ubsec
driver supports cards containing any of the
following chips:
The ubsec
driver registers itself to
accelerate DES, Triple-DES, MD5, SHA1, MD5-HMAC, and SHA1-HMAC operations
for opencrypto(9), and
thus for ipsec(4) and
crypto(4). The driver also
supports acceleration of AES-CBC with the BCM5823 or newer.
On those models which contain a public key engine (almost all of the more recent ones), this feature is registered with the crypto(4) subsystem.
On all models except the Bluesteel 5501 and Broadcom 5801, the driver registers itself to provide random data to the rnd(4) subsystem.
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 subsequently imported to
NetBSD 2.0.
