. [Bodo Moeller] *) Add a 'bctest' script that checks for some known 'bc' bugs so that 'make test' does not abort just because 'bc' is broken. [Bodo Moeller] *) Store verify_result within SSL_SESSION also for client side to avoid potential security hole. (Re-used sessions on the client side always resulted in verify_result==X509_V_OK, not using the original result of the server certificate verification.) [Lutz Jaenicke] *) Fix ssl3_pending: If the record in s->s3->rrec is not of type SSL3_RT_APPLICATION_DATA, return 0. Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true. [Bodo Moeller] *) Fix SSL_peek: Both ssl2_peek and ssl3_peek, which were totally broken in earlier releases, have been re-implemented by renaming the previous implementations of ssl2_read and ssl3_read to ssl2_read_internal and ssl3_read_internal, respectively, and adding 'peek' parameters to them. The new ssl[23]_{read,peek} functions are calls to ssl[23]_read_internal with the 'peek' flag set appropriately. A 'peek' parameter has also been added to ssl3_read_bytes, which does the actual work for ssl3_read_internal. [Bodo Moeller] *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling the method-specific "init()" handler. Also clean up ex_data after calling the method-specific "finish()" handler. Previously, this was happening the other way round. [Geoff Thorpe] *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16. The previous value, 12, was not always sufficient for BN_mod_exp(). [Bodo Moeller] *) Make sure that shared libraries get the internal name engine with the full version number and not just 0. This should mark the shared libraries as not backward compatible. Of course, this should be changed again when we can guarantee backward binary compatibility. [Richard Levitte] *) Fix typo in get_cert_by_subject() in by_dir.c [Jean-Marc Desperrier ] *) Rework the system to generate shared libraries: - Make note of the expected extension for the shared libraries and if there is a need for symbolic links from for example libcrypto.so.0 to libcrypto.so.0.9.7. There is extended info in Configure for that. - Make as few rebuilds of the shared libraries as possible. - Still avoid linking the OpenSSL programs with the shared libraries. - When installing, install the shared libraries separately from the static ones. [Richard Levitte] *) Fix SSL_CTX_set_read_ahead macro to actually use its argument. Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new and not in SSL_clear because the latter is also used by the accept/connect functions; previously, the settings made by SSL_set_read_ahead would be lost during the handshake. [Bodo Moeller; problems reported by Anders Gertz ] *) Correct util/mkdef.pl to be selective about disabled algorithms. Previously, it would create entries for disableed algorithms no matter what. [Richard Levitte] *) Added several new manual pages for SSL_* function. [Lutz Jaenicke] Changes between 0.9.5a and 0.9.6 [24 Sep 2000] *) In ssl23_get_client_hello, generate an error message when faced with an initial SSL 3.0/TLS record that is too small to contain the first two bytes of the ClientHello message, i.e. client_version. (Note that this is a pathologic case that probably has never happened in real life.) The previous approach was to use the version number from the record header as a substitute; but our protocol choice should not depend on that one because it is not authenticated by the Finished messages. [Bodo Moeller] *) More robust randomness gathering functions for Windows. [Jeffrey Altman ] *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is not set then we don't setup the error code for issuer check errors to avoid possibly overwriting other errors which the callback does handle. If an application does set the flag then we assume it knows what it is doing and can handle the new informational codes appropriately. [Steve Henson] *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for a general "ANY" type, as such it should be able to decode anything including tagged types. However it didn't check the class so it would wrongly interpret tagged types in the same way as their universal counterpart and unknown types were just rejected. Changed so that the tagged and unknown types are handled in the same way as a SEQUENCE: that is the encoding is stored intact. There is also a new type "V_ASN1_OTHER" which is used when the class is not universal, in this case we have no idea what the actual type is so we just lump them all together. [Steve Henson] *) On VMS, stdout may very well lead to a file that is written to in a record-oriented fashion. That means that every write() will write a separate record, which will be read separately by the programs trying to read from it. This can be very confusing. The solution is to put a BIO filter in the way that will buffer text until a linefeed is reached, and then write everything a line at a time, so every record written will be an actual line, not chunks of lines and not (usually doesn't happen, but I've seen it once) several lines in one record. BIO_f_linebuffer() is the answer. Currently, it's a VMS-only method, because that's where it has been tested well enough. [Richard Levitte] *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery, it can return incorrect results. (Note: The buggy variant was not enabled in OpenSSL 0.9.5a, but it was in 0.9.6-beta[12].) [Bodo Moeller] *) Disable the check for content being present when verifying detached signatures in pk7_smime.c. Some versions of Netscape (wrongly) include zero length content when signing messages. [Steve Henson] *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR BIO_ctrl (for BIO pairs). [Bodo Möller] *) Add DSO method for VMS. [Richard Levitte] *) Bug fix: Montgomery multiplication could produce results with the wrong sign. [Ulf Möller] *) Add RPM specification openssl.spec and modify it to build three packages. The default package contains applications, application documentation and run-time libraries. The devel package contains include files, static libraries and function documentation. The doc package contains the contents of the doc directory. The original openssl.spec was provided by Damien Miller . [Richard Levitte] *) Add a large number of documentation files for many SSL routines. [Lutz Jaenicke ] *) Add a configuration entry for Sony News 4. [NAKAJI Hiroyuki ] *) Don't set the two most significant bits to one when generating a random number < q in the DSA library. [Ulf Möller] *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if the underlying transport is blocking) if a handshake took place. (The default behaviour is needed by applications such as s_client and s_server that use select() to determine when to use SSL_read; but for applications that know in advance when to expect data, it just makes things more complicated.) [Bodo Moeller] *) Add RAND_egd_bytes(), which gives control over the number of bytes read from EGD. [Ben Laurie] *) Add a few more EBCDIC conditionals that make `req' and `x509' work better on such systems. [Martin Kraemer ] *) Add two demo programs for PKCS12_parse() and PKCS12_create(). Update PKCS12_parse() so it copies the friendlyName and the keyid to the certificates aux info. [Steve Henson] *) Fix bug in PKCS7_verify() which caused an infinite loop if there was more than one signature. [Sven Uszpelkat ] *) Major change in util/mkdef.pl to include extra information about each symbol, as well as presentig variables as well as functions. This change means that there's n more need to rebuild the .num files when some algorithms are excluded. [Richard Levitte] *) Allow the verify time to be set by an application, rather than always using the current time. [Steve Henson] *) Phase 2 verify code reorganisation. The certificate verify code now looks up an issuer certificate by a number of criteria: subject name, authority key id and key usage. It also verifies self signed certificates by the same criteria. The main comparison function is X509_check_issued() which performs these checks. Lot of changes were necessary in order to support this without completely rewriting the lookup code. Authority and subject key identifier are now cached. The LHASH 'certs' is X509_STORE has now been replaced by a STACK_OF(X509_OBJECT). This is mainly because an LHASH can't store or retrieve multiple objects with the same hash value. As a result various functions (which were all internal use only) have changed to handle the new X509_STORE structure. This will break anything that messed round with X509_STORE internally. The functions X509_STORE_add_cert() now checks for an exact match, rather than just subject name. The X509_STORE API doesn't directly support the retrieval of multiple certificates matching a given criteria, however this can be worked round by performing a lookup first (which will fill the cache with candidate certificates) and then examining the cache for matches. This is probably the best we can do without throwing out X509_LOOKUP entirely (maybe later...). The X509_VERIFY_CTX structure has been enhanced considerably. All certificate lookup operations now go via a get_issuer() callback. Although this currently uses an X509_STORE it can be replaced by custom lookups. This is a simple way to bypass the X509_STORE hackery necessary to make this work and makes it possible to use more efficient techniques in future. A very simple version which uses a simple STACK for its trusted certificate store is also provided using X509_STORE_CTX_trusted_stack(). The verify_cb() and verify() callbacks now have equivalents in the X509_STORE_CTX structure. X509_STORE_CTX also has a 'flags' field which can be used to customise the verify behaviour. [Steve Henson] *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which excludes S/MIME capabilities. [Steve Henson] *) When a certificate request is read in keep a copy of the original encoding of the signed data and use it when outputing again. Signatures then use the original encoding rather than a decoded, encoded version which may cause problems if the request is improperly encoded. [Steve Henson] *) For consistency with other BIO_puts implementations, call buffer_write(b, ...) directly in buffer_puts instead of calling BIO_write(b, ...). In BIO_puts, increment b->num_write as in BIO_write. [Peter.Sylvester@EdelWeb.fr] *) Fix BN_mul_word for the case where the word is 0. (We have to use BN_zero, we may not return a BIGNUM with an array consisting of words set to zero.) [Bodo Moeller] *) Avoid calling abort() from within the library when problems are detected, except if preprocessor symbols have been defined (such as REF_CHECK, BN_DEBUG etc.). [Bodo Moeller] *) New openssl application 'rsautl'. This utility can be used for low level RSA operations. DER public key BIO/fp routines also added. [Steve Henson] *) New Configure entry and patches for compiling on QNX 4. [Andreas Schneider ] *) A demo state-machine implementation was sponsored by Nuron (http://www.nuron.com/) and is now available in demos/state_machine. [Ben Laurie] *) New options added to the 'dgst' utility for signature generation and verification. [Steve Henson] *) Unrecognized PKCS#7 content types are now handled via a catch all ASN1_TYPE structure. This allows unsupported types to be stored as a "blob" and an application can encode and decode it manually. [Steve Henson] *) Fix various signed/unsigned issues to make a_strex.c compile under VC++. [Oscar Jacobsson ] *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct length if passed a buffer. ASN1_INTEGER_to_BN failed if passed a NULL BN and its argument was negative. [Steve Henson, pointed out by Sven Heiberg ] *) Modification to PKCS#7 encoding routines to output definite length encoding. Since currently the whole structures are in memory there's not real point in using indefinite length constructed encoding. However if OpenSSL is compiled with the flag PKCS7_INDEFINITE_ENCODING the old form is used. [Steve Henson] *) Added BIO_vprintf() and BIO_vsnprintf(). [Richard Levitte] *) Added more prefixes to parse for in the the strings written through a logging bio, to cover all the levels that are available through syslog. The prefixes are now: PANIC, EMERG, EMR => LOG_EMERG ALERT, ALR => LOG_ALERT CRIT, CRI => LOG_CRIT ERROR, ERR => LOG_ERR WARNING, WARN, WAR => LOG_WARNING NOTICE, NOTE, NOT => LOG_NOTICE INFO, INF => LOG_INFO DEBUG, DBG => LOG_DEBUG and as before, if none of those prefixes are present at the beginning of the string, LOG_ERR is chosen. On Win32, the LOG_* levels are mapped according to this: LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE LOG_WARNING => EVENTLOG_WARNING_TYPE LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE [Richard Levitte] *) Made it possible to reconfigure with just the configuration argument "reconf" or "reconfigure". The command line arguments are stored in Makefile.ssl in the variable CONFIGURE_ARGS, and are retrieved from there when reconfiguring. [Richard Levitte] *) MD4 implemented. [Assar Westerlund , Richard Levitte] *) Add the arguments -CAfile and -CApath to the pkcs12 utility. [Richard Levitte] *) The obj_dat.pl script was messing up the sorting of object names. The reason was that it compared the quoted version of strings as a result "OCSP" > "OCSP Signing" because " > SPACE. Changed script to store unquoted versions of names and add quotes on output. It was also omitting some names from the lookup table if they were given a default value (that is if SN is missing it is given the same value as LN and vice versa), these are now added on the grounds that if an object has a name we should be able to look it up. Finally added warning output when duplicate short or long names are found. [Steve Henson] *) Changes needed for Tandem NSK. [Scott Uroff ] *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in RSA_padding_check_SSLv23(), special padding was never detected and thus the SSL 3.0/TLS 1.0 countermeasure against protocol version rollback attacks was not effective. In s23_clnt.c, don't use special rollback-attack detection padding (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the client; similarly, in s23_srvr.c, don't do the rollback check if SSL 2.0 is the only protocol enabled in the server. [Bodo Moeller] *) Make it possible to get hexdumps of unprintable data with 'openssl asn1parse'. By implication, the functions ASN1_parse_dump() and BIO_dump_indent() are added. [Richard Levitte] *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex() these print out strings and name structures based on various flags including RFC2253 support and proper handling of multibyte characters. Added options to the 'x509' utility to allow the various flags to be set. [Steve Henson] *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME. Also change the functions X509_cmp_current_time() and X509_gmtime_adj() work with an ASN1_TIME structure, this will enable certificates using GeneralizedTime in validity dates to be checked. [Steve Henson] *) Make the NEG_PUBKEY_BUG code (which tolerates invalid negative public key encodings) on by default, NO_NEG_PUBKEY_BUG can be set to disable it. [Steve Henson] *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT content octets. An i2c_ASN1_OBJECT is unnecessary because the encoding can be trivially obtained from the structure. [Steve Henson] *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock), not read locks (CRYPTO_r_[un]lock). [Bodo Moeller] *) A first attempt at creating official support for shared libraries through configuration. I've kept it so the default is static libraries only, and the OpenSSL programs are always statically linked for now, but there are preparations for dynamic linking in place. This has been tested on Linux and Tru64. [Richard Levitte] *) Randomness polling function for Win9x, as described in: Peter Gutmann, Software Generation of Practically Strong Random Numbers. [Ulf Möller] *) Fix so PRNG is seeded in req if using an already existing DSA key. [Steve Henson] *) New options to smime application. -inform and -outform allow alternative formats for the S/MIME message including PEM and DER. The -content option allows the content to be specified separately. This should allow things like Netscape form signing output easier to verify. [Steve Henson] *) Fix the ASN1 encoding of tags using the 'long form'. [Steve Henson] *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT STRING types. These convert content octets to and from the underlying type. The actual tag and length octets are already assumed to have been read in and checked. These are needed because all other string types have virtually identical handling apart from the tag. By having versions of the ASN1 functions that just operate on content octets IMPLICIT tagging can be handled properly. It also allows the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED and ASN1_INTEGER are identical apart from the tag. [Steve Henson] *) Change the handling of OID objects as follows: - New object identifiers are inserted in objects.txt, following the syntax given in objects.README. - objects.pl is used to process obj_mac.num and create a new obj_mac.h. - obj_dat.pl is used to create a new obj_dat.h, using the data in obj_mac.h. This is currently kind of a hack, and the perl code in objects.pl isn't very elegant, but it works as I intended. The simplest way to check that it worked correctly is to look in obj_dat.h and check the array nid_objs and make sure the objects haven't moved around (this is important!). Additions are OK, as well as consistent name changes. [Richard Levitte] *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1'). [Bodo Moeller] *) Addition of the command line parameter '-rand file' to 'openssl req'. The given file adds to whatever has already been seeded into the random pool through the RANDFILE configuration file option or environment variable, or the default random state file. [Richard Levitte] *) mkstack.pl now sorts each macro group into lexical order. Previously the output order depended on the order the files appeared in the directory, resulting in needless rewriting of safestack.h . [Steve Henson] *) Patches to make OpenSSL compile under Win32 again. Mostly work arounds for the VC++ problem that it treats func() as func(void). Also stripped out the parts of mkdef.pl that added extra typesafe functions: these no longer exist. [Steve Henson] *) Reorganisation of the stack code. The macros are now all collected in safestack.h . Each macro is defined in terms of a "stack macro" of the form SKM_(type, a, b). The DEBUG_SAFESTACK is now handled in terms of function casts, this has the advantage of retaining type safety without the use of additional functions. If DEBUG_SAFESTACK is not defined then the non typesafe macros are used instead. Also modified the mkstack.pl script to handle the new form. Needs testing to see if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK the default if no major problems. Similar behaviour for ASN1_SET_OF and PKCS12_STACK_OF. [Steve Henson] *) When some versions of IIS use the 'NET' form of private key the key derivation algorithm is different. Normally MD5(password) is used as a 128 bit RC4 key. In the modified case MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same as the old Netscape_RSA functions except they have an additional 'sgckey' parameter which uses the modified algorithm. Also added an -sgckey command line option to the rsa utility. Thanks to Adrian Peck for posting details of the modified algorithm to openssl-dev. [Steve Henson] *) The evp_local.h macros were using 'c.##kname' which resulted in invalid expansion on some systems (SCO 5.0.5 for example). Corrected to 'c.kname'. [Phillip Porch ] *) New X509_get1_email() and X509_REQ_get1_email() functions that return a STACK of email addresses from a certificate or request, these look in the subject name and the subject alternative name extensions and omit any duplicate addresses. [Steve Henson] *) Re-implement BN_mod_exp2_mont using independent (and larger) windows. This makes DSA verification about 2 % faster. [Bodo Moeller] *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5 (meaning that now 2^5 values will be precomputed, which is only 4 KB plus overhead for 1024 bit moduli). This makes exponentiations about 0.5 % faster for 1024 bit exponents (as measured by "openssl speed rsa2048"). [Bodo Moeller] *) Rename memory handling macros to avoid conflicts with other software: Malloc => OPENSSL_malloc Malloc_locked => OPENSSL_malloc_locked Realloc => OPENSSL_realloc Free => OPENSSL_free [Richard Levitte] *) New function BN_mod_exp_mont_word for small bases (roughly 15% faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange). [Bodo Moeller] *) CygWin32 support. [John Jarvie ] *) The type-safe stack code has been rejigged. It is now only compiled in when OpenSSL is configured with the DEBUG_SAFESTACK option and by default all type-specific stack functions are "#define"d back to standard stack functions. This results in more streamlined output but retains the type-safety checking possibilities of the original approach. [Geoff Thorpe] *) The STACK code has been cleaned up, and certain type declarations that didn't make a lot of sense have been brought in line. This has also involved a cleanup of sorts in safestack.h to more correctly map type-safe stack functions onto their plain stack counterparts. This work has also resulted in a variety of "const"ifications of lots of the code, especially "_cmp" operations which should normally be prototyped with "const" parameters anyway. [Geoff Thorpe] *) When generating bytes for the first time in md_rand.c, 'stir the pool' by seeding with STATE_SIZE dummy bytes (with zero entropy count). (The PRNG state consists of two parts, the large pool 'state' and 'md', where all of 'md' is used each time the PRNG is used, but 'state' is used only indexed by a cyclic counter. As entropy may not be well distributed from the beginning, 'md' is important as a chaining variable. However, the output function chains only half of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains all of 'md', and seeding with STATE_SIZE dummy bytes will result in all of 'state' being rewritten, with the new values depending on virtually all of 'md'. This overcomes the 80 bit limitation.) [Bodo Moeller] *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when the handshake is continued after ssl_verify_cert_chain(); otherwise, if SSL_VERIFY_NONE is set, remaining error codes can lead to 'unexplainable' connection aborts later. [Bodo Moeller; problem tracked down by Lutz Jaenicke] *) Major EVP API cipher revision. Add hooks for extra EVP features. This allows various cipher parameters to be set in the EVP interface. Support added for variable key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and setting of RC2 and RC5 parameters. Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length ciphers. Remove lots of duplicated code from the EVP library. For example *every* cipher init() function handles the 'iv' in the same way according to the cipher mode. They also all do nothing if the 'key' parameter is NULL and for CFB and OFB modes they zero ctx->num. New functionality allows removal of S/MIME code RC2 hack. Most of the routines have the same form and so can be declared in terms of macros. By shifting this to the top level EVP_CipherInit() it can be removed from all individual ciphers. If the cipher wants to handle IVs or keys differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT flags. Change lots of functions like EVP_EncryptUpdate() to now return a value: although software versions of the algorithms cannot fail any installed hardware versions can. [Steve Henson] *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if this option is set, tolerate broken clients that send the negotiated protocol version number instead of the requested protocol version number. [Bodo Moeller] *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag; i.e. non-zero for export ciphersuites, zero otherwise. Previous versions had this flag inverted, inconsistent with rsa_tmp_cb (..._TMP_RSA_CB). [Bodo Moeller; problem reported by Amit Chopra] *) Add missing DSA library text string. Work around for some IIS key files with invalid SEQUENCE encoding. [Steve Henson] *) Add a document (doc/standards.txt) that list all kinds of standards and so on that are implemented in OpenSSL. [Richard Levitte] *) Enhance c_rehash script. Old version would mishandle certificates with the same subject name hash and wouldn't handle CRLs at all. Added -fingerprint option to crl utility, to support new c_rehash features. [Steve Henson] *) Eliminate non-ANSI declarations in crypto.h and stack.h. [Ulf Möller] *) Fix for SSL server purpose checking. Server checking was rejecting certificates which had extended key usage present but no ssl client purpose. [Steve Henson, reported by Rene Grosser ] *) Make PKCS#12 code work with no password. The PKCS#12 spec is a little unclear about how a blank password is handled. Since the password in encoded as a BMPString with terminating double NULL a zero length password would end up as just the double NULL. However no password at all is different and is handled differently in the PKCS#12 key generation code. NS treats a blank password as zero length. MSIE treats it as no password on export: but it will try both on import. We now do the same: PKCS12_parse() tries zero length and no password if the password is set to "" or NULL (NULL is now a valid password: it wasn't before) as does the pkcs12 application. [Steve Henson] *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use perror when PEM_read_bio_X509_REQ fails, the error message must be obtained from the error queue. [Bodo Moeller] *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing it in ERR_remove_state if appropriate, and change ERR_get_state accordingly to avoid race conditions (this is necessary because thread_hash is no longer constant once set). [Bodo Moeller] *) Bugfix for linux-elf makefile.one. [Ulf Möller] *) RSA_get_default_method() will now cause a default RSA_METHOD to be chosen if one doesn't exist already. Previously this was only set during a call to RSA_new() or RSA_new_method(NULL) meaning it was possible for RSA_get_default_method() to return NULL. [Geoff Thorpe] *) Added native name translation to the existing DSO code that will convert (if the flag to do so is set) filenames that are sufficiently small and have no path information into a canonical native form. Eg. "blah" converted to "libblah.so" or "blah.dll" etc. [Geoff Thorpe] *) New function ERR_error_string_n(e, buf, len) which is like ERR_error_string(e, buf), but writes at most 'len' bytes including the 0 terminator. For ERR_error_string_n, 'buf' may not be NULL. [Damien Miller , Bodo Moeller] *) CONF library reworked to become more general. A new CONF configuration file reader "class" is implemented as well as a new functions (NCONF_*, for "New CONF") to handle it. The now old CONF_* functions are still there, but are reimplemented to work in terms of the new functions. Also, a set of functions to handle the internal storage of the configuration data is provided to make it easier to write new configuration file reader "classes" (I can definitely see something reading a configuration file in XML format, for example), called _CONF_*, or "the configuration storage API"... The new configuration file reading functions are: NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio, NCONF_get_section, NCONF_get_string, NCONF_get_numbre NCONF_default, NCONF_WIN32 NCONF_dump_fp, NCONF_dump_bio NCONF_default and NCONF_WIN32 are method (or "class") choosers, NCONF_new creates a new CONF object. This works in the same way as other interfaces in OpenSSL, like the BIO interface. NCONF_dump_* dump the internal storage of the configuration file, which is useful for debugging. All other functions take the same arguments as the old CONF_* functions wth the exception of the first that must be a `CONF *' instead of a `LHASH *'. To make it easer to use the new classes with the old CONF_* functions, the function CONF_set_default_method is provided. [Richard Levitte] *) Add '-tls1' option to 'openssl ciphers', which was already mentioned in the documentation but had not been implemented. (This option is not yet really useful because even the additional experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.) [Bodo Moeller] *) Initial DSO code added into libcrypto for letting OpenSSL (and OpenSSL-based applications) load shared libraries and bind to them in a portable way. [Geoff Thorpe, with contributions from Richard Levitte] Changes between 0.9.5 and 0.9.5a [1 Apr 2000] *) Make sure _lrotl and _lrotr are only used with MSVC. *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status (the default implementation of RAND_status). *) Rename openssl x509 option '-crlext', which was added in 0.9.5, to '-clrext' (= clear extensions), as intended and documented. [Bodo Moeller; inconsistency pointed out by Michael Attili ] *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length was larger than the MD block size. [Steve Henson, pointed out by Yost William ] *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set() using the passed key: if the passed key was a private key the result of X509_print(), for example, would be to print out all the private key components. [Steve Henson] *) des_quad_cksum() byte order bug fix. [Ulf Möller, using the problem description in krb4-0.9.7, where the solution is attributed to Derrick J Brashear ] *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly discouraged. [Steve Henson, pointed out by Brian Korver ] *) For easily testing in shell scripts whether some command 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX' returns with exit code 0 iff no command of the given name is available. 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases, the output goes to stdout and nothing is printed to stderr. Additional arguments are always ignored. Since for each cipher there is a command of the same name, the 'no-cipher' compilation switches can be tested this way. ('openssl no-XXX' is not able to detect pseudo-commands such as 'quit', 'list-XXX-commands', or 'no-XXX' itself.) [Bodo Moeller] *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration. [Bodo Moeller] *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE is set; it will be thrown away anyway because each handshake creates its own key. ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition to parameters -- in previous versions (since OpenSSL 0.9.3) the 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining you effectivly got SSL_OP_SINGLE_DH_USE when using this macro. [Bodo Moeller] *) New s_client option -ign_eof: EOF at stdin is ignored, and 'Q' and 'R' lose their special meanings (quit/renegotiate). This is part of what -quiet does; unlike -quiet, -ign_eof does not suppress any output. [Richard Levitte] *) Add compatibility options to the purpose and trust code. The purpose X509_PURPOSE_ANY is "any purpose" which automatically accepts a certificate or CA, this was the previous behaviour, with all the associated security issues. X509_TRUST_COMPAT is the old trust behaviour: only and automatically trust self signed roots in certificate store. A new trust setting X509_TRUST_DEFAULT is used to specify that a purpose has no associated trust setting and it should instead use the value in the default purpose. [Steve Henson] *) Fix the PKCS#8 DSA private key code so it decodes keys again and fix a memory leak. [Steve Henson] *) In util/mkerr.pl (which implements 'make errors'), preserve reason strings from the previous version of the .c file, as the default to have only downcase letters (and digits) in automatically generated reasons codes is not always appropriate. [Bodo Moeller] *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table using strerror. Previously, ERR_reason_error_string() returned library names as reason strings for SYSerr; but SYSerr is a special case where small numbers are errno values, not library numbers. [Bodo Moeller] *) Add '-dsaparam' option to 'openssl dhparam' application. This converts DSA parameters into DH parameters. (When creating parameters, DSA_generate_parameters is used.) [Bodo Moeller] *) Include 'length' (recommended exponent length) in C code generated by 'openssl dhparam -C'. [Bodo Moeller] *) The second argument to set_label in perlasm was already being used so couldn't be used as a "file scope" flag. Moved to third argument which was free. [Steve Henson] *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes instead of RAND_bytes for encryption IVs and salts. [Bodo Moeller] *) Include RAND_status() into RAND_METHOD instead of implementing it only for md_rand.c Otherwise replacing the PRNG by calling RAND_set_rand_method would be impossible. [Bodo Moeller] *) Don't let DSA_generate_key() enter an infinite loop if the random number generation fails. [Bodo Moeller] *) New 'rand' application for creating pseudo-random output. [Bodo Moeller] *) Added configuration support for Linux/IA64 [Rolf Haberrecker ] *) Assembler module support for Mingw32. [Ulf Möller] *) Shared library support for HPUX (in shlib/). [Lutz Jaenicke and Anonymous] *) Shared library support for Solaris gcc. [Lutz Behnke ] Changes between 0.9.4 and 0.9.5 [28 Feb 2000] *) PKCS7_encrypt() was adding text MIME headers twice because they were added manually and by SMIME_crlf_copy(). [Steve Henson] *) In bntest.c don't call BN_rand with zero bits argument. [Steve Henson, pointed out by Andrew W. Gray ] *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n] case was implemented. This caused BN_div_recp() to fail occasionally. [Ulf Möller] *) Add an optional second argument to the set_label() in the perl assembly language builder. If this argument exists and is set to 1 it signals that the assembler should use a symbol whose scope is the entire file, not just the current function. This is needed with MASM which uses the format label:: for this scope. [Steve Henson, pointed out by Peter Runestig ] *) Change the ASN1 types so they are typedefs by default. Before almost all types were #define'd to ASN1_STRING which was causing STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING) for example. [Steve Henson] *) Change names of new functions to the new get1/get0 naming convention: After 'get1', the caller owns a reference count and has to call ..._free; 'get0' returns a pointer to some data structure without incrementing reference counters. (Some of the existing 'get' functions increment a reference counter, some don't.) Similarly, 'set1' and 'add1' functions increase reference counters or duplicate objects. [Steve Henson] *) Allow for the possibility of temp RSA key generation failure: the code used to assume it always worked and crashed on failure. [Steve Henson] *) Fix potential buffer overrun problem in BIO_printf(). [Ulf Möller, using public domain code by Patrick Powell; problem pointed out by David Sacerdote ] *) Support EGD . New functions RAND_egd() and RAND_status(). In the command line application, the EGD socket can be specified like a seed file using RANDFILE or -rand. [Ulf Möller] *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures. Some CAs (e.g. Verisign) distribute certificates in this form. [Steve Henson] *) Remove the SSL_ALLOW_ADH compile option and set the default cipher list to exclude them. This means that no special compilation option is needed to use anonymous DH: it just needs to be included in the cipher list. [Steve Henson] *) Change the EVP_MD_CTX_type macro so its meaning consistent with EVP_MD_type. The old functionality is available in a new macro called EVP_MD_md(). Change code that uses it and update docs. [Steve Henson] *) ..._ctrl functions now have corresponding ..._callback_ctrl functions where the 'void *' argument is replaced by a function pointer argument. Previously 'void *' was abused to point to functions, which works on many platforms, but is not correct. As these functions are usually called by macros defined in OpenSSL header files, most source code should work without changes. [Richard Levitte] *) (which is created by Configure) now contains sections with information on -D... compiler switches used for compiling the library so that applications can see them. To enable one of these sections, a pre-processor symbol OPENSSL_..._DEFINES must be defined. E.g., #define OPENSSL_ALGORITHM_DEFINES #include defines all pertinent NO_ symbols, such as NO_IDEA, NO_RSA, etc. [Richard Levitte, Ulf and Bodo Möller] *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS record layer. [Bodo Moeller] *) Change the 'other' type in certificate aux info to a STACK_OF X509_ALGOR. Although not an AlgorithmIdentifier as such it has the required ASN1 format: arbitrary types determined by an OID. [Steve Henson] *) Add some PEM_write_X509_REQ_NEW() functions and a command line argument to 'req'. This is not because the function is newer or better than others it just uses the work 'NEW' in the certificate request header lines. Some software needs this. [Steve Henson] *) Reorganise password command line arguments: now passwords can be obtained from various sources. Delete the PEM_cb function and make it the default behaviour: i.e. if the callback is NULL and the usrdata argument is not NULL interpret it as a null terminated pass phrase. If usrdata and the callback are NULL then the pass phrase is prompted for as usual. [Steve Henson] *) Add support for the Compaq Atalla crypto accelerator. If it is installed, the support is automatically enabled. The resulting binaries will autodetect the card and use it if present. [Ben Laurie and Compaq Inc.] *) Work around for Netscape hang bug. This sends certificate request and server done in one record. Since this is perfectly legal in the SSL/TLS protocol it isn't a "bug" option and is on by default. See the bugs/SSLv3 entry for more info. [Steve Henson] *) HP-UX tune-up: new unified configs, HP C compiler bug workaround. [Andy Polyakov] *) Add -rand argument to smime and pkcs12 applications and read/write of seed file. [Steve Henson] *) New 'passwd' tool for crypt(3) and apr1 password hashes. [Bodo Moeller] *) Add command line password options to the remaining applications. [Steve Henson] *) Bug fix for BN_div_recp() for numerators with an even number of bits. [Ulf Möller] *) More tests in bntest.c, and changed test_bn output. [Ulf Möller] *) ./config recognizes MacOS X now. [Andy Polyakov] *) Bug fix for BN_div() when the first words of num and divsor are equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0). [Ulf Möller] *) Add support for various broken PKCS#8 formats, and command line options to produce them. [Steve Henson] *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to get temporary BIGNUMs from a BN_CTX. [Ulf Möller] *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont() for p == 0. [Ulf Möller] *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and include a #define from the old name to the new. The original intent was that statically linked binaries could for example just call SSLeay_add_all_ciphers() to just add ciphers to the table and not link with digests. This never worked becayse SSLeay_add_all_digests() and SSLeay_add_all_ciphers() were in the same source file so calling one would link with the other. They are now in separate source files. [Steve Henson] *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'. [Steve Henson] *) Use a less unusual form of the Miller-Rabin primality test (it used a binary algorithm for exponentiation integrated into the Miller-Rabin loop, our standard modexp algorithms are faster). [Bodo Moeller] *) Support for the EBCDIC character set completed. [Martin Kraemer ] *) Source code cleanups: use const where appropriate, eliminate casts, use void * instead of char * in lhash. [Ulf Möller] *) Bugfix: ssl3_send_server_key_exchange was not restartable (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of this the server could overwrite ephemeral keys that the client has already seen). [Bodo Moeller] *) Turn DSA_is_prime into a macro that calls BN_is_prime, using 50 iterations of the Rabin-Miller test. DSA_generate_parameters now uses BN_is_prime_fasttest (with 50 iterations of the Rabin-Miller test as required by the appendix to FIPS PUB 186[-1]) instead of DSA_is_prime. As BN_is_prime_fasttest includes trial division, DSA parameter generation becomes much faster. This implies a change for the callback functions in DSA_is_prime and DSA_generate_parameters: The callback function is called once for each positive witness in the Rabin-Miller test, not just occasionally in the inner loop; and the parameters to the callback function now provide an iteration count for the outer loop rather than for the current invocation of the inner loop. DSA_generate_parameters additionally can call the callback function with an 'iteration count' of -1, meaning that a candidate has passed the trial division test (when q is generated from an application-provided seed, trial division is skipped). [Bodo Moeller] *) New function BN_is_prime_fasttest that optionally does trial division before starting the Rabin-Miller test and has an additional BN_CTX * argument (whereas BN_is_prime always has to allocate at least one BN_CTX). 'callback(1, -1, cb_arg)' is called when a number has passed the trial division stage. [Bodo Moeller] *) Fix for bug in CRL encoding. The validity dates weren't being handled as ASN1_TIME. [Steve Henson] *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file. [Steve Henson] *) New function BN_pseudo_rand(). [Ulf Möller] *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable) bignum version of BN_from_montgomery() with the working code from SSLeay 0.9.0 (the word based version is faster anyway), and clean up the comments. [Ulf Möller] *) Avoid a race condition in s2_clnt.c (function get_server_hello) that made it impossible to use the same SSL_SESSION data structure in SSL2 clients in multiple threads. [Bodo Moeller] *) The return value of RAND_load_file() no longer counts bytes obtained by stat(). RAND_load_file(..., -1) is new and uses the complete file to seed the PRNG (previously an explicit byte count was required). [Ulf Möller, Bodo Möller] *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes used (char *) instead of (void *) and had casts all over the place. [Steve Henson] *) Make BN_generate_prime() return NULL on error if ret!=NULL. [Ulf Möller] *) Retain source code compatibility for BN_prime_checks macro: BN_is_prime(..., BN_prime_checks, ...) now uses BN_prime_checks_for_size to determine the appropriate number of Rabin-Miller iterations. [Ulf Möller] *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to DH_CHECK_P_NOT_SAFE_PRIME. (Check if this is true? OpenPGP calls them "strong".) [Ulf Möller] *) Merge the functionality of "dh" and "gendh" programs into a new program "dhparam". The old programs are retained for now but will handle DH keys (instead of parameters) in future. [Steve Henson] *) Make the ciphers, s_server and s_client programs check the return values when a new cipher list is set. [Steve Henson] *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit ciphers. Before when the 56bit ciphers were enabled the sorting was wrong. The syntax for the cipher sorting has been extended to support sorting by cipher-strength (using the strength_bits hard coded in the tables). The new command is "@STRENGTH" (see also doc/apps/ciphers.pod). Fix a bug in the cipher-command parser: when supplying a cipher command string with an "undefined" symbol (neither command nor alphanumeric [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now an error is flagged. Due to the strength-sorting extension, the code of the ssl_create_cipher_list() function was completely rearranged. I hope that the readability was also increased :-) [Lutz Jaenicke ] *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1 for the first serial number and places 2 in the serial number file. This avoids problems when the root CA is created with serial number zero and the first user certificate has the same issuer name and serial number as the root CA. [Steve Henson] *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses the new code. Add documentation for this stuff. [Steve Henson] *) Changes to X509_ATTRIBUTE utilities. These have been renamed from X509_*() to X509at_*() on the grounds that they don't handle X509 structures and behave in an analagous way to the X509v3 functions: they shouldn't be called directly but wrapper functions should be used instead. So we also now have some wrapper functions that call the X509at functions when passed certificate requests. (TO DO: similar things can be done with PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other things. Some of these need some d2i or i2d and print functionality because they handle more complex structures.) [Steve Henson] *) Add missing #ifndefs that caused missing symbols when building libssl as a shared library without RSA. Use #ifndef NO_SSL2 instead of NO_RSA in ssl/s2*.c. [Kris Kennaway , modified by Ulf Möller] *) Precautions against using the PRNG uninitialized: RAND_bytes() now has a return value which indicates the quality of the random data (1 = ok, 0 = not seeded). Also an error is recorded on the thread's error queue. New function RAND_pseudo_bytes() generates output that is guaranteed to be unique but not unpredictable. RAND_add is like RAND_seed, but takes an extra argument for an entropy estimate (RAND_seed always assumes full entropy). [Ulf Möller] *) Do more iterations of Rabin-Miller probable prime test (specifically, 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes instead of only 2 for all lengths; see BN_prime_checks_for_size definition in crypto/bn/bn_prime.c for the complete table). This guarantees a false-positive rate of at most 2^-80 for random input. [Bodo Moeller] *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs. [Bodo Moeller] *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain in the 0.9.5 release), this returns the chain from an X509_CTX structure with a dup of the stack and all the X509 reference counts upped: so the stack will exist after X509_CTX_cleanup() has been called. Modify pkcs12.c to use this. Also make SSL_SESSION_print() print out the verify return code. [Steve Henson] *) Add manpage for the pkcs12 command. Also change the default behaviour so MAC iteration counts are used unless the new -nomaciter option is used. This improves file security and only older versions of MSIE (4.0 for example) need it. [Steve Henson] *) Honor the no-xxx Configure options when creating .DEF files. [Ulf Möller] *) Add PKCS#10 attributes to field table: challengePassword, unstructuredName and unstructuredAddress. These are taken from draft PKCS#9 v2.0 but are compatible with v1.2 provided no international characters are used. More changes to X509_ATTRIBUTE code: allow the setting of types based on strings. Remove the 'loc' parameter when adding attributes because these will be a SET OF encoding which is sorted in ASN1 order. [Steve Henson] *) Initial changes to the 'req' utility to allow request generation automation. This will allow an application to just generate a template file containing all the field values and have req construct the request. Initial support for X509_ATTRIBUTE handling. Stacks of these are used all over the place including certificate requests and PKCS#7 structures. They are currently handled manually where necessary with some primitive wrappers for PKCS#7. The new functions behave in a manner analogous to the X509 extension functions: they allow attributes to be looked up by NID and added. Later something similar to the X509V3 code would be desirable to automatically handle the encoding, decoding and printing of the more complex types. The string types like challengePassword can be handled by the string table functions. Also modified the multi byte string table handling. Now there is a 'global mask' which masks out certain types. The table itself can use the flag STABLE_NO_MASK to ignore the mask setting: this is useful when for example there is only one permissible type (as in countryName) and using the mask might result in no valid types at all. [Steve Henson] *) Clean up 'Finished' handling, and add functions SSL_get_finished and SSL_get_peer_finished to allow applications to obtain the latest Finished messages sent to the peer or expected from the peer, respectively. (SSL_get_peer_finished is usually the Finished message actually received from the peer, otherwise the protocol will be aborted.) As the Finished message are message digests of the complete handshake (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can be used for external authentication procedures when the authentication provided by SSL/TLS is not desired or is not enough. [Bodo Moeller] *) Enhanced support for Alpha Linux is added. Now ./config checks if the host supports BWX extension and if Compaq C is present on the $PATH. Just exploiting of the BWX extension results in 20-30% performance kick for some algorithms, e.g. DES and RC4 to mention a couple. Compaq C in turn generates ~20% faster code for MD5 and SHA1. [Andy Polyakov] *) Add support for MS "fast SGC". This is arguably a violation of the SSL3/TLS protocol. Netscape SGC does two handshakes: the first with weak crypto and after checking the certificate is SGC a second one with strong crypto. MS SGC stops the first handshake after receiving the server certificate message and sends a second client hello. Since a server will typically do all the time consuming operations before expecting any further messages from the client (server key exchange is the most expensive) there is little difference between the two. To get OpenSSL to support MS SGC we have to permit a second client hello message after we have sent server done. In addition we have to reset the MAC if we do get this second client hello. [Steve Henson] *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide if a DER encoded private key is RSA or DSA traditional format. Changed d2i_PrivateKey_bio() to use it. This is only needed for the "traditional" format DER encoded private key. Newer code should use PKCS#8 format which has the key type encoded in the ASN1 structure. Added DER private key support to pkcs8 application. [Steve Henson] *) SSL 3/TLS 1 servers now don't request certificates when an anonymous ciphersuites has been selected (as required by the SSL 3/TLS 1 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT is set, we interpret this as a request to violate the specification (the worst that can happen is a handshake failure, and 'correct' behaviour would result in a handshake failure anyway). [Bodo Moeller] *) In SSL_CTX_add_session, take into account that there might be multiple SSL_SESSION structures with the same session ID (e.g. when two threads concurrently obtain them from an external cache). The internal cache can handle only one SSL_SESSION with a given ID, so if