34.Dt UBSEC 4
35.Os
36.Sh NAME
37.Nm ubsec
38.Nd Broadcom and BlueSteel uBsec 5x0x crypto accelerator
39.Sh SYNOPSIS
40.Nm device ubsec
41.Sh DESCRIPTION
42The
43.Nm
44driver supports cards containing any of the following chips:
45.Bl -tag -width "Broadcom BCM5821" -offset indent
46.It Bluesteel 5501
47The original chipset, no longer made.  This extremely rare unit
48was not very fast, lacked a RNG, and had a number of other bugs.
49.It Bluesteel 5601
50A faster and fixed version of the original, with a random number
51unit and large number engine added.
52.It Broadcom BCM5801
53A BCM5805 without public key engine or random number generator.
54.It Broadcom BCM5802
55A slower version of the BCM5805.
56.It Broadcom BCM5805
57Faster version of Bluesteel 5601.
58.It Broadcom BCM5820
5964 bit version of the chip, and significantly more advanced.
60.It Broadcom BCM5821
61Faster version of the BCM5820.
62.It Broadcom BCM5822
63Faster version of the BCM5820.
64.El
65.Pp
66The
67.Nm
68driver registers itself to accelerate DES, Triple-DES, MD5-HMAC,
69and SHA1-HMAC operations for
70.Xr ipsec 4
71and
72.Xr crypto 4 .
73.Pp
74On those models which contain a public key engine (almost all of the
75more recent ones), this feature is registered with the
76.Xr crypto 4
77subsystem.
78.Pp
79On all models except the Bluesteel 5501 and Broadcom 5801, the driver
80registers itself to provide random data to the
81.Xr random 4
82subsystem.

90.Sh HISTORY
91The
92.Nm
93device driver appeared in
94OpenBSD 2.8.
95The
96.Nm
97device driver was imported to FreeBSD in 5.0.
98.Sh BUGS
99The BCM5801 and BCM5802 have not actually been tested.
