-.Dt UBSEC 4
-.Os
-.Sh NAME
-.Nm ubsec
-.Nd Broadcom and BlueSteel uBsec 5x0x crypto accelerator
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following lines in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device crypto"
-.Cd "device cryptodev"
-.Cd "device ubsec"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-ubsec_load="YES"
-.Ed
-.Sh DEPRECATION NOTICE
-The
-.Nm
-driver is not present in
-.Fx 13.0
-and later.
-The majority of crypto algorithms supported by this driver are no longer
-used by the kernel in
-.Fx 13.0 .
-.Sh DESCRIPTION
-The
-.Nm
-driver supports cards containing Broadcom and BlueSteel uBsec 5x0x
-crypto accelerator chips.
-.Pp
-The
-.Nm
-driver registers itself to accelerate DES, Triple-DES, MD5-HMAC,
-and SHA1-HMAC operations for
-.Xr ipsec 4
-and
-.Xr crypto 4 .
-.Pp
-On those models which contain a public key engine (almost all of the
-more recent ones), this feature is registered with the
-.Xr crypto 4
-subsystem.
-.Pp
-On all models except the Bluesteel 5501 and Broadcom 5801, the driver
-registers itself to provide random data to the
-.Xr random 4
-subsystem.
-.Sh HARDWARE
-The
-.Nm
-driver supports cards containing any of the following chips:
-.Bl -tag -width "Broadcom BCM5822" -offset indent
-.It Bluesteel 5501
-The original chipset, no longer made.
-This extremely rare unit
-was not very fast, lacked an RNG, and had a number of other bugs.
-.It Bluesteel 5601
-A faster and fixed version of the original, with a random number
-unit and large number engine added.
-.It Broadcom BCM5801
-A BCM5805 without public key engine or random number generator.
-.It Broadcom BCM5802
-A slower version of the BCM5805.
-.It Broadcom BCM5805
-Faster version of Bluesteel 5601.
-.It Broadcom BCM5820
-64 bit version of the chip, and significantly more advanced.
-.It Broadcom BCM5821
-Faster version of the BCM5820.
-This is the chip found on the Sun Crypto Accelerator 1000.
-.It Broadcom BCM5822
-Faster version of the BCM5820.
-.It Broadcom BCM5823
-A BCM5822 with AES capability.
-.It Broadcom BCM5825
-Faster version of the BCM5823.
-.El
-.Sh SEE ALSO
-.Xr crypt 3 ,
-.Xr crypto 4 ,
-.Xr intro 4 ,
-.Xr ipsec 4 ,
-.Xr random 4 ,
-.Xr crypto 9
-.Sh HISTORY
-The
-.Nm
-device driver appeared in
-.Ox 2.8 .
-The
-.Nm
-device driver was imported to
-.Fx 5.0 .
-.Sh BUGS
-The BCM5801 and BCM5802 have not actually been tested.
-The AES capability of the BCM5823 is not yet supported; it is awaiting
-public disclosure of programming information from Broadcom.
