This extremely rare unit 49was not very fast, lacked a RNG, and had a number of other bugs. 50.It Bluesteel 5601 51A faster and fixed version of the original, with a random number 52unit and large number engine added. 53.It Broadcom BCM5801 54A BCM5805 without public key engine or random number generator. 55.It Broadcom BCM5802 56A slower version of the BCM5805. 57.It Broadcom BCM5805 58Faster version of Bluesteel 5601. 59.It Broadcom BCM5820 6064 bit version of the chip, and significantly more advanced. 61.It Broadcom BCM5821 62Faster version of the BCM5820. 63.It Broadcom BCM5822 64Faster version of the BCM5820. 65.It Broadcom BCM5823 66A BCM5822 with AES capability. 67.It Broadcom BCM5825 68Faster version of the BCM5823. 69.El 70.Pp 71The 72.Nm 73driver registers itself to accelerate DES, Triple-DES, MD5-HMAC, 74and SHA1-HMAC operations for 75.Xr ipsec 4 76and 77.Xr crypto 4 . 78.Pp 79On those models which contain a public key engine (almost all of the 80more recent ones), this feature is registered with the 81.Xr crypto 4 82subsystem. 83.Pp 84On all models except the Bluesteel 5501 and Broadcom 5801, the driver 85registers itself to provide random data to the 86.Xr random 4 87subsystem. 88.Sh SEE ALSO 89.Xr crypt 3 , 90.Xr crypto 4 , 91.Xr intro 4 , 92.Xr ipsec 4 , 93.Xr random 4 , 94.Xr crypto 9 95.Sh HISTORY 96The 97.Nm 98device driver appeared in 99.Ox 2.8 . 100The 101.Nm 102device driver was imported to 103.Fx 104in 5.0. 105.Sh BUGS 106The BCM5801 and BCM5802 have not actually been tested. 107The AES capability of the BCM5823 is not yet supported; it is awaiting 108public disclosure of programming information from Broadcom. 109
