43 kernel configuration file:
44 .Bd -ragged -offset indent
46 .Cd "device cryptodev"

59 driver supports cards containing Broadcom and BlueSteel uBsec 5x0x
60 crypto accelerator chips.
64 driver registers itself to accelerate DES, Triple-DES, MD5-HMAC,
65 and SHA1-HMAC operations for

85 The original chipset, no longer made.
86 This extremely rare unit
87 was not very fast, lacked a RNG, and had a number of other bugs.
89 A faster and fixed version of the original, with a random number

92 A BCM5805 without public key engine or random number generator.
94 A slower version of the BCM5805.
96 Faster version of Bluesteel 5601.
98 64 bit version of the chip, and significantly more advanced.