there's a conflict, we now throw out the old one to achieve consistency. [Bodo Moeller] *) Add OIDs for idea and blowfish in CBC mode. This will allow both to be used in PKCS#5 v2.0 and S/MIME. Also add checking to some routines that use cipher OIDs: some ciphers do not have OIDs defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for example. [Steve Henson] *) Simplify the trust setting structure and code. Now we just have two sequences of OIDs for trusted and rejected settings. These will typically have values the same as the extended key usage extension and any application specific purposes. The trust checking code now has a default behaviour: it will just check for an object with the same NID as the passed id. Functions can be provided to override either the default behaviour or the behaviour for a given id. SSL client, server and email already have functions in place for compatibility: they check the NID and also return "trusted" if the certificate is self signed. [Steve Henson] *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the traditional format into an EVP_PKEY structure. [Steve Henson] *) Add a password callback function PEM_cb() which either prompts for a password if usr_data is NULL or otherwise assumes it is a null terminated password. Allow passwords to be passed on command line environment or config files in a few more utilities. [Steve Henson] *) Add a bunch of DER and PEM functions to handle PKCS#8 format private keys. Add some short names for PKCS#8 PBE algorithms and allow them to be specified on the command line for the pkcs8 and pkcs12 utilities. Update documentation. [Steve Henson] *) Support for ASN1 "NULL" type. This could be handled before by using ASN1_TYPE but there wasn't any function that would try to read a NULL and produce an error if it couldn't. For compatibility we also have ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and don't allocate anything because they don't need to. [Steve Henson] *) Initial support for MacOS is now provided. Examine INSTALL.MacOS for details. [Andy Polyakov, Roy Woods ] *) Rebuild of the memory allocation routines used by OpenSSL code and possibly others as well. The purpose is to make an interface that provide hooks so anyone can build a separate set of allocation and deallocation routines to be used by OpenSSL, for example memory pool implementations, or something else, which was previously hard since Malloc(), Realloc() and Free() were defined as macros having the values malloc, realloc and free, respectively (except for Win32 compilations). The same is provided for memory debugging code. OpenSSL already comes with functionality to find memory leaks, but this gives people a chance to debug other memory problems. With these changes, a new set of functions and macros have appeared: CRYPTO_set_mem_debug_functions() [F] CRYPTO_get_mem_debug_functions() [F] CRYPTO_dbg_set_options() [F] CRYPTO_dbg_get_options() [F] CRYPTO_malloc_debug_init() [M] The memory debug functions are NULL by default, unless the library is compiled with CRYPTO_MDEBUG or friends is defined. If someone wants to debug memory anyway, CRYPTO_malloc_debug_init() (which gives the standard debugging functions that come with OpenSSL) or CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions provided by the library user) must be used. When the standard debugging functions are used, CRYPTO_dbg_set_options can be used to request additional information: CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting the CRYPTO_MDEBUG_xxx macro when compiling the library. Also, things like CRYPTO_set_mem_functions will always give the expected result (the new set of functions is used for allocation and deallocation) at all times, regardless of platform and compiler options. To finish it up, some functions that were never use in any other way than through macros have a new API and new semantic: CRYPTO_dbg_malloc() CRYPTO_dbg_realloc() CRYPTO_dbg_free() All macros of value have retained their old syntax. [Richard Levitte and Bodo Moeller] *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the ordering of SMIMECapabilities wasn't in "strength order" and there was a missing NULL in the AlgorithmIdentifier for the SHA1 signature algorithm. [Steve Henson] *) Some ASN1 types with illegal zero length encoding (INTEGER, ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines. [Frans Heymans , modified by Steve Henson] *) Merge in my S/MIME library for OpenSSL. This provides a simple S/MIME API on top of the PKCS#7 code, a MIME parser (with enough functionality to handle multipart/signed properly) and a utility called 'smime' to call all this stuff. This is based on code I originally wrote for Celo who have kindly allowed it to be included in OpenSSL. [Steve Henson] *) Add variants des_set_key_checked and des_set_key_unchecked of des_set_key (aka des_key_sched). Global variable des_check_key decides which of these is called by des_set_key; this way des_check_key behaves as it always did, but applications and the library itself, which was buggy for des_check_key == 1, have a cleaner way to pick the version they need. [Bodo Moeller] *) New function PKCS12_newpass() which changes the password of a PKCS12 structure. [Steve Henson] *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and dynamic mix. In both cases the ids can be used as an index into the table. Also modified the X509_TRUST_add() and X509_PURPOSE_add() functions so they accept a list of the field values and the application doesn't need to directly manipulate the X509_TRUST structure. [Steve Henson] *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't need initialising. [Steve Henson] *) Modify the way the V3 extension code looks up extensions. This now works in a similar way to the object code: we have some "standard" extensions in a static table which is searched with OBJ_bsearch() and the application can add dynamic ones if needed. The file crypto/x509v3/ext_dat.h now has the info: this file needs to be updated whenever a new extension is added to the core code and kept in ext_nid order. There is a simple program 'tabtest.c' which checks this. New extensions are not added too often so this file can readily be maintained manually. There are two big advantages in doing things this way. The extensions can be looked up immediately and no longer need to be "added" using X509V3_add_standard_extensions(): this function now does nothing. [Side note: I get *lots* of email saying the extension code doesn't work because people forget to call this function] Also no dynamic allocation is done unless new extensions are added: so if we don't add custom extensions there is no need to call X509V3_EXT_cleanup(). [Steve Henson] *) Modify enc utility's salting as follows: make salting the default. Add a magic header, so unsalted files fail gracefully instead of just decrypting to garbage. This is because not salting is a big security hole, so people should be discouraged from doing it. [Ben Laurie] *) Fixes and enhancements to the 'x509' utility. It allowed a message digest to be passed on the command line but it only used this parameter when signing a certificate. Modified so all relevant operations are affected by the digest parameter including the -fingerprint and -x509toreq options. Also -x509toreq choked if a DSA key was used because it didn't fix the digest. [Steve Henson] *) Initial certificate chain verify code. Currently tests the untrusted certificates for consistency with the verify purpose (which is set when the X509_STORE_CTX structure is set up) and checks the pathlength. There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour: this is because it will reject chains with invalid extensions whereas every previous version of OpenSSL and SSLeay made no checks at all. Trust code: checks the root CA for the relevant trust settings. Trust settings have an initial value consistent with the verify purpose: e.g. if the verify purpose is for SSL client use it expects the CA to be trusted for SSL client use. However the default value can be changed to permit custom trust settings: one example of this would be to only trust certificates from a specific "secure" set of CAs. Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions which should be used for version portability: especially since the verify structure is likely to change more often now. SSL integration. Add purpose and trust to SSL_CTX and SSL and functions to set them. If not set then assume SSL clients will verify SSL servers and vice versa. Two new options to the verify program: -untrusted allows a set of untrusted certificates to be passed in and -purpose which sets the intended purpose of the certificate. If a purpose is set then the new chain verify code is used to check extension consistency. [Steve Henson] *) Support for the authority information access extension. [Steve Henson] *) Modify RSA and DSA PEM read routines to transparently handle PKCS#8 format private keys. New *_PUBKEY_* functions that handle public keys in a format compatible with certificate SubjectPublicKeyInfo structures. Unfortunately there were already functions called *_PublicKey_* which used various odd formats so these are retained for compatibility: however the DSA variants were never in a public release so they have been deleted. Changed dsa/rsa utilities to handle the new format: note no releases ever handled public keys so we should be OK. The primary motivation for this change is to avoid the same fiasco that dogs private keys: there are several incompatible private key formats some of which are standard and some OpenSSL specific and require various evil hacks to allow partial transparent handling and even then it doesn't work with DER formats. Given the option anything other than PKCS#8 should be dumped: but the other formats have to stay in the name of compatibility. With public keys and the benefit of hindsight one standard format is used which works with EVP_PKEY, RSA or DSA structures: though it clearly returns an error if you try to read the wrong kind of key. Added a -pubkey option to the 'x509' utility to output the public key. Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*()) that do the same as the EVP_PKEY_assign_*() except they up the reference count of the added key (they don't "swallow" the supplied key). [Steve Henson] *) Fixes to crypto/x509/by_file.c the code to read in certificates and CRLs would fail if the file contained no certificates or no CRLs: added a new function to read in both types and return the number read: this means that if none are read it will be an error. The DER versions of the certificate and CRL reader would always fail because it isn't possible to mix certificates and CRLs in DER format without choking one or the other routine. Changed this to just read a certificate: this is the best we can do. Also modified the code in apps/verify.c to take notice of return codes: it was previously attempting to read in certificates from NULL pointers and ignoring any errors: this is one reason why the cert and CRL reader seemed to work. It doesn't check return codes from the default certificate routines: these may well fail if the certificates aren't installed. [Steve Henson] *) Code to support otherName option in GeneralName. [Steve Henson] *) First update to verify code. Change the verify utility so it warns if it is passed a self signed certificate: for consistency with the normal behaviour. X509_verify has been modified to it will now verify a self signed certificate if *exactly* the same certificate appears in the store: it was previously impossible to trust a single self signed certificate. This means that: openssl verify ss.pem now gives a warning about a self signed certificate but openssl verify -CAfile ss.pem ss.pem is OK. [Steve Henson] *) For servers, store verify_result in SSL_SESSION data structure (and add it to external session representation). This is needed when client certificate verifications fails, but an application-provided verification callback (set by SSL_CTX_set_cert_verify_callback) allows accepting the session anyway (i.e. leaves x509_store_ctx->error != X509_V_OK but returns 1): When the session is reused, we have to set ssl->verify_result to the appropriate error code to avoid security holes. [Bodo Moeller, problem pointed out by Lutz Jaenicke] *) Fix a bug in the new PKCS#7 code: it didn't consider the case in PKCS7_dataInit() where the signed PKCS7 structure didn't contain any existing data because it was being created. [Po-Cheng Chen , slightly modified by Steve Henson] *) Add a salt to the key derivation routines in enc.c. This forms the first 8 bytes of the encrypted file. Also add a -S option to allow a salt to be input on the command line. [Steve Henson] *) New function X509_cmp(). Oddly enough there wasn't a function to compare two certificates. We do this by working out the SHA1 hash and comparing that. X509_cmp() will be needed by the trust code. [Steve Henson] *) SSL_get1_session() is like SSL_get_session(), but increments the reference count in the SSL_SESSION returned. [Geoff Thorpe ] *) Fix for 'req': it was adding a null to request attributes. Also change the X509_LOOKUP and X509_INFO code to handle certificate auxiliary information. [Steve Henson] *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document the 'enc' command. [Steve Henson] *) Add the possibility to add extra information to the memory leak detecting output, to form tracebacks, showing from where each allocation was originated: CRYPTO_push_info("constant string") adds the string plus current file name and line number to a per-thread stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info() is like calling CYRPTO_pop_info() until the stack is empty. Also updated memory leak detection code to be multi-thread-safe. [Richard Levitte] *) Add options -text and -noout to pkcs7 utility and delete the encryption options which never did anything. Update docs. [Steve Henson] *) Add options to some of the utilities to allow the pass phrase to be included on either the command line (not recommended on OSes like Unix) or read from the environment. Update the manpages and fix a few bugs. [Steve Henson] *) Add a few manpages for some of the openssl commands. [Steve Henson] *) Fix the -revoke option in ca. It was freeing up memory twice, leaking and not finding already revoked certificates. [Steve Henson] *) Extensive changes to support certificate auxiliary information. This involves the use of X509_CERT_AUX structure and X509_AUX functions. An X509_AUX function such as PEM_read_X509_AUX() can still read in a certificate file in the usual way but it will also read in any additional "auxiliary information". By doing things this way a fair degree of compatibility can be retained: existing certificates can have this information added using the new 'x509' options. Current auxiliary information includes an "alias" and some trust settings. The trust settings will ultimately be used in enhanced certificate chain verification routines: currently a certificate can only be trusted if it is self signed and then it is trusted for all purposes. [Steve Henson] *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The problem was that one of the replacement routines had not been working since SSLeay releases. For now the offending routine has been replaced with non-optimised assembler. Even so, this now gives around 95% performance improvement for 1024 bit RSA signs. [Mark Cox] *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 handling. Most clients have the effective key size in bits equal to the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key. A few however don't do this and instead use the size of the decrypted key to determine the RC2 key length and the AlgorithmIdentifier to determine the effective key length. In this case the effective key length can still be 40 bits but the key length can be 168 bits for example. This is fixed by manually forcing an RC2 key into the EVP_PKEY structure because the EVP code can't currently handle unusual RC2 key sizes: it always assumes the key length and effective key length are equal. [Steve Henson] *) Add a bunch of functions that should simplify the creation of X509_NAME structures. Now you should be able to do: X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0); and have it automatically work out the correct field type and fill in the structures. The more adventurous can try: X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0); and it will (hopefully) work out the correct multibyte encoding. [Steve Henson] *) Change the 'req' utility to use the new field handling and multibyte copy routines. Before the DN field creation was handled in an ad hoc way in req, ca, and x509 which was rather broken and didn't support BMPStrings or UTF8Strings. Since some software doesn't implement BMPStrings or UTF8Strings yet, they can be enabled using the config file using the dirstring_type option. See the new comment in the default openssl.cnf for more info. [Steve Henson] *) Make crypto/rand/md_rand.c more robust: - Assure unique random numbers after fork(). - Make sure that concurrent threads access the global counter and md serializably so that we never lose entropy in them or use exactly the same state in multiple threads. Access to the large state is not always serializable because the additional locking could be a performance killer, and md should be large enough anyway. [Bodo Moeller] *) New file apps/app_rand.c with commonly needed functionality for handling the random seed file. Use the random seed file in some applications that previously did not: ca, dsaparam -genkey (which also ignored its '-rand' option), s_client, s_server, x509 (when signing). Except on systems with /dev/urandom, it is crucial to have a random seed file at least for key creation, DSA signing, and for DH exchanges; for RSA signatures we could do without one. gendh and gendsa (unlike genrsa) used to read only the first byte of each file listed in the '-rand' option. The function as previously found in genrsa is now in app_rand.c and is used by all programs that support '-rand'. [Bodo Moeller] *) In RAND_write_file, use mode 0600 for creating files; don't just chmod when it may be too late. [Bodo Moeller] *) Report an error from X509_STORE_load_locations when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed. [Bill Perry] *) New function ASN1_mbstring_copy() this copies a string in either ASCII, Unicode, Universal (4 bytes per character) or UTF8 format into an ASN1_STRING type. A mask of permissible types is passed and it chooses the "minimal" type to use or an error if not type is suitable. [Steve Henson] *) Add function equivalents to the various macros in asn1.h. The old macros are retained with an M_ prefix. Code inside the library can use the M_ macros. External code (including the openssl utility) should *NOT* in order to be "shared library friendly". [Steve Henson] *) Add various functions that can check a certificate's extensions to see if it usable for various purposes such as SSL client, server or S/MIME and CAs of these types. This is currently VERY EXPERIMENTAL but will ultimately be used for certificate chain verification. Also added a -purpose flag to x509 utility to print out all the purposes. [Steve Henson] *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated functions. [Steve Henson] *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search for, obtain and decode and extension and obtain its critical flag. This allows all the necessary extension code to be handled in a single function call. [Steve Henson] *) RC4 tune-up featuring 30-40% performance improvement on most RISC platforms. See crypto/rc4/rc4_enc.c for further details. [Andy Polyakov] *) New -noout option to asn1parse. This causes no output to be produced its main use is when combined with -strparse and -out to extract data from a file (which may not be in ASN.1 format). [Steve Henson] *) Fix for pkcs12 program. It was hashing an invalid certificate pointer when producing the local key id. [Richard Levitte ] *) New option -dhparam in s_server. This allows a DH parameter file to be stated explicitly. If it is not stated then it tries the first server certificate file. The previous behaviour hard coded the filename "server.pem". [Steve Henson] *) Add -pubin and -pubout options to the rsa and dsa commands. These allow a public key to be input or output. For example: openssl rsa -in key.pem -pubout -out pubkey.pem Also added necessary DSA public key functions to handle this. [Steve Henson] *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained in the message. This was handled by allowing X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. [Steve Henson, reported by Sampo Kellomaki ] *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null to the end of the strings whereas this didn't. This would cause problems if strings read with d2i_ASN1_bytes() were later modified. [Steve Henson, reported by Arne Ansper ] *) Fix for base64 decode bug. When a base64 bio reads only one line of data and it contains EOF it will end up returning an error. This is caused by input 46 bytes long. The cause is due to the way base64 BIOs find the start of base64 encoded data. They do this by trying a trial decode on each line until they find one that works. When they do a flag is set and it starts again knowing it can pass all the data directly through the decoder. Unfortunately it doesn't reset the context it uses. This means that if EOF is reached an attempt is made to pass two EOFs through the context and this causes the resulting error. This can also cause other problems as well. As is usual with these problems it takes *ages* to find and the fix is trivial: move one line. [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] *) Ugly workaround to get s_client and s_server working under Windows. The old code wouldn't work because it needed to select() on sockets and the tty (for keypresses and to see if data could be written). Win32 only supports select() on sockets so we select() with a 1s timeout on the sockets and then see if any characters are waiting to be read, if none are present then we retry, we also assume we can always write data to the tty. This isn't nice because the code then blocks until we've received a complete line of data and it is effectively polling the keyboard at 1s intervals: however it's quite a bit better than not working at all :-) A dedicated Windows application might handle this with an event loop for example. [Steve Henson] *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions will be called when RSA_sign() and RSA_verify() are used. This is useful if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. For this to work properly RSA_public_decrypt() and RSA_private_encrypt() should *not* be used: RSA_sign() and RSA_verify() must be used instead. This necessitated the support of an extra signature type NID_md5_sha1 for SSL signatures and modifications to the SSL library to use it instead of calling RSA_public_decrypt() and RSA_private_encrypt(). [Steve Henson] *) Add new -verify -CAfile and -CApath options to the crl program, these will lookup a CRL issuers certificate and verify the signature in a similar way to the verify program. Tidy up the crl program so it no longer accesses structures directly. Make the ASN1 CRL parsing a bit less strict. It will now permit CRL extensions even if it is not a V2 CRL: this will allow it to tolerate some broken CRLs. [Steve Henson] *) Initialize all non-automatic variables each time one of the openssl sub-programs is started (this is necessary as they may be started multiple times from the "OpenSSL>" prompt). [Lennart Bang, Bodo Moeller] *) Preliminary compilation option RSA_NULL which disables RSA crypto without removing all other RSA functionality (this is what NO_RSA does). This is so (for example) those in the US can disable those operations covered by the RSA patent while allowing storage and parsing of RSA keys and RSA key generation. [Steve Henson] *) Non-copying interface to BIO pairs. (still largely untested) [Bodo Moeller] *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive ASCII string. This was handled independently in various places before. [Steve Henson] *) New functions UTF8_getc() and UTF8_putc() that parse and generate UTF8 strings a character at a time. [Steve Henson] *) Use client_version from client hello to select the protocol (s23_srvr.c) and for RSA client key exchange verification (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. [Bodo Moeller] *) Add various utility functions to handle SPKACs, these were previously handled by poking round in the structure internals. Added new function NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to print, verify and generate SPKACs. Based on an original idea from Massimiliano Pala but extensively modified. [Steve Henson] *) RIPEMD160 is operational on all platforms and is back in 'make test'. [Andy Polyakov] *) Allow the config file extension section to be overwritten on the command line. Based on an original idea from Massimiliano Pala . The new option is called -extensions and can be applied to ca, req and x509. Also -reqexts to override the request extensions in req and -crlexts to override the crl extensions in ca. [Steve Henson] *) Add new feature to the SPKAC handling in ca. Now you can include the same field multiple times by preceding it by "XXXX." for example: 1.OU="Unit name 1" 2.OU="Unit name 2" this is the same syntax as used in the req config file. [Steve Henson] *) Allow