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 34To compile this driver into the kernel, 35place the following lines in your 36kernel configuration file: 37.Bd -ragged -offset indent 38.Cd "device crypto" 39.Cd "device padlock" 40.Ed 41.Pp 42Alternatively, to load the driver as a 43module at boot time, place the following line in 44.Xr loader.conf 5 : 45.Bd -literal -offset indent 46padlock_load="YES" 47.Ed 48.Sh DESCRIPTION 49The C3 and Eden processor series from VIA include hardware acceleration for |
50AES. 51The C7 series includes hardware acceleration for AES, SHA 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 for 57.Xr crypto 4 . |
58It also registers itself to accelerate various HMAC algorithms, although 59there is no 60hardware 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. 69.Sh HISTORY 70The 71.Nm 72driver first appeared in 73.Ox . 74The first 75.Fx 76release to include it was 77.Fx 6.0 . 78.Sh SEE ALSO 79.Xr crypt 3 , 80.Xr crypto 4 , |
81.Xr fast_ipsec 4 , |
