26.\" 27.Dd July 28, 2006 28.Dt PADLOCK 4 i386 29.Os 30.Sh NAME 31.Nm padlock 32.Nd "driver for the cryptographic functions and RNG in VIA C3, C7 and Eden processors" 33.Sh SYNOPSIS --- 14 unchanged lines hidden (view full) --- 48.Sh DESCRIPTION 49The C3 and Eden processor series from VIA include hardware acceleration for 50AES. 51The C7 series includes hardware acceleration for AES, SHA1, SHA256 and RSA. 52All of the above processor series include a hardware random number generator. 53.Pp 54The 55.Nm |
56driver registers itself to accelerate AES operations and, if available, HMAC/SHA1 |
57and HMAC/SHA256 for 58.Xr crypto 4 . 59It also registers itself to accelerate other HMAC algorithms, although 60there is no hardware acceleration for those algorithms. |
61This is only needed so |
62.Nm 63can work with 64.Xr fast_ipsec 4 . 65.Pp 66The hardware random number generator supplies data for the kernel 67.Xr random 4 68subsystem. |