certificate extensions to be added to certificate requests. These are specified in a 'req_extensions' option of the req section of the config file. They can be printed out with the -text option to req but are otherwise ignored at present. [Steve Henson] *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first data read consists of only the final block it would not decrypted because EVP_CipherUpdate() would correctly report zero bytes had been decrypted. A misplaced 'break' also meant the decrypted final block might not be copied until the next read. [Steve Henson] *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added a few extra parameters to the DH structure: these will be useful if for example we want the value of 'q' or implement X9.42 DH. [Steve Henson] *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and provides hooks that allow the default DSA functions or functions on a "per key" basis to be replaced. This allows hardware acceleration and hardware key storage to be handled without major modification to the library. Also added low level modexp hooks and CRYPTO_EX structure and associated functions. [Steve Henson] *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO as "read only": it can't be written to and the buffer it points to will not be freed. Reading from a read only BIO is much more efficient than a normal memory BIO. This was added because there are several times when an area of memory needs to be read from a BIO. The previous method was to create a memory BIO and write the data to it, this results in two copies of the data and an O(n^2) reading algorithm. There is a new function BIO_new_mem_buf() which creates a read only memory BIO from an area of memory. Also modified the PKCS#7 routines to use read only memory BIOs. [Steve Henson] *) Bugfix: ssl23_get_client_hello did not work properly when called in state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read, but a retry condition occured while trying to read the rest. [Bodo Moeller] *) The PKCS7_ENC_CONTENT_new() function was setting the content type as NID_pkcs7_encrypted by default: this was wrong since this should almost always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle the encrypted data type: this is a more sensible place to put it and it allows the PKCS#12 code to be tidied up that duplicated this functionality. [Steve Henson] *) Changed obj_dat.pl script so it takes its input and output files on the command line. This should avoid shell escape redirection problems under Win32. [Steve Henson] *) Initial support for certificate extension requests, these are included in things like Xenroll certificate requests. Included functions to allow extensions to be obtained and added. [Steve Henson] *) -crlf option to s_client and s_server for sending newlines as CRLF (as required by many protocols). [Bodo Moeller] Changes between 0.9.3a and 0.9.4 [09 Aug 1999] *) Install libRSAglue.a when OpenSSL is built with RSAref. [Ralf S. Engelschall] *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. [Andrija Antonijevic ] *) Fix -startdate and -enddate (which was missing) arguments to 'ca' program. [Steve Henson] *) New function DSA_dup_DH, which duplicates DSA parameters/keys as DH parameters/keys (q is lost during that conversion, but the resulting DH parameters contain its length). For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is much faster than DH_generate_parameters (which creates parameters where p = 2*q + 1), and also the smaller q makes DH computations much more efficient (160-bit exponentiation instead of 1024-bit exponentiation); so this provides a convenient way to support DHE ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of utter importance to use SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); or SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); when such DH parameters are used, because otherwise small subgroup attacks may become possible! [Bodo Moeller] *) Avoid memory leak in i2d_DHparams. [Bodo Moeller] *) Allow the -k option to be used more than once in the enc program: this allows the same encrypted message to be read by multiple recipients. [Steve Henson] *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts an ASN1_OBJECT to a text string. If the "no_name" parameter is set then it will always use the numerical form of the OID, even if it has a short or long name. [Steve Henson] *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp method only got called if p,q,dmp1,dmq1,iqmp components were present, otherwise bn_mod_exp was called. In the case of hardware keys for example no private key components need be present and it might store extra data in the RSA structure, which cannot be accessed from bn_mod_exp. By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for private key operations. [Steve Henson] *) Added support for SPARC Linux. [Andy Polyakov] *) pem_password_cb function type incompatibly changed from typedef int pem_password_cb(char *buf, int size, int rwflag); to ....(char *buf, int size, int rwflag, void *userdata); so that applications can pass data to their callbacks: The PEM[_ASN1]_{read,write}... functions and macros now take an additional void * argument, which is just handed through whenever the password callback is called. [Damien Miller ; tiny changes by Bodo Moeller] New function SSL_CTX_set_default_passwd_cb_userdata. Compatibility note: As many C implementations push function arguments onto the stack in reverse order, the new library version is likely to interoperate with programs that have been compiled with the old pem_password_cb definition (PEM_whatever takes some data that happens to be on the stack as its last argument, and the callback just ignores this garbage); but there is no guarantee whatsoever that this will work. *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused problems not only on Windows, but also on some Unix platforms. To avoid problematic command lines, these definitions are now in an auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). [Bodo Moeller] *) MIPS III/IV assembler module is reimplemented. [Andy Polyakov] *) More DES library cleanups: remove references to srand/rand and delete an unused file. [Ulf Möller] *) Add support for the the free Netwide assembler (NASM) under Win32, since not many people have MASM (ml) and it can be hard to obtain. This is currently experimental but it seems to work OK and pass all the tests. Check out INSTALL.W32 for info. [Steve Henson] *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections without temporary keys kept an extra copy of the server key, and connections with temporary keys did not free everything in case of an error. [Bodo Moeller] *) New function RSA_check_key and new openssl rsa option -check for verifying the consistency of RSA keys. [Ulf Moeller, Bodo Moeller] *) Various changes to make Win32 compile work: 1. Casts to avoid "loss of data" warnings in p5_crpt2.c 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned comparison" warnings. 3. Add sk__sort to DEF file generator and do make update. [Steve Henson] *) Add a debugging option to PKCS#5 v2 key generation function: when you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and derived keys are printed to stderr. [Steve Henson] *) Copy the flags in ASN1_STRING_dup(). [Roman E. Pavlov ] *) The x509 application mishandled signing requests containing DSA keys when the signing key was also DSA and the parameters didn't match. It was supposed to omit the parameters when they matched the signing key: the verifying software was then supposed to automatically use the CA's parameters if they were absent from the end user certificate. Omitting parameters is no longer recommended. The test was also the wrong way round! This was probably due to unusual behaviour in EVP_cmp_parameters() which returns 1 if the parameters match. This meant that parameters were omitted when they *didn't* match and the certificate was useless. Certificates signed with 'ca' didn't have this bug. [Steve Henson, reported by Doug Erickson ] *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems. The interface is as follows: Applications can use CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); "off" is now the default. The library internally uses CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() to disable memory-checking temporarily. Some inconsistent states that previously were possible (and were even the default) are now avoided. -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time with each memory chunk allocated; this is occasionally more helpful than just having a counter. -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID. -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future extensions. [Bodo Moeller] *) Introduce "mode" for SSL structures (with defaults in SSL_CTX), which largely parallels "options", but is for changing API behaviour, whereas "options" are about protocol behaviour. Initial "mode" flags are: SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when a single record has been written. SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write retries use the same buffer location. (But all of the contents must be copied!) [Bodo Moeller] *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options worked. *) Fix problems with no-hmac etc. [Ulf Möller, pointed out by Brian Wellington ] *) New functions RSA_get_default_method(), RSA_set_method() and RSA_get_method(). These allows replacement of RSA_METHODs without having to mess around with the internals of an RSA structure. [Steve Henson] *) Fix memory leaks in DSA_do_sign and DSA_is_prime. Also really enable memory leak checks in openssl.c and in some test programs. [Chad C. Mulligan, Bodo Moeller] *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess up the length of negative integers. This has now been simplified to just store the length when it is first determined and use it later, rather than trying to keep track of where data is copied and updating it to point to the end. [Steve Henson, reported by Brien Wheeler ] *) Add a new function PKCS7_signatureVerify. This allows the verification of a PKCS#7 signature but with the signing certificate passed to the function itself. This contrasts with PKCS7_dataVerify which assumes the certificate is present in the PKCS#7 structure. This isn't always the case: certificates can be omitted from a PKCS#7 structure and be distributed by "out of band" means (such as a certificate database). [Steve Henson] *) Complete the PEM_* macros with DECLARE_PEM versions to replace the function prototypes in pem.h, also change util/mkdef.pl to add the necessary function names. [Steve Henson] *) mk1mf.pl (used by Windows builds) did not properly read the options set by Configure in the top level Makefile, and Configure was not even able to write more than one option correctly. Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended. [Bodo Moeller] *) New functions CONF_load_bio() and CONF_load_fp() to allow a config file to be loaded from a BIO or FILE pointer. The BIO version will for example allow memory BIOs to contain config info. [Steve Henson] *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS. Whoever hopes to achieve shared-library compatibility across versions must use this, not the compile-time macro. (Exercise 0.9.4: Which is the minimum library version required by such programs?) Note: All this applies only to multi-threaded programs, others don't need locks. [Bodo Moeller] *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests through a BIO pair triggered the default case, i.e. SSLerr(...,SSL_R_UNKNOWN_STATE). [Bodo Moeller] *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications can use the SSL library even if none of the specific BIOs is appropriate. [Bodo Moeller] *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value for the encoded length. [Jeon KyoungHo ] *) Add initial documentation of the X509V3 functions. [Steve Henson] *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and PEM_write_bio_PKCS8PrivateKey() that are equivalent to PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more secure PKCS#8 private key format with a high iteration count. [Steve Henson] *) Fix determination of Perl interpreter: A perl or perl5 _directory_ in $PATH was also accepted as the interpreter. [Ralf S. Engelschall] *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking wrong with it but it was very old and did things like calling PEM_ASN1_read() directly and used MD5 for the hash not to mention some unusual formatting. [Steve Henson] *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed to use the new extension code. [Steve Henson] *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c with macros. This should make it easier to change their form, add extra arguments etc. Fix a few PEM prototypes which didn't have cipher as a constant. [Steve Henson] *) Add to configuration table a new entry that can specify an alternative name for unistd.h (for pre-POSIX systems); we need this for NeXTstep, according to Mark Crispin . [Bodo Moeller] #if 0 *) DES CBC did not update the IV. Weird. [Ben Laurie] #else des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does. Changing the behaviour of the former might break existing programs -- where IV updating is needed, des_ncbc_encrypt can be used. #endif *) When bntest is run from "make test" it drives bc to check its calculations, as well as internally checking them. If an internal check fails, it needs to cause bc to give a non-zero result or make test carries on without noticing the failure. Fixed. [Ben Laurie] *) DES library cleanups. [Ulf Möller] *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit ciphers. NOTE: although the key derivation function has been verified against some published test vectors it has not been extensively tested yet. Added a -v2 "cipher" option to pkcs8 application to allow the use of v2.0. [Steve Henson] *) Instead of "mkdir -p", which is not fully portable, use new Perl script "util/mkdir-p.pl". [Bodo Moeller] *) Rewrite the way password based encryption (PBE) is handled. It used to assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms but doesn't apply to PKCS#5 v2.0 where it can be something else. Now the 'parameter' field of the AlgorithmIdentifier is passed to the underlying key generation function so it must do its own ASN1 parsing. This has also changed the EVP_PBE_CipherInit() function which now has a 'parameter' argument instead of literal salt and iteration count values and the function EVP_PBE_ALGOR_CipherInit() has been deleted. [Steve Henson] *) Support for PKCS#5 v1.5 compatible password based encryption algorithms and PKCS#8 functionality. New 'pkcs8' application linked to openssl. Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE KEY" because this clashed with PKCS#8 unencrypted string. Since this value was just used as a "magic string" and not used directly its value doesn't matter. [Steve Henson] *) Introduce some semblance of const correctness to BN. Shame C doesn't support mutable. [Ben Laurie] *) "linux-sparc64" configuration (ultrapenguin). [Ray Miller ] "linux-sparc" configuration. [Christian Forster ] *) config now generates no-xxx options for missing ciphers. [Ulf Möller] *) Support the EBCDIC character set (work in progress). File ebcdic.c not yet included because it has a different license. [Martin Kraemer ] *) Support BS2000/OSD-POSIX. [Martin Kraemer ] *) Make callbacks for key generation use void * instead of char *. [Ben Laurie] *) Make S/MIME samples compile (not yet tested). [Ben Laurie] *) Additional typesafe stacks. [Ben Laurie] *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x). [Bodo Moeller] Changes between 0.9.3 and 0.9.3a [29 May 1999] *) New configuration variant "sco5-gcc". *) Updated some demos. [Sean O Riordain, Wade Scholine] *) Add missing BIO_free at exit of pkcs12 application. [Wu Zhigang] *) Fix memory leak in conf.c. [Steve Henson] *) Updates for Win32 to assembler version of MD5. [Steve Henson] *) Set #! path to perl in apps/der_chop to where we found it instead of using a fixed path. [Bodo Moeller] *) SHA library changes for irix64-mips4-cc. [Andy Polyakov] *) Improvements for VMS support. [Richard Levitte] Changes between 0.9.2b and 0.9.3 [24 May 1999] *) Bignum library bug fix. IRIX 6 passes "make test" now! This also avoids the problems with SC4.2 and unpatched SC5. [Andy Polyakov ] *) New functions sk_num, sk_value and sk_set to replace the previous macros. These are required because of the typesafe stack would otherwise break existing code. If old code used a structure member which used to be STACK and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with sk_num or sk_value it would produce an error because the num, data members are not present in STACK_OF. Now it just produces a warning. sk_set replaces the old method of assigning a value to sk_value (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code that does this will no longer work (and should use sk_set instead) but this could be regarded as a "questionable" behaviour anyway. [Steve Henson] *) Fix most of the other PKCS#7 bugs. The "experimental" code can now correctly handle encrypted S/MIME data. [Steve Henson] *) Change type of various DES function arguments from des_cblock (which means, in function argument declarations, pointer to char) to des_cblock * (meaning pointer to array with 8 char elements), which allows the compiler to do more typechecking; it was like that back in SSLeay, but with lots of ugly casts. Introduce new type const_des_cblock. [Bodo Moeller] *) Reorganise the PKCS#7 library and get rid of some of the more obvious problems: find RecipientInfo structure that matches recipient certificate and initialise the ASN1 structures properly based on passed cipher. [Steve Henson] *) Belatedly make the BN tests actually check the results. [Ben Laurie] *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion to and from BNs: it was completely broken. New compilation option NEG_PUBKEY_BUG to allow for some broken certificates that encode public key elements as negative integers. [Steve Henson] *) Reorganize and speed up MD5. [Andy Polyakov ] *) VMS support. [Richard Levitte ] *) New option -out to asn1parse to allow the parsed structure to be output to a file. This is most useful when combined with the -strparse option to examine the output of things like OCTET STRINGS. [Steve Henson] *) Make SSL library a little more fool-proof by not requiring any longer that SSL_set_{accept,connect}_state be called before SSL_{accept,connect} may be used (SSL_set_..._state is omitted in many applications because usually everything *appeared* to work as intended anyway -- now it really works as intended). [Bodo Moeller] *) Move openssl.cnf out of lib/. [Ulf Möller] *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+ [Ralf S. Engelschall] *) Various fixes to the EVP and PKCS#7 code. It may now be able to handle PKCS#7 enveloped data properly. [Sebastian Akerman , modified by Steve] *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of copying pointers. The cert_st handling is changed by this in various ways (and thus what used to be known as ctx->default_cert is now called ctx->cert, since we don't resort to s->ctx->[default_]cert any longer when s->cert does not give us what we need). ssl_cert_instantiate becomes obsolete by this change. As soon as we've got the new code right (possibly it already is?), we have solved a couple of bugs of the earlier code where s->cert was used as if it could not have been shared with other SSL structures. Note that using the SSL API in certain dirty ways now will result in different behaviour than observed with earlier library versions: Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx) does not influence s as it used to. In order to clean up things more thoroughly, inside SSL_SESSION we don't use CERT any longer, but a new structure SESS_CERT that holds per-session data (if available); currently, this is the peer's certificate chain and, for clients, the server's certificate and temporary key. CERT holds only those values that can have meaningful defaults in an SSL_CTX. [Bodo Moeller] *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure from the internal representation. Various PKCS#7 fixes: remove some evil casts and set the enc_dig_alg field properly based on the signing key type. [Steve Henson] *) Allow PKCS#12 password to be set from the command line or the environment. Let 'ca' get its config file name from the environment variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req' and 'x509'). [Steve Henson] *) Allow certificate policies extension to use an IA5STRING for the organization field. This is contrary to the PKIX definition but VeriSign uses it and IE5 only recognises this form. Document 'x509' extension option. [Steve Henson] *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic, without disallowing inline assembler and the like for non-pedantic builds. [Ben Laurie] *) Support Borland C++ builder. [Janez Jere , modified by Ulf Möller] *) Support Mingw32. [Ulf Möller] *) SHA-1 cleanups and performance enhancements. [Andy Polyakov ] *) Sparc v8plus assembler for the bignum library. [Andy Polyakov ] *) Accept any -xxx and +xxx compiler options in Configure. [Ulf Möller] *) Update HPUX configuration. [Anonymous] *) Add missing sk__unshift() function to safestack.h [Ralf S. Engelschall] *) New function SSL_CTX_use_certificate_chain_file that sets the "extra_cert"s in addition to the certificate. (This makes sense only for "PEM" format files, as chains as a whole are not DER-encoded.) [Bodo Moeller] *) Support verify_depth from the SSL API. x509_vfy.c had what can be considered an off-by-one-error: Its depth (which was not part of the external interface) was actually counting the number of certificates in a chain; now it really counts the depth. [Bodo Moeller] *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used instead of X509err, which often resulted in confusing error messages since the error codes are not globally unique (e.g. an alleged error in ssl3_accept when a certificate didn't match the private key). *) New function SSL_CTX_set_session_id_context that allows to set a default value (so that you don't need SSL_set_session_id_context for each connection using the SSL_CTX). [Bodo Moeller] *) OAEP decoding bug fix. [Ulf Möller] *) Support INSTALL_PREFIX for package builders, as proposed by David Harris. [Bodo Moeller] *) New Configure options "threads" and "no-threads". For systems where the proper compiler options are known (currently Solaris and Linux), "threads" is the default. [Bodo Moeller] *) New script util/mklink.pl as a faster substitute for util/mklink.sh. [Bodo Moeller] *) Install various scripts to $(OPENSSLDIR)/misc, not to $(INSTALLTOP)/bin -- they shouldn't clutter directories such as /usr/local/bin. [Bodo Moeller] *) "make linux-shared" to build shared libraries. [Niels Poppe ] *) New Configure option no- (rsa, idea, rc5, ...). [Ulf Möller] *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for extension adding in x509 utility. [Steve Henson] *) Remove NOPROTO sections and error code comments. [Ulf Möller] *) Partial rewrite of the DEF file generator to now parse the ANSI prototypes. [Steve Henson] *) New Configure options --prefix=DIR and --openssldir=DIR. [Ulf Möller] *) Complete rewrite of the error code script(s). It is all now handled by one script at the top level which handles error code gathering, header rewriting and C source file generation. It should be much better than the old method: it now uses a modified version of Ulf's parser to read the ANSI prototypes in all header files (thus the old K&R definitions aren't needed for error creation any more) and do a better job of translating function codes into names. The old 'ASN1 error code imbedded in a comment' is no longer necessary and it doesn't use .err files which have now been deleted. Also the error code call doesn't have to appear all on one line (which resulted in some large lines...). [Steve Henson] *) Change #include filenames from to . [Bodo Moeller] *) Change behaviour of ssl2_read when facing length-0 packets: Don't return 0 (which usually indicates a closed connection), but continue reading. [Bodo Moeller] *) Fix some race conditions. [Bodo Moeller] *) Add support for CRL distribution points extension. Add Certificate Policies and CRL distribution points documentation. [Steve Henson] *) Move the autogenerated header file parts to crypto/opensslconf.h. [Ulf Möller] *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of 8 of keying material. Merlin has also confirmed interop with this fix between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0. [Merlin Hughes ] *) Fix lots of warnings. [Richard Levitte ] *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if the directory spec didn't end with a LIST_SEPARATOR_CHAR. [Richard Levitte ] *) Fix problems with sizeof(long) == 8. [Andy Polyakov ] *) Change functions to ANSI C. [Ulf Möller] *) Fix typos in error codes. [Martin Kraemer , Ulf Möller] *) Remove defunct assembler files from Configure. [Ulf Möller] *) SPARC v8 assembler BIGNUM implementation. [Andy Polyakov ] *) Support for Certificate Policies extension: both print and set. Various additions to support the r2i method this uses. [Steve Henson] *) A lot of constification, and fix a bug in X509_NAME_oneline() that could return a const string when you are expecting an allocated buffer. [Ben Laurie] *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE