gnupg: Update to 2.2.18
- gpg: Changed the way keys are detected on a smartcards; this allows the use of non-OpenPGP cards. In the case of a not very likely regression the new option --use-only-openpgp-card is available. [#4681]
- gpg: The commands --full-gen-key and --quick-gen-key now allow direct key generation from supported cards. [#4681]
- gpg: Prepare against chosen-prefix SHA-1 collisions in key signatures. This change removes all SHA-1 based key signature newer than 2019-01-19 from the web-of-trust. Note that this includes all key signature created with dsa1024 keys. The new option --allow-weak-key-signatues can be used to override the new and safer behaviour. [#4755,CVE-2019-14855]
- gpg: Improve performance for import of large keyblocks. [#4592]
- gpg: Implement a keybox compression run. [#4644]
- gpg: Show warnings from dirmngr about redirect and certificate problems (details require --verbose as usual).
- gpg: Allow to pass the empty string for the passphrase if the '--passphase=' syntax is used. [#4633]
- gpg: Fix printing of the KDF object attributes.
- gpg: Avoid surprises with --locate-external-key and certain --auto-key-locate settings. [#4662]
- gpg: Improve selection of best matching key. [#4713]
- gpg: Delete key binding signature when deletring a subkey. [#4665,#4457]
- gpg: Fix a potential loss of key sigantures during import with self-sigs-only active. [#4628]
- gpg: Silence "marked as ultimately trusted" diagnostics if option --quiet is used. [#4634]
- gpg: Silence some diagnostics during in key listsing even with option --verbose. [#4627]
- gpg, gpgsm: Change parsing of agent's pkdecrypt results. [#4652]
- gpgsm: Support AES-256 keys.
- gpgsm: Fix a bug in triggering a keybox compression run if --faked-system-time is used.
- dirmngr: System CA certificates are no longer used for the SKS pool if GNUTLS instead of NTBTLS is used as TLS library. [#4594]
- dirmngr: On Windows detect usability of IPv4 and IPv6 interfaces to avoid long timeouts. [#4165]
- scd: Fix BWI value for APDU level transfers to make Gemalto Ezio Shield and Trustica Cryptoucan work. [#4654,#4566]
- wkd: gpg-wks-client --install-key now installs the required policy file.
