30.Sh NAME

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
--- 7 unchanged lines hidden (view full) ---
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.