types DirectoryString and DisplayText. [Steve Henson] *) Add code to allow r2i extensions to access the configuration database, add an LHASH database driver and add several ctx helper functions. [Steve Henson] *) Fix an evil bug in bn_expand2() which caused various BN functions to fail when they extended the size of a BIGNUM. [Steve Henson] *) Various utility functions to handle SXNet extension. Modify mkdef.pl to support typesafe stack. [Steve Henson] *) Fix typo in SSL_[gs]et_options(). [Nils Frostberg ] *) Delete various functions and files that belonged to the (now obsolete) old X509V3 handling code. [Steve Henson] *) New Configure option "rsaref". [Ulf Möller] *) Don't auto-generate pem.h. [Bodo Moeller] *) Introduce type-safe ASN.1 SETs. [Ben Laurie] *) Convert various additional casted stacks to type-safe STACK_OF() variants. [Ben Laurie, Ralf S. Engelschall, Steve Henson] *) Introduce type-safe STACKs. This will almost certainly break lots of code that links with OpenSSL (well at least cause lots of warnings), but fear not: the conversion is trivial, and it eliminates loads of evil casts. A few STACKed things have been converted already. Feel free to convert more. In the fullness of time, I'll do away with the STACK type altogether. [Ben Laurie] *) Add `openssl ca -revoke ' facility which revokes a certificate specified in by updating the entry in the index.txt file. This way one no longer has to edit the index.txt file manually for revoking a certificate. The -revoke option does the gory details now. [Massimiliano Pala , Ralf S. Engelschall] *) Fix `openssl crl -noout -text' combination where `-noout' killed the `-text' option at all and this way the `-noout -text' combination was inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'. [Ralf S. Engelschall] *) Make sure a corresponding plain text error message exists for the X509_V_ERR_CERT_REVOKED/23 error number which can occur when a verify callback function determined that a certificate was revoked. [Ralf S. Engelschall] *) Bugfix: In test/testenc, don't test "openssl " for ciphers that were excluded, e.g. by -DNO_IDEA. Also, test all available cipers including rc5, which was forgotten until now. In order to let the testing shell script know which algorithms are available, a new (up to now undocumented) command "openssl list-cipher-commands" is used. [Bodo Moeller] *) Bugfix: s_client occasionally would sleep in select() when it should have checked SSL_pending() first. [Bodo Moeller] *) New functions DSA_do_sign and DSA_do_verify to provide access to the raw DSA values prior to ASN.1 encoding. [Ulf Möller] *) Tweaks to Configure [Niels Poppe ] *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support, yet... [Steve Henson] *) New variables $(RANLIB) and $(PERL) in the Makefiles. [Ulf Möller] *) New config option to avoid instructions that are illegal on the 80386. The default code is faster, but requires at least a 486. [Ulf Möller] *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and SSL2_SERVER_VERSION (not used at all) macros, which are now the same as SSL2_VERSION anyway. [Bodo Moeller] *) New "-showcerts" option for s_client. [Bodo Moeller] *) Still more PKCS#12 integration. Add pkcs12 application to openssl application. Various cleanups and fixes. [Steve Henson] *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and modify error routines to work internally. Add error codes and PBE init to library startup routines. [Steve Henson] *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and packing functions to asn1 and evp. Changed function names and error codes along the way. [Steve Henson] *) PKCS12 integration: and so it begins... First of several patches to slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12 objects to objects.h [Steve Henson] *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1 and display support for Thawte strong extranet extension. [Steve Henson] *) Add LinuxPPC support. [Jeff Dubrule ] *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to bn_div_words in alpha.s. [Hannes Reinecke and Ben Laurie] *) Make sure the RSA OAEP test is skipped under -DRSAref because OAEP isn't supported when OpenSSL is built with RSAref. [Ulf Moeller ] *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h so they no longer are missing under -DNOPROTO. [Soren S. Jorvang ] Changes between 0.9.1c and 0.9.2b [22 Mar 1999] *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still doesn't work when the session is reused. Coming soon! [Ben Laurie] *) Fix a security hole, that allows sessions to be reused in the wrong context thus bypassing client cert protection! All software that uses client certs and session caches in multiple contexts NEEDS PATCHING to allow session reuse! A fuller solution is in the works. [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)] *) Some more source tree cleanups (removed obsolete files crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed permission on "config" script to be executable) and a fix for the INSTALL document. [Ulf Moeller ] *) Remove some legacy and erroneous uses of malloc, free instead of Malloc, Free. [Lennart Bang , with minor changes by Steve] *) Make rsa_oaep_test return non-zero on error. [Ulf Moeller ] *) Add support for native Solaris shared libraries. Configure solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice if someone would make that last step automatic. [Matthias Loepfe ] *) ctx_size was not built with the right compiler during "make links". Fixed. [Ben Laurie] *) Change the meaning of 'ALL' in the cipher list. It now means "everything except NULL ciphers". This means the default cipher list will no longer enable NULL ciphers. They need to be specifically enabled e.g. with the string "DEFAULT:eNULL". [Steve Henson] *) Fix to RSA private encryption routines: if p < q then it would occasionally produce an invalid result. This will only happen with externally generated keys because OpenSSL (and SSLeay) ensure p > q. [Steve Henson] *) Be less restrictive and allow also `perl util/perlpath.pl /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin', because this way one can also use an interpreter named `perl5' (which is usually the name of Perl 5.xxx on platforms where an Perl 4.x is still installed as `perl'). [Matthias Loepfe ] *) Let util/clean-depend.pl work also with older Perl 5.00x versions. [Matthias Loepfe ] *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add advapi32.lib to Win32 build and change the pem test comparision to fc.exe (thanks to Ulrich Kroener for the suggestion). Fix misplaced ASNI prototypes and declarations in evp.h and crypto/des/ede_cbcm_enc.c. [Steve Henson] *) DES quad checksum was broken on big-endian architectures. Fixed. [Ben Laurie] *) Comment out two functions in bio.h that aren't implemented. Fix up the Win32 test batch file so it (might) work again. The Win32 test batch file is horrible: I feel ill.... [Steve Henson] *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected in e_os.h. Audit of header files to check ANSI and non ANSI sections: 10 functions were absent from non ANSI section and not exported from Windows DLLs. Fixed up libeay.num for new functions. [Steve Henson] *) Make `openssl version' output lines consistent. [Ralf S. Engelschall] *) Fix Win32 symbol export lists for BIO functions: Added BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data to ms/libeay{16,32}.def. [Ralf S. Engelschall] *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled fine under Unix and passes some trivial tests I've now added. But the whole stuff is horribly incomplete, so a README.1ST with a disclaimer was added to make sure no one expects that this stuff really works in the OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and openssl_bio.xs. [Ralf S. Engelschall] *) Fix the generation of two part addresses in perl. [Kenji Miyake , integrated by Ben Laurie] *) Add config entry for Linux on MIPS. [John Tobey ] *) Make links whenever Configure is run, unless we are on Windoze. [Ben Laurie] *) Permit extensions to be added to CRLs using crl_section in openssl.cnf. Currently only issuerAltName and AuthorityKeyIdentifier make any sense in CRLs. [Steve Henson] *) Add a useful kludge to allow package maintainers to specify compiler and other platforms details on the command line without having to patch the Configure script everytime: One now can use ``perl Configure :
'', i.e. platform ids are allowed to have details appended to them (seperated by colons). This is treated as there would be a static pre-configured entry in Configure's %table under key with value
and ``perl Configure '' is called. So, when you want to perform a quick test-compile under FreeBSD 3.1 with pgcc and without assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"'' now, which overrides the FreeBSD-elf entry on-the-fly. [Ralf S. Engelschall] *) Disable new TLS1 ciphersuites by default: they aren't official yet. [Ben Laurie] *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified on the `perl Configure ...' command line. This way one can compile OpenSSL libraries with Position Independent Code (PIC) which is needed for linking it into DSOs. [Ralf S. Engelschall] *) Remarkably, export ciphers were totally broken and no-one had noticed! Fixed. [Ben Laurie] *) Cleaned up the LICENSE document: The official contact for any license questions now is the OpenSSL core team under openssl-core@openssl.org. And add a paragraph about the dual-license situation to make sure people recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply to the OpenSSL toolkit. [Ralf S. Engelschall] *) General source tree makefile cleanups: Made `making xxx in yyy...' display consistent in the source tree and replaced `/bin/rm' by `rm'. Additonally cleaned up the `make links' target: Remove unnecessary semicolons, subsequent redundant removes, inline point.sh into mklink.sh to speed processing and no longer clutter the display with confusing stuff. Instead only the actually done links are displayed. [Ralf S. Engelschall] *) Permit null encryption ciphersuites, used for authentication only. It used to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this. It is now necessary to set SSL_FORBID_ENULL to prevent the use of null encryption. [Ben Laurie] *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder signed attributes when verifying signatures (this would break them), the detached data encoding was wrong and public keys obtained using X509_get_pubkey() weren't freed. [Steve Henson] *) Add text documentation for the BUFFER functions. Also added a work around to a Win95 console bug. This was triggered by the password read stuff: the last character typed gets carried over to the next fread(). If you were generating a new cert request using 'req' for example then the last character of the passphrase would be CR which would then enter the first field as blank. [Steve Henson] *) Added the new `Includes OpenSSL Cryptography Software' button as doc/openssl_button.{gif,html} which is similar in style to the old SSLeay button and can be used by applications based on OpenSSL to show the relationship to the OpenSSL project. [Ralf S. Engelschall] *) Remove confusing variables in function signatures in files ssl/ssl_lib.c and ssl/ssl.h. [Lennart Bong ] *) Don't install bss_file.c under PREFIX/include/ [Lennart Bong ] *) Get the Win32 compile working again. Modify mkdef.pl so it can handle functions that return function pointers and has support for NT specific stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various #ifdef WIN32 and WINNTs sprinkled about the place and some changes from unsigned to signed types: this was killing the Win32 compile. [Steve Henson] *) Add new certificate file to stack functions, SSL_add_dir_cert_subjects_to_stack() and SSL_add_file_cert_subjects_to_stack(). These largely supplant SSL_load_client_CA_file(), and can be used to add multiple certs easily to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()). This means that Apache-SSL and similar packages don't have to mess around to add as many CAs as they want to the preferred list. [Ben Laurie] *) Experiment with doxygen documentation. Currently only partially applied to ssl/ssl_lib.c. See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with openssl.doxy as the configuration file. [Ben Laurie] *) Get rid of remaining C++-style comments which strict C compilers hate. [Ralf S. Engelschall, pointed out by Carlos Amengual] *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not compiled in by default: it has problems with large keys. [Steve Henson] *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and DH private keys and/or callback functions which directly correspond to their SSL_CTX_xxx() counterparts but work on a per-connection basis. This is needed for applications which have to configure certificates on a per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis (e.g. s_server). For the RSA certificate situation is makes no difference, but for the DSA certificate situation this fixes the "no shared cipher" problem where the OpenSSL cipher selection procedure failed because the temporary keys were not overtaken from the context and the API provided no way to reconfigure them. The new functions now let applications reconfigure the stuff and they are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new non-public-API function ssl_cert_instantiate() is used as a helper function and also to reduce code redundancy inside ssl_rsa.c. [Ralf S. Engelschall] *) Move s_server -dcert and -dkey options out of the undocumented feature area because they are useful for the DSA situation and should be recognized by the users. [Ralf S. Engelschall] *) Fix the cipher decision scheme for export ciphers: the export bits are *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within SSL_EXP_MASK. So, the original variable has to be used instead of the already masked variable. [Richard Levitte ] *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c [Richard Levitte ] *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() from `int' to `unsigned int' because it's a length and initialized by EVP_DigestFinal() which expects an `unsigned int *'. [Richard Levitte ] *) Don't hard-code path to Perl interpreter on shebang line of Configure script. Instead use the usual Shell->Perl transition trick. [Ralf S. Engelschall] *) Make `openssl x509 -noout -modulus' functional also for DSA certificates (in addition to RSA certificates) to match the behaviour of `openssl dsa -noout -modulus' as it's already the case for `openssl rsa -noout -modulus'. For RSA the -modulus is the real "modulus" while for DSA currently the public key is printed (a decision which was already done by `openssl dsa -modulus' in the past) which serves a similar purpose. Additionally the NO_RSA no longer completely removes the whole -modulus option; it now only avoids using the RSA stuff. Same applies to NO_DSA now, too. [Ralf S. Engelschall] *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested BIO. See the source (crypto/evp/bio_ok.c) for more info. [Arne Ansper ] *) Dump the old yucky req code that tried (and failed) to allow raw OIDs to be added. Now both 'req' and 'ca' can use new objects defined in the config file. [Steve Henson] *) Add cool BIO that does syslog (or event log on NT). [Arne Ansper , integrated by Ben Laurie] *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt. [Ben Laurie] *) Add preliminary config info for new extension code. [Steve Henson] *) Make RSA_NO_PADDING really use no padding. [Ulf Moeller ] *) Generate errors when private/public key check is done. [Ben Laurie] *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support for some CRL extensions and new objects added. [Steve Henson] *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private key usage extension and fuller support for authority key id. [Steve Henson] *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved padding method for RSA, which is recommended for new applications in PKCS #1 v2.0 (RFC 2437, October 1998). OAEP (Optimal Asymmetric Encryption Padding) has better theoretical foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure against Bleichbacher's attack on RSA. [Ulf Moeller , reformatted, corrected and integrated by Ben Laurie] *) Updates to the new SSL compression code [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] *) Fix so that the version number in the master secret, when passed via RSA, checks that if TLS was proposed, but we roll back to SSLv3 (because the server will not accept higher), that the version number is 0x03,0x01, not 0x03,0x00 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c [Steve Henson] *) Support for RAW extensions where an arbitrary extension can be created by including its DER encoding. See apps/openssl.cnf for an example. [Steve Henson] *) Make sure latest Perl versions don't interpret some generated C array code as Perl array code in the crypto/err/err_genc.pl script. [Lars Weber <3weber@informatik.uni-hamburg.de>] *) Modify ms/do_ms.bat to not generate assembly language makefiles since not many people have the assembler. Various Win32 compilation fixes and update to the INSTALL.W32 file with (hopefully) more accurate Win32 build instructions. [Steve Henson] *) Modify configure script 'Configure' to automatically create crypto/date.h file under Win32 and also build pem.h from pem.org. New script util/mkfiles.pl to create the MINFO file on environments that can't do a 'make files': perl util/mkfiles.pl >MINFO should work. [Steve Henson] *) Major rework of DES function declarations, in the pursuit of correctness and purity. As a result, many evil casts evaporated, and some weirdness, too. You may find this causes warnings in your code. Zapping your evil casts will probably fix them. Mostly. [Ben Laurie] *) Fix for a typo in asn1.h. Bug fix to object creation script obj_dat.pl. It considered a zero in an object definition to mean "end of object": none of the objects in objects.h have any zeros so it wasn't spotted. [Steve Henson, reported by Erwann ABALEA ] *) Add support for Triple DES Cipher Block Chaining with Output Feedback Masking (CBCM). In the absence of test vectors, the best I have been able to do is check that the decrypt undoes the encrypt, so far. Send me test vectors if you have them. [Ben Laurie] *) Correct calculation of key length for export ciphers (too much space was allocated for null ciphers). This has not been tested! [Ben Laurie] *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage message is now correct (it understands "crypto" and "ssl" on its command line). There is also now an "update" option. This will update the util/ssleay.num and util/libeay.num files with any new functions. If you do a: perl util/mkdef.pl crypto ssl update it will update them. [Steve Henson] *) Overhauled the Perl interface (perl/*): - ported BN stuff to OpenSSL's different BN library - made the perl/ source tree CVS-aware - renamed the package from SSLeay to OpenSSL (the files still contain their history because I've copied them in the repository) - removed obsolete files (the test scripts will be replaced by better Test::Harness variants in the future) [Ralf S. Engelschall] *) First cut for a very conservative source tree cleanup: 1. merge various obsolete readme texts into doc/ssleay.txt where we collect the old documents and readme texts. 2. remove the first part of files where I'm already sure that we no longer need them because of three reasons: either they are just temporary files which were left by Eric or they are preserved original files where I've verified that the diff is also available in the CVS via "cvs diff -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for the crypto/md/ stuff). [Ralf S. Engelschall] *) More extension code. Incomplete support for subject and issuer alt name, issuer and authority key id. Change the i2v function parameters and add an extra 'crl' parameter in the X509V3_CTX structure: guess what that's for :-) Fix to ASN1 macro which messed up IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED. [Steve Henson] *) Preliminary support for ENUMERATED type. This is largely copied from the INTEGER code. [Steve Henson] *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy. [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] *) Make sure `make rehash' target really finds the `openssl' program. [Ralf S. Engelschall, Matthias Loepfe ] *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd like to hear about it if this slows down other processors. [Ben Laurie] *) Add CygWin32 platform information to Configure script. [Alan Batie ] *) Fixed ms/32all.bat script: `no_asm' -> `no-asm' [Rainer W. Gerling ] *) New program nseq to manipulate netscape certificate sequences [Steve Henson] *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a few typos. [Steve Henson] *) Fixes to BN code. Previously the default was to define BN_RECURSION but the BN code had some problems that would cause failures when doing certificate verification and some other functions. [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] *) Add ASN1 and PEM code to support netscape certificate sequences. [Steve Henson] *) Add ASN1 and PEM code to support netscape certificate sequences. [Steve Henson] *) Add several PKIX and private extended key usage OIDs. [Steve Henson] *) Modify the 'ca' program to handle the new extension code. Modify openssl.cnf for new extension format, add comments. [Steve Henson] *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' and add a sample to openssl.cnf so req -x509 now adds appropriate CA extensions. [Steve Henson] *) Continued X509 V3 changes. Add to other makefiles, integrate with the error code, add initial support to X509_print() and x509 application. [Steve Henson] *) Takes a deep breath and start addding X509 V3 extension support code. Add files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this stuff is currently isolated and isn't even compiled yet. [Steve Henson] *) Continuing patches for GeneralizedTime. Fix up certificate and CRL ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. Removed the versions check from X509 routines when loading extensions: this allows certain broken certificates that don't set the version properly to be processed. [Steve Henson] *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which can still be regenerated with "make depend". [Ben Laurie] *) Spelling mistake in C version of CAST-128. [Ben Laurie, reported by Jeremy Hylton ] *) Changes to the error generation code. The perl script err-code.pl now reads in the old error codes and retains the old numbers, only adding new ones if necessary. It also only changes the .err files if new codes are added. The makefiles have been modified to only insert errors when needed (to avoid needlessly modifying header files). This is done by only inserting errors if the .err file is newer than the auto generated C file. To rebuild all the error codes from scratch (the old behaviour) either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl or delete all the .err files. [Steve Henson] *) CAST-128 was incorrectly implemented for short keys. The C version has been fixed, but is untested. The assembler versions are also fixed, but new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing to regenerate it if needed. [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun Hagino ] *) File was opened incorrectly in randfile.c. [Ulf Möller ] *) Beginning of support for GeneralizedTime. d2i, i2d, check and print functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or GeneralizedTime. ASN1_TIME is the proper type used in certificates et al: it's just almost always a UTCTime. Note this patch adds new error codes so do a "make errors" if there are problems. [Steve Henson] *) Correct Linux 1 recognition in config. [Ulf Möller ] *) Remove pointless MD5 hash when using DSA keys in ca. [Anonymous ] *) Generate an error if given an empty string as a cert directory. Also generate an error if handed NULL (previously returned 0 to indicate an error, but didn't set one). [Ben Laurie, reported by Anonymous ] *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last. [Ben Laurie] *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct parameters. This was causing a warning which killed off the Win32 compile. [Steve Henson] *) Remove C++ style comments from crypto/bn/bn_local.h. [Neil Costigan ] *) The function OBJ_txt2nid was broken. It was supposed to return a nid based on a text string, looking up short and long names and finally "dot" format. The "dot" format stuff didn't work. Added new function OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the OID is not part of the table. [Steve Henson] *) Add prototypes to X509 lookup/verify methods, fixing a bug in X509_LOOKUP_by_alias(). [Ben Laurie] *) Sort openssl functions by name. [Ben Laurie] *) Get the gendsa program working (hopefully) and add it to app list. Remove encryption from sample DSA keys (in case anyone is interested the password was "1234"). [Steve Henson] *) Make _all_ *_free functions accept a NULL pointer. [Frans Heymans ] *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use NULL pointers. [Anonymous ] *) s_server should send the CAfile as acceptable CAs, not its own cert. [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] *) Don't blow it for numeric -newkey arguments to apps/req. [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] *) Temp key "for export" tests were wrong in s3_srvr.c. [Anonymous ] *) Add