NAME

     hifn -- Hifn 7751/7951/7811/7955/7956 crypto accelerator

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device crypto
	   device cryptodev
	   device hifn

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   hifn_load="YES"

DESCRIPTION

     The hifn driver supports various cards containing the Hifn 7751, 7951, 7811, 7955, and 7956 chipsets.

     The hifn driver registers itself to accelerate DES, Triple-DES, AES (7955 and 7956 only), ARC4, MD5, MD5-HMAC, SHA1, and SHA1-HMAC operations
     for ipsec(4) and crypto(4).

     The Hifn 7951, 7811, 7955, and 7956 will also supply data to the kernel random(4) subsystem.

HARDWARE

     The hifn driver supports various cards containing the Hifn 7751, 7951, 7811, 7955, and 7956 chipsets, such as:

	   Invertex AEON   No longer being made.  Came as 128KB SRAM model, or 2MB DRAM model.

	   Hifn 7751	   Reference board with 512KB SRAM.

	   PowerCrypt	   Comes with 512KB SRAM.

	   XL-Crypt	   Only board based on 7811 (which is faster than 7751 and has a random number generator).

	   NetSec 7751	   Supports the most IPsec sessions, with 1MB SRAM.

	   Soekris Engineering vpn1201 and vpn1211
			   See http://www.soekris.com/.  Contains a 7951 and supports symmetric and random number operations.

	   Soekris Engineering vpn1401 and vpn1411
			   See http://www.soekris.com/.  Contains a 7955 and supports symmetric and random number operations.

SEE ALSO

     crypt(3), crypto(4), intro(4), ipsec(4), random(4), crypto(9)

HISTORY

     The hifn device driver appeared in OpenBSD 2.7.  The hifn device driver was imported to FreeBSD 5.0.

CAVEATS

     The Hifn 9751 shares the same PCI ID.  This chip is basically a 7751, but with the cryptographic functions missing.  Instead, the 9751 is
     only capable of doing compression.  Since we do not currently attempt to use any of these chips to do compression, the 9751-based cards are
     not useful.

     Support for the 7955 and 7956 is incomplete; the asymmetric crypto facilities are to be added and the performance is suboptimal.

BUGS

     The 7751 chip starts out at initialization by only supporting compression.  A proprietary algorithm, which has been reverse engineered, is
     required to unlock the cryptographic functionality of the chip.  It is possible for vendors to make boards which have a lock ID not known to
     the driver, but all vendors currently just use the obvious ID which is 13 bytes of 0.

UBSEC(4)						   BSD Kernel Interfaces Manual 						  UBSEC(4)

NAME

     ubsec -- Broadcom and BlueSteel uBsec 5x0x crypto accelerator

SYNOPSIS

     ubsec* at pci? dev ? function ?

DESCRIPTION

     The ubsec driver supports cards containing any of the following chips:

	   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.

	   Bluesteel 5601    A faster and fixed version of the original, with a random number unit and large number engine added.

	   Broadcom BCM5801  A BCM5805 without public key engine or random number generator.

	   Broadcom BCM5802  A slower version of the BCM5805.

	   Broadcom BCM5805  Faster version of Bluesteel 5601.

	   Broadcom BCM5820  64 bit version of the chip, and significantly more advanced.

	   Broadcom BCM5821  Faster version of the BCM5820.  (This is the chip found on the Sun Crypto Accelerator 1000.)

	   Broadcom BCM5822  Faster version of the BCM5820.

	   Broadcom BCM5823  Faster version of the BCM5822.

	   Broadcom BCM5823  Faster version of the BCM5821, with AES hardware.

     The ubsec driver registers itself to accelerate DES, Triple-DES, MD5, SHA1, MD5-HMAC, and SHA1-HMAC operations for opencrypto(9), and thus
     for fast_ipsec(4) and crypto(4).

     On those models which contain a public key engine (almost all of the more recent ones), this feature is registered with the crypto(4) subsys-
     tem.

     On all models except the Bluesteel 5501 and Broadcom 5801, the driver registers itself to provide random data to the rnd(4) subsystem.

SEE ALSO

     crypto(4), fast_ipsec(4), intro(4), rnd(4), opencrypto(9)

HISTORY

     The ubsec device driver appeared in OpenBSD 2.8.  The ubsec device driver was imported to FreeBSD 5.0, back-ported to FreeBSD 4.8, and subse-
     quently imported to NetBSD 2.0.

BUGS

     The BCM5801 and BCM5802 have not actually been tested.

     Whilst some of the newer chips support AES, AES is not supported by the driver.