prototype for temp key callback functions SSL_CTX_set_tmp_{rsa,dh}_callback(). [Ben Laurie] *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey(). [Steve Henson] *) X509_name_add_entry() freed the wrong thing after an error. [Arne Ansper ] *) rsa_eay.c would attempt to free a NULL context. [Arne Ansper ] *) BIO_s_socket() had a broken should_retry() on Windoze. [Arne Ansper ] *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH. [Arne Ansper ] *) Make sure the already existing X509_STORE->depth variable is initialized in X509_STORE_new(), but document the fact that this variable is still unused in the certificate verification process. [Ralf S. Engelschall] *) Fix the various library and apps files to free up pkeys obtained from X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions. [Steve Henson] *) Fix reference counting in X509_PUBKEY_get(). This makes demos/maurice/example2.c work, amongst others, probably. [Steve Henson and Ben Laurie] *) First cut of a cleanup for apps/. First the `ssleay' program is now named `openssl' and second, the shortcut symlinks for the `openssl ' are no longer created. This way we have a single and consistent command line interface `openssl ', similar to `cvs '. [Ralf S. Engelschall, Paul Sutton and Ben Laurie] *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey BIT STRING wrapper always have zero unused bits. [Steve Henson] *) Add CA.pl, perl version of CA.sh, add extended key usage OID. [Steve Henson] *) Make the top-level INSTALL documentation easier to understand. [Paul Sutton] *) Makefiles updated to exit if an error occurs in a sub-directory make (including if user presses ^C) [Paul Sutton] *) Make Montgomery context stuff explicit in RSA data structure. [Ben Laurie] *) Fix build order of pem and err to allow for generated pem.h. [Ben Laurie] *) Fix renumbering bug in X509_NAME_delete_entry(). [Ben Laurie] *) Enhanced the err-ins.pl script so it makes the error library number global and can add a library name. This is needed for external ASN1 and other error libraries. [Steve Henson] *) Fixed sk_insert which never worked properly. [Steve Henson] *) Fix ASN1 macros so they can handle indefinite length construted EXPLICIT tags. Some non standard certificates use these: they can now be read in. [Steve Henson] *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc) into a single doc/ssleay.txt bundle. This way the information is still preserved but no longer messes up this directory. Now it's new room for the new set of documenation files. [Ralf S. Engelschall] *) SETs were incorrectly DER encoded. This was a major pain, because they shared code with SEQUENCEs, which aren't coded the same. This means that almost everything to do with SETs or SEQUENCEs has either changed name or number of arguments. [Ben Laurie, based on a partial fix by GP Jayan ] *) Fix test data to work with the above. [Ben Laurie] *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but was already fixed by Eric for 0.9.1 it seems. [Ben Laurie - pointed out by Ulf Möller ] *) Autodetect FreeBSD3. [Ben Laurie] *) Fix various bugs in Configure. This affects the following platforms: nextstep ncr-scde unixware-2.0 unixware-2.0-pentium sco5-cc. [Ben Laurie] *) Eliminate generated files from CVS. Reorder tests to regenerate files before they are needed. [Ben Laurie] *) Generate Makefile.ssl from Makefile.org (to keep CVS happy). [Ben Laurie] Changes between 0.9.1b and 0.9.1c [23-Dec-1998] *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and changed SSLeay to OpenSSL in version strings. [Ralf S. Engelschall] *) Some fixups to the top-level documents. [Paul Sutton] *) Fixed the nasty bug where rsaref.h was not found under compile-time because the symlink to include/ was missing. [Ralf S. Engelschall] *) Incorporated the popular no-RSA/DSA-only patches which allow to compile a RSA-free SSLeay. [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall] *) Fixed nasty rehash problem under `make -f Makefile.ssl links' when "ssleay" is still not found. [Ralf S. Engelschall] *) Added more platforms to Configure: Cray T3E, HPUX 11, [Ralf S. Engelschall, Beckmann ] *) Updated the README file. [Ralf S. Engelschall] *) Added various .cvsignore files in the CVS repository subdirs to make a "cvs update" really silent. [Ralf S. Engelschall] *) Recompiled the error-definition header files and added missing symbols to the Win32 linker tables. [Ralf S. Engelschall] *) Cleaned up the top-level documents; o new files: CHANGES and LICENSE o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay o merged COPYRIGHT into LICENSE o removed obsolete TODO file o renamed MICROSOFT to INSTALL.W32 [Ralf S. Engelschall] *) Removed dummy files from the 0.9.1b source tree: crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f [Ralf S. Engelschall] *) Added various platform portability fixes. [Mark J. Cox] *) The Genesis of the OpenSSL rpject: We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A. Young and Tim J. Hudson created while they were working for C2Net until summer 1998. [The OpenSSL Project] Changes between 0.9.0b and 0.9.1b [not released] *) Updated a few CA certificates under certs/ [Eric A. Young] *) Changed some BIGNUM api stuff. [Eric A. Young] *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD, DGUX x86, Linux Alpha, etc. [Eric A. Young] *) New COMP library [crypto/comp/] for SSL Record Layer Compression: RLE (dummy implemented) and ZLIB (really implemented when ZLIB is available). [Eric A. Young] *) Add -strparse option to asn1pars program which parses nested binary structures [Dr Stephen Henson ] *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs. [Eric A. Young] *) DSA fix for "ca" program. [Eric A. Young] *) Added "-genkey" option to "dsaparam" program. [Eric A. Young] *) Added RIPE MD160 (rmd160) message digest. [Eric A. Young] *) Added -a (all) option to "ssleay version" command. [Eric A. Young] *) Added PLATFORM define which is the id given to Configure. [Eric A. Young] *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking. [Eric A. Young] *) Extended the ASN.1 parser routines. [Eric A. Young] *) Extended BIO routines to support REUSEADDR, seek, tell, etc. [Eric A. Young] *) Added a BN_CTX to the BN library. [Eric A. Young] *) Fixed the weak key values in DES library [Eric A. Young] *) Changed API in EVP library for cipher aliases. [Eric A. Young] *) Added support for RC2/64bit cipher. [Eric A. Young] *) Converted the lhash library to the crypto/mem.c functions. [Eric A. Young] *) Added more recognized ASN.1 object ids. [Eric A. Young] *) Added more RSA padding checks for SSL/TLS. [Eric A. Young] *) Added BIO proxy/filter functionality. [Eric A. Young] *) Added extra_certs to SSL_CTX which can be used send extra CA certificates to the client in the CA cert chain sending process. It can be configured with SSL_CTX_add_extra_chain_cert(). [Eric A. Young] *) Now Fortezza is denied in the authentication phase because this is key exchange mechanism is not supported by SSLeay at all. [Eric A. Young] *) Additional PKCS1 checks. [Eric A. Young] *) Support the string "TLSv1" for all TLS v1 ciphers. [Eric A. Young] *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the ex_data index of the SSL context in the X509_STORE_CTX ex_data. [Eric A. Young] *) Fixed a few memory leaks. [Eric A. Young] *) Fixed various code and comment typos. [Eric A. Young] *) A minor bug in ssl/s3_clnt.c where there would always be 4 0 bytes sent in the client random.

Be sure to read the -documentation of the application you want to use. The INSTALL file -explains how to install this library. - -OpenSSL includes a command line utility that can be used to perform a -variety of cryptographic functions. It is described in the openssl(1) -manpage. Documentation for developers is currently being written. Many -manual pages are available; overviews over libcrypto and -libssl are given in the crypto(3) and ssl(3) manpages. - -The OpenSSL manpages are installed in /usr/local/ssl/man/ (or a -different directory if you specified one as described in INSTALL). -In addition, you can read the most current versions at -. Note that the online documents refer -to the very latest development versions of OpenSSL and may include features -not present in released versions. If in doubt refer to the documentation -that came with the version of OpenSSL you are using. The pod format -documentation is included in each OpenSSL distribution under the docs -directory. - -There is some documentation about certificate extensions and PKCS#12 -in doc/openssl.txt - -The original SSLeay documentation is included in OpenSSL as -doc/ssleay.txt. It may be useful when none of the other resources -help, but please note that it reflects the obsolete version SSLeay -0.6.6. - - -* How can I contact the OpenSSL developers? - -The README file describes how to submit bug reports and patches to -OpenSSL. Information on the OpenSSL mailing lists is available from -. - - -* Where can I get a compiled version of OpenSSL? - -You can finder pointers to binary distributions in - . - -Some applications that use OpenSSL are distributed in binary form. -When using such an application, you don't need to install OpenSSL -yourself; the application will include the required parts (e.g. DLLs). - -If you want to build OpenSSL on a Windows system and you don't have -a C compiler, read the "Mingw32" section of INSTALL.W32 for information -on how to obtain and install the free GNU C compiler. - -A number of Linux and *BSD distributions include OpenSSL. - - -* Why aren't tools like 'autoconf' and 'libtool' used? - -autoconf will probably be used in future OpenSSL versions. If it was -less Unix-centric, it might have been used much earlier. - -* What is an 'engine' version? - -With version 0.9.6 OpenSSL was extended to interface to external crypto -hardware. This was realized in a special release '0.9.6-engine'. With -version 0.9.7 the changes were merged into the main development line, -so that the special release is no longer necessary. - -* How do I check the authenticity of the OpenSSL distribution? - -We provide MD5 digests and ASC signatures of each tarball. -Use MD5 to check that a tarball from a mirror site is identical: - - md5sum TARBALL | awk '{print $1;}' | cmp - TARBALL.md5 - -You can check authenticity using pgp or gpg. You need the OpenSSL team -member public key used to sign it (download it from a key server, see a -list of keys at ). Then -just do: - - pgp TARBALL.asc - -* How does the versioning scheme work? - -After the release of OpenSSL 1.0.0 the versioning scheme changed. Letter -releases (e.g. 1.0.1a) can only contain bug and security fixes and no -new features. Minor releases change the last number (e.g. 1.0.2) and -can contain new features that retain binary compatibility. Changes to -the middle number are considered major releases and neither source nor -binary compatibility is guaranteed. - -Therefore the answer to the common question "when will feature X be -backported to OpenSSL 1.0.0/0.9.8?" is "never" but it could appear -in the next minor release. - -[LEGAL] ======================================================================= - -* Do I need patent licenses to use OpenSSL? - -The patents section of the README file lists patents that may apply to -you if you want to use OpenSSL. For information on intellectual -property rights, please consult a lawyer. The OpenSSL team does not -offer legal advice. - -You can configure OpenSSL so as not to use IDEA, MDC2 and RC5 by using - ./config no-idea no-mdc2 no-rc5 - - -* Can I use OpenSSL with GPL software? - -On many systems including the major Linux and BSD distributions, yes (the -GPL does not place restrictions on using libraries that are part of the -normal operating system distribution). - -On other systems, the situation is less clear. Some GPL software copyright -holders claim that you infringe on their rights if you use OpenSSL with -their software on operating systems that don't normally include OpenSSL. - -If you develop open source software that uses OpenSSL, you may find it -useful to choose an other license than the GPL, or state explicitly that -"This program is released under the GPL with the additional exemption that -compiling, linking, and/or using OpenSSL is allowed." If you are using -GPL software developed by others, you may want to ask the copyright holder -for permission to use their software with OpenSSL. - - -[USER] ======================================================================== - -* Why do I get a "PRNG not seeded" error message? - -Cryptographic software needs a source of unpredictable data to work -correctly. Many open source operating systems provide a "randomness -device" (/dev/urandom or /dev/random) that serves this purpose. -All OpenSSL versions try to use /dev/urandom by default; starting with -version 0.9.7, OpenSSL also tries /dev/random if /dev/urandom is not -available. - -On other systems, applications have to call the RAND_add() or -RAND_seed() function with appropriate data before generating keys or -performing public key encryption. (These functions initialize the -pseudo-random number generator, PRNG.) Some broken applications do -not do this. As of version 0.9.5, the OpenSSL functions that need -randomness report an error if the random number generator has not been -seeded with at least 128 bits of randomness. If this error occurs and -is not discussed in the documentation of the application you are -using, please contact the author of that application; it is likely -that it never worked correctly. OpenSSL 0.9.5 and later make the -error visible by refusing to perform potentially insecure encryption. - -If you are using Solaris 8, you can add /dev/urandom and /dev/random -devices by installing patch 112438 (Sparc) or 112439 (x86), which are -available via the Patchfinder at -(Solaris 9 includes these devices by default). For /dev/random support -for earlier Solaris versions, see Sun's statement at - -(the SUNWski package is available in patch 105710). - -On systems without /dev/urandom and /dev/random, it is a good idea to -use the Entropy Gathering Demon (EGD); see the RAND_egd() manpage for -details. Starting with version 0.9.7, OpenSSL will automatically look -for an EGD socket at /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool and -/etc/entropy. - -Most components of the openssl command line utility automatically try -to seed the random number generator from a file. The name of the -default seeding file is determined as follows: If environment variable -RANDFILE is set, then it names the seeding file. Otherwise if -environment variable HOME is set, then the seeding file is $HOME/.rnd. -If neither RANDFILE nor HOME is set, versions up to OpenSSL 0.9.6 will -use file .rnd in the current directory while OpenSSL 0.9.6a uses no -default seeding file at all. OpenSSL 0.9.6b and later will behave -similarly to 0.9.6a, but will use a default of "C:\" for HOME on -Windows systems if the environment variable has not been set. - -If the default seeding file does not exist or is too short, the "PRNG -not seeded" error message may occur. - -The openssl command line utility will write back a new state to the -default seeding file (and create this file if necessary) unless -there was no sufficient seeding. - -Pointing $RANDFILE to an Entropy Gathering Daemon socket does not work. -Use the "-rand" option of the OpenSSL command line tools instead. -The $RANDFILE environment variable and $HOME/.rnd are only used by the -OpenSSL command line tools. Applications using the OpenSSL library -provide their own configuration options to specify the entropy source, -please check out the documentation coming the with application. - - -* Why do I get an "unable to write 'random state'" error message? - - -Sometimes the openssl command line utility does not abort with -a "PRNG not seeded" error message, but complains that it is -"unable to write 'random state'". This message refers to the -default seeding file (see previous answer). A possible reason -is that no default filename is known because neither RANDFILE -nor HOME is set. (Versions up to 0.9.6 used file ".rnd" in the -current directory in this case, but this has changed with 0.9.6a.) - - -* How do I create certificates or certificate requests? - -Check out the CA.pl(1) manual page. This provides a simple wrapper round -the 'req', 'verify', 'ca' and 'pkcs12' utilities. For finer control check -out the manual pages for the individual utilities and the certificate -extensions documentation (in ca(1), req(1), x509v3_config(5) ) - - -* Why can't I create certificate requests? - -You typically get the error: - - unable to find 'distinguished_name' in config - problems making Certificate Request - -This is because it can't find the configuration file. Check out the -DIAGNOSTICS section of req(1) for more information. - - -* Why does fail with a certificate verify error? - -This problem is usually indicated by log messages saying something like -"unable to get local issuer certificate" or "self signed certificate". -When a certificate is verified its root CA must be "trusted" by OpenSSL -this typically means that the CA certificate must be placed in a directory -or file and the relevant program configured to read it. The OpenSSL program -'verify' behaves in a similar way and issues similar error messages: check -the verify(1) program manual page for more information. - - -* Why can I only use weak ciphers when I connect to a server using OpenSSL? - -This is almost certainly because you are using an old "export grade" browser -which only supports weak encryption. Upgrade your browser to support 128 bit -ciphers. - - -* How can I create DSA certificates? - -Check the CA.pl(1) manual page for a DSA certificate example. - - -* Why can't I make an SSL connection to a server using a DSA certificate? - -Typically you'll see a message saying there are no shared ciphers when -the same setup works fine with an RSA certificate. There are two possible -causes. The client may not support connections to DSA servers most web -browsers (including Netscape and MSIE) only support connections to servers -supporting RSA cipher suites. The other cause is that a set of DH parameters -has not been supplied to the server. DH parameters can be created with the -dhparam(1) command and loaded using the SSL_CTX_set_tmp_dh() for example: -check the source to s_server in apps/s_server.c for an example. - - -* How can I remove the passphrase on a private key? - -Firstly you should be really *really* sure you want to do this. Leaving -a private key unencrypted is a major security risk. If you decide that -you do have to do this check the EXAMPLES sections of the rsa(1) and -dsa(1) manual pages. - - -* Why can't I use OpenSSL certificates with SSL client authentication? - -What will typically happen is that when a server requests authentication -it will either not include your certificate or tell you that you have -no client certificates (Netscape) or present you with an empty list box -(MSIE). The reason for this is that when a server requests a client -certificate it includes a list of CAs names which it will accept. Browsers -will only let you select certificates from the list on the grounds that -there is little point presenting a certificate which the server will -reject. - -The solution is to add the relevant CA certificate to your servers "trusted -CA list". How you do this depends on the server software in uses. You can -print out the servers list of acceptable CAs using the OpenSSL s_client tool: - -openssl s_client -connect www.some.host:443 -prexit - -If your server only requests certificates on certain URLs then you may need -to manually issue an HTTP GET command to get the list when s_client connects: - -GET /some/page/needing/a/certificate.html - -If your CA does not appear in the list then this confirms the problem. - - -* Why does my browser give a warning about a mismatched hostname? - -Browsers expect the server's hostname to match the value in the commonName -(CN) field of the certificate. If it does not then you get a warning. - - -* How do I install a CA certificate into a browser? - -The usual way is to send the DER encoded certificate to the browser as -MIME type application/x-x509-ca-cert, for example by clicking on an appropriate -link. On MSIE certain extensions such as .der or .cacert may also work, or you -can import the certificate using the certificate import wizard. - -You can convert a certificate to DER form using the command: - -openssl x509 -in ca.pem -outform DER -out ca.der - -Occasionally someone suggests using a command such as: - -openssl pkcs12 -export -out cacert.p12 -in cacert.pem -inkey cakey.pem - -DO NOT DO THIS! This command will give away your CAs private key and -reduces its security to zero: allowing anyone to forge certificates in -whatever name they choose. - -* Why is OpenSSL x509 DN output not conformant to RFC2253? - -The ways to print out the oneline format of the DN (Distinguished Name) have -been extended in version 0.9.7 of OpenSSL. Using the new X509_NAME_print_ex() -interface, the "-nameopt" option could be introduded. See the manual -page of the "openssl x509" commandline tool for details. The old behaviour -has however been left as default for the sake of compatibility. - -* What is a "128 bit certificate"? Can I create one with OpenSSL? - -The term "128 bit certificate" is a highly misleading marketing term. It does -*not* refer to the size of the public key in the certificate! A certificate -containing a 128 bit RSA key would have negligible security. - -There were various other names such as "magic certificates", "SGC -certificates", "step up certificates" etc. - -You can't generally create such a certificate using OpenSSL but there is no -need to any more. Nowadays web browsers using unrestricted strong encryption -are generally available. - -When there were tight restrictions on the export of strong encryption -software from the US only weak encryption algorithms could be freely exported -(initially 40 bit and then 56 bit). It was widely recognised that this was -inadequate. A relaxation of the rules allowed the use of strong encryption but -only to an authorised server. - -Two slighly different techniques were developed to support this, one used by -Netscape was called "step up", the other used by MSIE was called "Server Gated -Cryptography" (SGC). When a browser initially connected to a server it would -check to see if the certificate contained certain extensions and was issued by -an authorised authority. If these test succeeded it would reconnect using -strong encryption. - -Only certain (initially one) certificate authorities could issue the -certificates and they generally cost more than ordinary certificates. - -Although OpenSSL can create certificates containing the appropriate extensions -the certificate would not come from a permitted authority and so would not -be recognized. - -The export laws were later changed to allow almost unrestricted use of strong -encryption so these certificates are now obsolete. - - -* Why does OpenSSL set the authority key identifier (AKID) extension incorrectly? - -It doesn't: this extension is often the cause of confusion. - -Consider a certificate chain A->B->C so that A signs B and B signs C. Suppose -certificate C contains AKID. - -The purpose of this extension is to identify the authority certificate B. This -can be done either by including the subject key identifier of B or its issuer -name and serial number. - -In this latter case because it is identifying certifcate B it must contain the -issuer name and serial number of B. - -It is often wrongly assumed that it should contain the subject name of B. If it -did this would be redundant information because it would duplicate the issuer -name of C. - - -* How can I set up a bundle of commercial root CA certificates? - -The OpenSSL software is shipped without any root CA certificate as the -OpenSSL project does not have any policy on including or excluding -any specific CA and does not intend to set up such a policy. Deciding -about which CAs to support is up to application developers or -administrators. - -Other projects do have other policies so you can for example extract the CA -bundle used by Mozilla and/or modssl as described in this article: - - - - -[BUILD] ======================================================================= - -* Why does the linker complain about undefined symbols? - -Maybe the compilation was interrupted, and make doesn't notice that -something is missing. Run "make clean; make". - -If you used ./Configure instead of ./config, make sure that you -selected the right target. File formats may differ slightly between -OS versions (for example sparcv8/sparcv9, or a.out/elf). - -In case you get errors about the following symbols, use the config -option "no-asm", as described in INSTALL: - - BF_cbc_encrypt, BF_decrypt, BF_encrypt, CAST_cbc_encrypt, - CAST_decrypt, CAST_encrypt, RC4, RC5_32_cbc_encrypt, RC5_32_decrypt, - RC5_32_encrypt, bn_add_words, bn_div_words, bn_mul_add_words, - bn_mul_comba4, bn_mul_comba8, bn_mul_words, bn_sqr_comba4, - bn_sqr_comba8, bn_sqr_words, bn_sub_words, des_decrypt3, - des_ede3_cbc_encrypt, des_encrypt, des_encrypt2, des_encrypt3, - des_ncbc_encrypt, md5_block_asm_host_order, sha1_block_asm_data_order - -If none of these helps, you may want to try using the current snapshot. -If the problem persists, please submit a bug report. - - -* Why does the OpenSSL test fail with "bc: command not found"? - -You didn't install "bc", the Unix calculator. If you want to run the -tests, get GNU bc from ftp://ftp.gnu.org or from your OS distributor. - - -* Why does the OpenSSL test fail with "bc: 1 no implemented"? - -On some SCO installations or versions, bc has a bug that gets triggered -when you run the test suite (using "make test"). The message returned is -"bc: 1 not implemented". - -The best way to deal with this is to find another implementation of bc -and compile/install it. GNU bc (see -for download instructions) can be safely used, for example. - - -* Why does the OpenSSL test fail with "bc: stack empty"? - -On some DG/ux versions, bc seems to have a too small stack for calculations -that the OpenSSL bntest throws at it. This gets triggered when you run the -test suite (using "make test"). The message returned is "bc: stack empty". - -The best way to deal with this is to find another implementation of bc -and compile/install it. GNU bc (see -for download instructions) can be safely used, for example. - - -* Why does the OpenSSL compilation fail on Alpha Tru64 Unix? - -On some Alpha installations running Tru64 Unix and Compaq C, the compilation -of crypto/sha/sha_dgst.c fails with the message 'Fatal: Insufficient virtual -memory to continue compilation.' As far as the tests have shown, this may be -a compiler bug. What happens is that it eats up a lot of resident memory -to build something, probably a table. The problem is clearly in the -optimization code, because if one eliminates optimization completely (-O0), -the compilation goes through (and the compiler consumes about 2MB of resident -memory instead of 240MB or whatever one's limit is currently). - -There are three options to solve this problem: - -1. set your current data segment size soft limit higher. Experience shows -that about 241000 kbytes seems to be enough on an AlphaServer DS10. You do -this with the command 'ulimit -Sd nnnnnn', where 'nnnnnn' is the number of -kbytes to set the limit to. - -2. If you have a hard limit that is lower than what you need and you can't -get it changed, you can compile all of OpenSSL with -O0 as optimization -level. This is however not a very nice thing to do for those who expect to -get the best result from OpenSSL. A bit more complicated solution is the -following: - ------ snip:start ----- - make DIRS=crypto SDIRS=sha "`grep '^CFLAG=' Makefile.ssl | \ - sed -e 's/ -O[0-9] / -O0 /'`" - rm `ls crypto/*.o crypto/sha/*.o | grep -v 'sha_dgst\.o'` - make ------ snip:end ----- - -This will only compile sha_dgst.c with -O0, the rest with the optimization -level chosen by the configuration process. When the above is done, do the -test and installation and you're set. - -3. Reconfigure the toolkit with no-sha0 option to leave out SHA0. It -should not be used and is not used in SSL/TLS nor any other recognized -protocol in either case. - - -* Why does the OpenSSL compilation fail with "ar: command not found"? - -Getting this message is quite usual on Solaris 2, because Sun has hidden -away 'ar' and other development commands in directories that aren't in -$PATH by default. One of those directories is '/usr/ccs/bin'. The -quickest way to fix this is to do the following (it assumes you use sh -or any sh-compatible shell): - ------ snip:start ----- - PATH=${PATH}:/usr/ccs/bin; export PATH ------ snip:end ----- - -and then redo the compilation. What you should really do is make sure -'/usr/ccs/bin' is permanently in your $PATH, for example through your -'.profile' (again, assuming you use a sh-compatible shell). - - -* Why does the OpenSSL compilation fail on Win32 with VC++? - -Sometimes, you may get reports from VC++ command line (cl) that it -can't find standard include files like stdio.h and other weirdnesses. -One possible cause is that the environment isn't correctly set up. -To solve that problem for VC++ versions up to 6, one should run -VCVARS32.BAT which is found in the 'bin' subdirectory of the VC++ -installation directory (somewhere under 'Program Files'). For VC++ -version 7 (and up?), which is also called VS.NET, the file is called -VSVARS32.BAT instead. -This needs to be done prior to running NMAKE, and the changes are only -valid for the current DOS session. - - -* What is special about OpenSSL on Redhat? - -Red Hat Linux (release 7.0 and later) include a preinstalled limited -version of OpenSSL. For patent reasons, support for IDEA, RC5 and MDC2 -is disabled in this version. The same may apply to other Linux distributions. -Users may therefore wish to install more or all of the features left out. - -To do this you MUST ensure that you do not overwrite the openssl that is in -/usr/bin on your Red Hat machine. Several packages depend on this file, -including sendmail and ssh. /usr/local/bin is a good alternative choice. The -libraries that come with Red Hat 7.0 onwards have different names and so are -not affected. (eg For Red Hat 7.2 they are /lib/libssl.so.0.9.6b and -/lib/libcrypto.so.0.9.6b with symlinks /lib/libssl.so.2 and -/lib/libcrypto.so.2 respectively). - -Please note that we have been advised by Red Hat attempting to recompile the -openssl rpm with all the cryptography enabled will not work. All other -packages depend on the original Red Hat supplied openssl package. It is also -worth noting that due to the way Red Hat supplies its packages, updates to -openssl on each distribution never change the package version, only the -build number. For example, on Red Hat 7.1, the latest openssl package has -version number 0.9.6 and build number 9 even though it contains all the -relevant updates in packages up to and including 0.9.6b. - -A possible way around this is to persuade Red Hat to produce a non-US -version of Red Hat Linux. - -FYI: Patent numbers and expiry dates of US patents: -MDC-2: 4,908,861 13/03/2007 -IDEA: 5,214,703 25/05/2010 -RC5: 5,724,428 03/03/2015 - - -* Why does the OpenSSL compilation fail on MacOS X? - -If the failure happens when trying to build the "openssl" binary, with -a large number of undefined symbols, it's very probable that you have -OpenSSL 0.9.6b delivered with the operating system (you can find out by -running '/usr/bin/openssl version') and that you were trying to build -OpenSSL 0.9.7 or newer. The problem is that the loader ('ld') in -MacOS X has a misfeature that's quite difficult to go around. -Look in the file PROBLEMS for a more detailed explanation and for possible -solutions. - - -* Why does the OpenSSL test suite fail on MacOS X? - -If the failure happens when running 'make test' and the RC4 test fails, -it's very probable that you have OpenSSL 0.9.6b delivered with the -operating system (you can find out by running '/usr/bin/openssl version') -and that you were trying to build OpenSSL 0.9.6d. The problem is that -the loader ('ld') in MacOS X has a misfeature that's quite difficult to -go around and has linked the programs "openssl" and the test programs -with /usr/lib/libcrypto.dylib and /usr/lib/libssl.dylib instead of the -libraries you just built. -Look in the file PROBLEMS for a more detailed explanation and for possible -solutions. - -* Why does the OpenSSL test suite fail in BN_sqr test [on a 64-bit platform]? - -Failure in BN_sqr test is most likely caused by a failure to configure the -toolkit for current platform or lack of support for the platform in question. -Run './config -t' and './apps/openssl version -p'. Do these platform -identifiers match? If they don't, then you most likely failed to run -./config and you're hereby advised to do so before filing a bug report. -If ./config itself fails to run, then it's most likely problem with your -local environment and you should turn to your system administrator (or -similar). If identifiers match (and/or no alternative identifier is -suggested by ./config script), then the platform is unsupported. There might -or might not be a workaround. Most notably on SPARC64 platforms with GNU -C compiler you should be able to produce a working build by running -'./config -m32'. I understand that -m32 might not be what you want/need, -but the build should be operational. For further details turn to -. - -* Why does OpenBSD-i386 build fail on des-586.s with "Unimplemented segment type"? - -As of 0.9.7 assembler routines were overhauled for position independence -of the machine code, which is essential for shared library support. For -some reason OpenBSD is equipped with an out-of-date GNU assembler which -finds the new code offensive. To work around the problem, configure with -no-asm (and sacrifice a great deal of performance) or patch your assembler -according to . -For your convenience a pre-compiled replacement binary is provided at -. -Reportedly elder *BSD a.out platforms also suffer from this problem and -remedy should be same. Provided binary is statically linked and should be -working across wider range of *BSD branches, not just OpenBSD. - -* Why does the OpenSSL test suite fail in sha512t on x86 CPU? - -If the test program in question fails withs SIGILL, Illegal Instruction -exception, then you more than likely to run SSE2-capable CPU, such as -Intel P4, under control of kernel which does not support SSE2 -instruction extentions. See accompanying INSTALL file and -OPENSSL_ia32cap(3) documentation page for further information. - -* Why does compiler fail to compile sha512.c? - -OpenSSL SHA-512 implementation depends on compiler support for 64-bit -integer type. Few elder compilers [ULTRIX cc, SCO compiler to mention a -couple] lack support for this and therefore are incapable of compiling -the module in question. The recommendation is to disable SHA-512 by -adding no-sha512 to ./config [or ./Configure] command line. Another -possible alternative might be to switch to GCC. - -* Test suite still fails, what to do? - -Another common reason for failure to complete some particular test is -simply bad code generated by a buggy component in toolchain or deficiency -in run-time environment. There are few cases documented in PROBLEMS file, -consult it for possible workaround before you beat the drum. Even if you -don't find solution or even mention there, do reserve for possibility of -a compiler bug. Compiler bugs might appear in rather bizarre ways, they -never make sense, and tend to emerge when you least expect them. In order -to identify one, drop optimization level, e.g. by editing CFLAG line in -top-level Makefile, recompile and re-run the test. - -* I think I've found a bug, what should I do? - -If you are a new user then it is quite likely you haven't found a bug and -something is happening you aren't familiar with. Check this FAQ, the associated -documentation and the mailing lists for similar queries. If you are still -unsure whether it is a bug or not submit a query to the openssl-users mailing -list. - - -* I'm SURE I've found a bug, how do I report it? - -Bug reports with no security implications should be sent to the request -tracker. This can be done by mailing the report to (or its -alias ), please note that messages sent to the -request tracker also appear in the public openssl-dev mailing list. - -The report should be in plain text. Any patches should be sent as -plain text attachments because some mailers corrupt patches sent inline. -If your issue affects multiple versions of OpenSSL check any patches apply -cleanly and, if possible include patches to each affected version. - -The report should be given a meaningful subject line briefly summarising the -issue. Just "bug in OpenSSL" or "bug in OpenSSL 0.9.8n" is not very helpful. - -By sending reports to the request tracker the bug can then be given a priority -and assigned to the appropriate maintainer. The history of discussions can be -accessed and if the issue has been addressed or a reason why not. If patches -are only sent to openssl-dev they can be mislaid if a team member has to -wade through months of old messages to review the discussion. - -See also - - -* I've found a security issue, how do I report it? - -If you think your bug has security implications then please send it to -openssl-security@openssl.org if you don't get a prompt reply at least -acknowledging receipt then resend or mail it directly to one of the -more active team members (e.g. Steve). - -Note that bugs only present in the openssl utility are not in general -considered to be security issues. - -[PROG] ======================================================================== - -* Is OpenSSL thread-safe? - -Yes (with limitations: an SSL connection may not concurrently be used -by multiple threads). On Windows and many Unix systems, OpenSSL -automatically uses the multi-threaded versions of the standard -libraries. If your platform is not one of these, consult the INSTALL -file. - -Multi-threaded applications must provide two callback functions to -OpenSSL by calling CRYPTO_set_locking_callback() and -CRYPTO_set_id_callback(), for all versions of OpenSSL up to and -including 0.9.8[abc...]. As of version 1.0.0, CRYPTO_set_id_callback() -and associated APIs are deprecated by CRYPTO_THREADID_set_callback() -and friends. This is described in the threads(3) manpage. - -* I've compiled a program under Windows and it crashes: why? - -This is usually because you've missed the comment in INSTALL.W32. -Your application must link against the same version of the Win32 -C-Runtime against which your openssl libraries were linked. The -default version for OpenSSL is /MD - "Multithreaded DLL". - -If you are using Microsoft Visual C++'s IDE (Visual Studio), in -many cases, your new project most likely defaulted to "Debug -Singlethreaded" - /ML. This is NOT interchangeable with /MD and your -program will crash, typically on the first BIO related read or write -operation. - -For each of the six possible link stage configurations within Win32, -your application must link against the same by which OpenSSL was -built. If you are using MS Visual C++ (Studio) this can be changed -by: - - 1. Select Settings... from the Project Menu. - 2. Select the C/C++ Tab. - 3. Select "Code Generation from the "Category" drop down list box - 4. Select the Appropriate library (see table below) from the "Use - run-time library" drop down list box. Perform this step for both - your debug and release versions of your application (look at the - top left of the settings panel to change between the two) - - Single Threaded /ML - MS VC++ often defaults to - this for the release - version of a new project. - Debug Single Threaded /MLd - MS VC++ often defaults to - this for the debug version - of a new project. - Multithreaded /MT - Debug Multithreaded /MTd - Multithreaded DLL /MD - OpenSSL defaults to this. - Debug Multithreaded DLL /MDd - -Note that debug and release libraries are NOT interchangeable. If you -built OpenSSL with /MD your application must use /MD and cannot use /MDd. - -As per 0.9.8 the above limitation is eliminated for .DLLs. OpenSSL -.DLLs compiled with some specific run-time option [we insist on the -default /MD] can be deployed with application compiled with different -option or even different compiler. But there is a catch! Instead of -re-compiling OpenSSL toolkit, as you would have to with prior versions, -you have to compile small C snippet with compiler and/or options of -your choice. The snippet gets installed as -/include/openssl/applink.c and should be either added to -your application project or simply #include-d in one [and only one] -of your application source files. Failure to link this shim module -into your application manifests itself as fatal "no OPENSSL_Applink" -run-time error. An explicit reminder is due that in this situation -[mixing compiler options] it is as important to add CRYPTO_malloc_init -prior first call to OpenSSL. - -* How do I read or write a DER encoded buffer using the ASN1 functions? - -You have two options. You can either use a memory BIO in conjunction -with the i2d_*_bio() or d2i_*_bio() functions or you can use the -i2d_*(), d2i_*() functions directly. Since these are often the -cause of grief here are some code fragments using PKCS7 as an example: - - unsigned char *buf, *p; - int len; - - len = i2d_PKCS7(p7, NULL); - buf = OPENSSL_malloc(len); /* or Malloc, error checking omitted */ - p = buf; - i2d_PKCS7(p7, &p); - -At this point buf contains the len bytes of the DER encoding of -p7. - -The opposite assumes we already have len bytes in buf: - - unsigned char *p; - p = buf; - p7 = d2i_PKCS7(NULL, &p, len); - -At this point p7 contains a valid PKCS7 structure of NULL if an error -occurred. If an error occurred ERR_print_errors(bio) should give more -information. - -The reason for the temporary variable 'p' is that the ASN1 functions -increment the passed pointer so it is ready to read or write the next -structure. This is often a cause of problems: without the temporary -variable the buffer pointer is changed to point just after the data -that has been read or written. This may well be uninitialized data -and attempts to free the buffer will have unpredictable results -because it no longer points to the same address. - - -* OpenSSL uses DER but I need BER format: does OpenSSL support BER? - -The short answer is yes, because DER is a special case of BER and OpenSSL -ASN1 decoders can process BER. - -The longer answer is that ASN1 structures can be encoded in a number of -different ways. One set of ways is the Basic Encoding Rules (BER) with various -permissible encodings. A restriction of BER is the Distinguished Encoding -Rules (DER): these uniquely specify how a given structure is encoded. - -Therefore, because DER is a special case of BER, DER is an acceptable encoding -for BER. - - -* I've tried using and I get errors why? - -This usually happens when you try compiling something using the PKCS#12 -macros with a C++ compiler. There is hardly ever any need to use the -PKCS#12 macros in a program, it is much easier to parse and create -PKCS#12 files using the PKCS12_parse() and PKCS12_create() functions -documented in doc/openssl.txt and with examples in demos/pkcs12. The -'pkcs12' application has to use the macros because it prints out -debugging information. - - -* I've called and it fails, why? - -Before submitting a report or asking in one of the mailing lists, you -should try to determine the cause. In particular, you should call -ERR_print_errors() or ERR_print_errors_fp() after the failed call -and see if the message helps. Note that the problem may occur earlier -than you think -- you should check for errors after every call where -it is possible, otherwise the actual problem may be hidden because -some OpenSSL functions clear the error state. - - -* I just get a load of numbers for the error output, what do they mean? - -The actual format is described in the ERR_print_errors() manual page. -You should call the function ERR_load_crypto_strings() before hand and -the message will be output in text form. If you can't do this (for example -it is a pre-compiled binary) you can use the errstr utility on the error -code itself (the hex digits after the second colon). - - -* Why do I get errors about unknown algorithms? - -The cause is forgetting to load OpenSSL's table of algorithms with -OpenSSL_add_all_algorithms(). See the manual page for more information. This -can cause several problems such as being unable to read in an encrypted -PEM file, unable to decrypt a PKCS#12 file or signature failure when -verifying certificates. - -* Why can't the OpenSSH configure script detect OpenSSL? - -Several reasons for problems with the automatic detection exist. -OpenSSH requires at least version 0.9.5a of the OpenSSL libraries. -Sometimes the distribution has installed an older version in the system -locations that is detected instead of a new one installed. The OpenSSL -library might have been compiled for another CPU or another mode (32/64 bits). -Permissions might be wrong. - -The general answer is to check the config.log file generated when running -the OpenSSH configure script. It should contain the detailed information -on why the OpenSSL library was not detected or considered incompatible. - - -* Can I use OpenSSL's SSL library with non-blocking I/O? - -Yes; make sure to read the SSL_get_error(3) manual page! - -A pitfall to avoid: Don't assume that SSL_read() will just read from -the underlying transport or that SSL_write() will just write to it -- -it is also possible that SSL_write() cannot do any useful work until -there is data to read, or that SSL_read() cannot do anything until it -is possible to send data. One reason for this is that the peer may -request a new TLS/SSL handshake at any time during the protocol, -requiring a bi-directional message exchange; both SSL_read() and -SSL_write() will try to continue any pending handshake. - - -* Why doesn't my server application receive a client certificate? - -Due to the TLS protocol definition, a client will only send a certificate, -if explicitly asked by the server. Use the SSL_VERIFY_PEER flag of the -SSL_CTX_set_verify() function to enable the use of client certificates. - - -* Why does compilation fail due to an undefined symbol NID_uniqueIdentifier? - -For OpenSSL 0.9.7 the OID table was extended and corrected. In earlier -versions, uniqueIdentifier was incorrectly used for X.509 certificates. -The correct name according to RFC2256 (LDAP) is x500UniqueIdentifier. -Change your code to use the new name when compiling against OpenSSL 0.9.7. - - -* I think I've detected a memory leak, is this a bug? - -In most cases the cause of an apparent memory leak is an OpenSSL internal table -that is allocated when an application starts up. Since such tables do not grow -in size over time they are harmless. - -These internal tables can be freed up when an application closes using various -functions. Currently these include following: - -Thread-local cleanup functions: - - ERR_remove_state() - -Application-global cleanup functions that are aware of usage (and therefore -thread-safe): - - ENGINE_cleanup() and CONF_modules_unload() - -"Brutal" (thread-unsafe) Application-global cleanup functions: - - ERR_free_strings(), EVP_cleanup() and CRYPTO_cleanup_all_ex_data(). - - -* Why does Valgrind complain about the use of uninitialized data? - -When OpenSSL's PRNG routines are called to generate random numbers the supplied -buffer contents are mixed into the entropy pool: so it technically does not -matter whether the buffer is initialized at this point or not. Valgrind (and -other test tools) will complain about this. When using Valgrind, make sure the -OpenSSL library has been compiled with the PURIFY macro defined (-DPURIFY) -to get rid of these warnings. - - -* Why doesn't a memory BIO work when a file does? - -This can occur in several cases for example reading an S/MIME email message. -The reason is that a memory BIO can do one of two things when all the data -has been read from it. - -The default behaviour is to indicate that no more data is available and that -the call should be retried, this is to allow the application to fill up the BIO -again if necessary. - -Alternatively it can indicate that no more data is available and that EOF has -been reached. - -If a memory BIO is to behave in the same way as a file this second behaviour -is needed. This must be done by calling: - - BIO_set_mem_eof_return(bio, 0); - -See the manual pages for more details. - - -* Where are the declarations and implementations of d2i_X509() etc? - -These are defined and implemented by macros of the form: - - - DECLARE_ASN1_FUNCTIONS(X509) and IMPLEMENT_ASN1_FUNCTIONS(X509) - -The implementation passes an ASN1 "template" defining the structure into an -ASN1 interpreter using generalised functions such as ASN1_item_d2i(). - - -=============================================================================== +The FAQ is now maintained on the web: + https://www.openssl.org/docs/faq.html Index: vendor-crypto/openssl/dist-0.9.8/FREEBSD-Xlist =================================================================== --- vendor-crypto/openssl/dist-0.9.8/FREEBSD-Xlist (revision 291710) +++ vendor-crypto/openssl/dist-0.9.8/FREEBSD-Xlist (revision 291711) @@ -1,45 +1,46 @@ +openssl-*/.cvsignore openssl-*/INSTALL.DJGPP openssl-*/INSTALL.MacOS openssl-*/INSTALL.NW openssl-*/INSTALL.OS2 openssl-*/INSTALL.VMS openssl-*/INSTALL.W32 openssl-*/INSTALL.W64 openssl-*/INSTALL.WCE openssl-*/MacOS openssl-*/VMS openssl-*/Netware openssl-*/*.com openssl-*/*.bak openssl-*/*.def openssl-*/*.mak openssl-*/*/*.bat openssl-*/*/*.com openssl-*/*/*/*.bat openssl-*/*/*/*.com openssl-*/apps/openssl-vms.cnf openssl-*/crypto/bn/asm/vms.mar openssl-*/crypto/bn/vms-helper.c openssl-*/crypto/buildinf.h openssl-*/crypto/dso/dso_vms.c openssl-*/crypto/dso/dso_win32.c openssl-*/crypto/threads/solaris.sh openssl-*/demos/engines/rsaref openssl-*/ms openssl-*/op openssl-*/os2 openssl-*/perl openssl-*/shlib/Makefile.hpux10-cc openssl-*/shlib/hpux10-cc.sh openssl-*/shlib/irix.sh openssl-*/shlib/solaris-sc4.sh openssl-*/shlib/solaris.sh openssl-*/shlib/sun.sh openssl-*/shlib/sco5-shared-installed openssl-*/shlib/sco5-shared-gcc.sh openssl-*/shlib/sco5-shared.sh openssl-*/shlib/svr5-shared-gcc.sh openssl-*/shlib/svr5-shared-installed openssl-*/shlib/svr5-shared.sh openssl-*/util/cygwin.sh openssl-*/include Index: vendor-crypto/openssl/dist-0.9.8/FREEBSD-upgrade =================================================================== --- vendor-crypto/openssl/dist-0.9.8/FREEBSD-upgrade (revision 291710) +++ vendor-crypto/openssl/dist-0.9.8/FREEBSD-upgrade (revision 291711) @@ -1,83 +1,83 @@ This contains various notes used to import a new OpenSSL version into the FreeBSD base system.

DESCRIPTION ----------- The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, fully featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the OpenSSL toolkit and its related documentation. OpenSSL is based on the excellent SSLeay library developed from Eric A. Young and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the OpenSSL license plus the SSLeay license) situation, which basically means that you are free to get and use it for commercial and non-commercial purposes as long as you fulfill the conditions of both licenses. OVERVIEW -------- The OpenSSL toolkit includes: libssl.a: Implementation of SSLv2, SSLv3, TLSv1 and the required code to support both SSLv2, SSLv3 and TLSv1 in the one server and client. libcrypto.a: General encryption and X.509 v1/v3 stuff needed by SSL/TLS but not actually logically part of it. It includes routines for the following: Ciphers libdes - EAY's libdes DES encryption package which was floating around the net for a few years, and was then relicensed by him as part of SSLeay. It includes 15 'modes/variations' of DES (1, 2 and 3 key versions of ecb, cbc, cfb and ofb; pcbc and a more general form of cfb and ofb) including desx in cbc mode, a fast crypt(3), and routines to read passwords from the keyboard. RC4 encryption, RC2 encryption - 4 different modes, ecb, cbc, cfb and ofb. Blowfish encryption - 4 different modes, ecb, cbc, cfb and ofb. IDEA encryption - 4 different modes, ecb, cbc, cfb and ofb. Digests MD5 and MD2 message digest algorithms, fast implementations, SHA (SHA-0) and SHA-1 message digest algorithms, MDC2 message digest. A DES based hash that is popular on smart cards. Public Key RSA encryption/decryption/generation. There is no limit on the number of bits. DSA encryption/decryption/generation. There is no limit on the number of bits. Diffie-Hellman key-exchange/key generation. There is no limit on the number of bits. X.509v3 certificates X509 encoding/decoding into/from binary ASN1 and a PEM based ASCII-binary encoding which supports encryption with a private key. Program to generate RSA and DSA certificate requests and to generate RSA and DSA certificates. Systems The normal digital envelope routines and base64 encoding. Higher level access to ciphers and digests by name. New ciphers can be loaded at run time. The BIO io system which is a simple non-blocking IO abstraction. Current methods supported are file descriptors, sockets, socket accept, socket connect, memory buffer, buffering, SSL client/server, file pointer, encryption, digest, non-blocking testing and null. Data structures A dynamically growing hashing system A simple stack. A Configuration loader that uses a format similar to MS .ini files. openssl: A command line tool that can be used for: Creation of RSA, DH and DSA key parameters Creation of X.509 certificates, CSRs and CRLs Calculation of Message Digests Encryption and Decryption with Ciphers SSL/TLS Client and Server Tests Handling of S/MIME signed or encrypted mail PATENTS ------- Various companies hold various patents for various algorithms in various locations around the world. _YOU_ are responsible for ensuring that your use of any algorithms is legal by checking if there are any patents in your country. The file contains some of the patents that we know about or are rumored to exist. This is not a definitive list. RSA Security holds software patents on the RC5 algorithm. If you intend to use this cipher, you must contact RSA Security for licensing conditions. Their web page is http://www.rsasecurity.com/. RC4 is a trademark of RSA Security, so use of this label should perhaps only be used with RSA Security's permission. The IDEA algorithm is patented by Ascom in Austria, France, Germany, Italy, Japan, the Netherlands, Spain, Sweden, Switzerland, UK and the USA. They should be contacted if that algorithm is to be used; their web page is http://www.ascom.ch/. NTT and Mitsubishi have patents and pending patents on the Camellia algorithm, but allow use at no charge without requiring an explicit licensing agreement: http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html INSTALLATION ------------ To install this package under a Unix derivative, read the INSTALL file. For a Win32 platform, read the INSTALL.W32 file. For OpenVMS systems, read INSTALL.VMS. Read the documentation in the doc/ directory. It is quite rough, but it lists the functions; you will probably have to look at the code to work out how to use them. Look at the example programs. PROBLEMS -------- For some platforms, there are some known problems that may affect the user or application author. We try to collect those in doc/PROBLEMS, with current thoughts on how they should be solved in a future of OpenSSL. SUPPORT ------- See the OpenSSL website www.openssl.org for details of how to obtain commercial technical support. If you have any problems with OpenSSL then please take the following steps first: - Download the current snapshot from ftp://ftp.openssl.org/snapshot/ to see if the problem has already been addressed - Remove ASM versions of libraries - Remove compiler optimisation flags If you wish to report a bug then please include the following information in any bug report: - On Unix systems: Self-test report generated by 'make report' - On other systems: OpenSSL version: output of 'openssl version -a' OS Name, Version, Hardware platform Compiler Details (name, version) - Application Details (name, version) - Problem Description (steps that will reproduce the problem, if known) - Stack Traceback (if the application dumps core) Report the bug to the OpenSSL project via the Request Tracker (http://www.openssl.org/support/rt.html) by mail to: - openssl-bugs@openssl.org + rt@openssl.org - Note that the request tracker should NOT be used for general assistance - or support queries. Just because something doesn't work the way you expect - does not mean it is necessarily a bug in OpenSSL. + In order to avoid spam, this is a moderated mailing list, and it might + take a day for the ticket to show up.

If you do this, please also send + mail to rt@openssl.org with a link to the PR so that we can more easily + keep track of it. + HOW TO CONTRIBUTE TO OpenSSL ---------------------------- Development is coordinated on the openssl-dev mailing list (see http://www.openssl.org for information on subscribing). If you would like to submit a patch, send it to openssl-bugs@openssl.org with the string "[PATCH]" in the subject. Please be sure to include a textual explanation of what your patch does. If you are unsure as to whether a feature will be useful for the general OpenSSL community please discuss it on the openssl-dev mailing list first. Someone may be already working on the same thing or there may be a good reason as to why that feature isn't implemented. Patches should be as up to date as possible, preferably relative to the - current Git or the last snapshot. They should follow the coding style of - OpenSSL and compile without warnings. Some of the core team developer targets - can be used for testing purposes, (debug-steve64, debug-geoff etc). OpenSSL - compiles on many varied platforms: try to ensure you only use portable - features. + current Git or the last snapshot.

That kind of versioning works a bit differently between * operating systems. The most usual scheme is to set a major and a minor * number, and have the runtime loader check that the major number is equal * to what it was at application link time, while the minor number has to * be greater or equal to what it was at application link time. With this * scheme, the version number is usually part of the file name, like this: * * libcrypto.so.0.9 * * Some unixen also make a softlink with the major verson number only: * * libcrypto.so.0 * * On Tru64 and IRIX 6.x it works a little bit differently. There, the * shared library version is stored in the file, and is actually a series * of versions, separated by colons. The rightmost version present in the * library when linking an application is stored in the application to be * matched at run time. When the application is run, a check is done to * see if the library version stored in the application matches any of the * versions in the version string of the library itself. * This version string can be constructed in any way, depending on what * kind of matching is desired. However, to implement the same scheme as * the one used in the other unixen, all compatible versions, from lowest * to highest, should be part of the string. Consecutive builds would * give the following versions strings: * * 3.0 * 3.0:3.1 * 3.0:3.1:3.2 * 4.0 * 4.0:4.1 * * Notice how version 4 is completely incompatible with version, and * therefore give the breach you can see. * * There may be other schemes as well that I haven't yet discovered. * * So, here's the way it works here: first of all, the library version * number doesn't need at all to match the overall OpenSSL version. * However, it's nice and more understandable if it actually does. * The current library version is stored in the macro SHLIB_VERSION_NUMBER, * which is just a piece of text in the format "M.m.e" (Major, minor, edit). * For the sake of Tru64, IRIX, and any other OS that behaves in similar ways, * we need to keep a history of version numbers, which is done in the * macro SHLIB_VERSION_HISTORY.

The B structure is the same as the B type defined in RFC2459 (and elsewhere) and used for example in certificate subject and issuer names. X509_NAME_get_index_by_NID() and X509_NAME_get_index_by_OBJ() retrieve the next index matching B or B after B. B should initially be set to -1. If there are no more entries -1 is returned. +If B is invalid (doesn't correspond to a valid OID) then -2 is returned. X509_NAME_entry_count() returns the total number of entries in B. X509_NAME_get_entry() retrieves the B from B corresponding to index B. Acceptable values for B run from 0 to (X509_NAME_entry_count(name) - 1). The value returned is an internal pointer which must not be freed. X509_NAME_get_text_by_NID(), X509_NAME_get_text_by_OBJ() retrieve the "text" from the first entry in B which matches B or B, if no such entry exists -1 is returned. At most B bytes will be written and the text written to B will be null terminated. The length of the output string written is returned excluding the terminating null. If B is then the amount of space needed in B (excluding the final null) is returned. =head1 NOTES X509_NAME_get_text_by_NID() and X509_NAME_get_text_by_OBJ() are legacy functions which have various limitations which make them of minimal use in practice. They can only find the first matching entry and will copy the contents of the field verbatim: this can be highly confusing if the target is a muticharacter string type like a BMPString or a UTF8String. For a more general solution X509_NAME_get_index_by_NID() or X509_NAME_get_index_by_OBJ() should be used followed by X509_NAME_get_entry() on any matching indices and then the various B utility functions on the result. +Applications which could pass invalid NIDs to X509_NAME_get_index_by_NID() +should check for the return value of -2. Alternatively the NID validity +can be determined first by checking OBJ_nid2obj(nid) is not NULL. + =head1 EXAMPLES Process all entries: int i; X509_NAME_ENTRY *e; for (i = 0; i < X509_NAME_entry_count(nm); i++) { e = X509_NAME_get_entry(nm, i); /* Do something with e */ } Process all commonName entries: int loc; X509_NAME_ENTRY *e; loc = -1; for (;;) { lastpos = X509_NAME_get_index_by_NID(nm, NID_commonName, lastpos); if (lastpos == -1) break; e = X509_NAME_get_entry(nm, lastpos); /* Do something with e */ } =head1 RETURN VALUES X509_NAME_get_index_by_NID() and X509_NAME_get_index_by_OBJ() return the index of the next matching entry or -1 if not found. +X509_NAME_get_index_by_NID() can also return -2 if the supplied +NID is invalid.

This package contains the the OpenSSL cryptography and SSL/TLS extra documentation and POD files from which the man pages were produced. %prep %setup -q %build %define CONFIG_FLAGS -DSSL_ALLOW_ADH --prefix=/usr --openssldir=%{openssldir} perl util/perlpath.pl /usr/bin/perl %ifarch i386 i486 i586 i686 ./Configure %{CONFIG_FLAGS} linux-elf shared %endif %ifarch ppc ./Configure %{CONFIG_FLAGS} linux-ppc shared %endif %ifarch alpha ./Configure %{CONFIG_FLAGS} linux-alpha shared %endif %ifarch x86_64 ./Configure %{CONFIG_FLAGS} linux-x86_64 shared %endif LD_LIBRARY_PATH=`pwd` make LD_LIBRARY_PATH=`pwd` make rehash LD_LIBRARY_PATH=`pwd` make test %install rm -rf $RPM_BUILD_ROOT make MANDIR=/usr/man MANSUFFIX=ssl INSTALL_PREFIX="$RPM_BUILD_ROOT" install # Make backwards-compatibility symlink to ssleay ln -sf /usr/bin/openssl $RPM_BUILD_ROOT/usr/bin/ssleay %clean rm -rf $RPM_BUILD_ROOT %files %defattr(0644,root,root,0755) %doc CHANGES CHANGES.SSLeay LICENSE NEWS README %attr(0755,root,root) /usr/bin/* %attr(0755,root,root) /usr/lib/*.so* %attr(0755,root,root) %{openssldir}/misc/* %attr(0644,root,root) /usr/man/man[157]/* %config %attr(0644,root,root) %{openssldir}/openssl.cnf %dir %attr(0755,root,root) %{openssldir}/certs %dir %attr(0755,root,root) %{openssldir}/misc %dir %attr(0750,root,root) %{openssldir}/private %files devel %defattr(0644,root,root,0755) %doc CHANGES CHANGES.SSLeay LICENSE NEWS README %attr(0644,root,root) /usr/lib/*.a %attr(0644,root,root) /usr/lib/pkgconfig/openssl.pc %attr(0644,root,root) /usr/include/openssl/* %attr(0644,root,root) /usr/man/man[3]/* %files doc %defattr(0644,root,root,0755) %doc CHANGES CHANGES.SSLeay LICENSE NEWS README %doc doc %post ldconfig %postun ldconfig %changelog * Sun Jun 6 2005 Richard Levitte - Remove the incorrect installation of '%{openssldir}/lib'. * Wed May 7 2003 Richard Levitte - Add /usr/lib/pkgconfig/openssl.pc to the development section. * Thu Mar 22 2001 Richard Levitte - Removed redundant subsection that re-installed libcrypto.a and libssl.a as well. Also remove RSAref stuff completely, since it's not needed any more. * Thu Mar 15 2001 Jeremiah Johnson - Removed redundant subsection that re-installed libcrypto.so.0.9.6 and libssl.so.0.9.6. As well as the subsection that created symlinks for these. make install handles all this. * Sat Oct 21 2000 Horms - Make sure symlinks are created by using -f flag to ln. Otherwise some .so libraries are copied rather than linked in the resulting binary RPM. This causes the package to be larger than neccessary and makes ldconfig complain. * Fri Oct 13 2000 Horms - Make defattr is set for files in all packages so packages built as non-root will still be installed with files owned by root. * Thu Sep 14 2000 Richard Levitte - Changed to adapt to the new (supported) way of making shared libraries - Installs all static libraries, not just libRSAglue.a - Extra documents now end up in a separate document package * Sun Feb 27 2000 Damien Miller - Merged patches to spec - Updated to 0.9.5beta2 (now with manpages) * Sat Feb 5 2000 Michal Jaegermann - added 'linux-alpha' to configuration - fixed nasty absolute links * Tue Jan 25 2000 Bennett Todd - Added -DSSL_ALLOW_ADH, bumped Release to 4 * Thu Oct 14 1999 Damien Miller - Set default permissions - Removed documentation from devel sub-package * Thu Sep 30 1999 Damien Miller - Added "make test" stage - GPG signed * Tue Sep 10 1999 Damien Miller - Updated to version 0.9.4 * Tue May 25 1999 Damien Miller - Updated to version 0.9.3 - Added attributes for all files - Paramatised openssl directory * Sat Mar 20 1999 Carlo M. Arenas Belon - Added "official" bnrec patch and taking other out - making a link from ssleay to openssl binary - putting all changelog together on SPEC file * Fri Mar 5 1999 Henri Gomez - Added bnrec patch * Tue Dec 29 1998 Jonathan Ruano - minimum spec and patches changes for openssl - modified for openssl sources * Sat Aug 8 1998 Khimenko Victor - shared library creating process honours $RPM_OPT_FLAGS - shared libarry supports threads (as well as static library) * Wed Jul 22 1998 Khimenko Victor - building of shared library completely reworked * Tue Jul 21 1998 Khimenko Victor - RPM is BuildRoot'ed * Tue Feb 10 1998 Khimenko Victor - all stuff is moved out of /usr/local Index: vendor-crypto/openssl/dist-0.9.8/ssl/ssl_sess.c =================================================================== --- vendor-crypto/openssl/dist-0.9.8/ssl/ssl_sess.c (revision 291710) +++ vendor-crypto/openssl/dist-0.9.8/ssl/ssl_sess.c (revision 291711) @@ -1,989 +1,989 @@ /* ssl/ssl_sess.c */ /* Copyright (C) 1995-1998 Eric Young (eay@cryptsoft.com) * All rights reserved. * * This package is an SSL implementation written * by Eric Young (eay@cryptsoft.com). * The implementation was written so as to conform with Netscapes SSL. * * This library is free for commercial and non-commercial use as long as * the following conditions are aheared to.
