.Dd June 5, 2006 .Dt PADLOCK 4 i386 .Os .Sh NAME .Nm padlock .Nd "driver for the cryptographic functions and RNG in VIA C3 and Eden processors" .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device crypto" .Cd "device padlock" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent padlock_load="YES" .Ed .Sh DESCRIPTION The C3 and Eden processor series from VIA include hardware acceleration for AES, as well as a hardware random number generator.
p The .Nm driver registers itself to accelerate AES operations for .Xr crypto 4 . It also registers itself to accelerate various HMAC algorithms, but there is no hardware acceleration for those algorithms, this is only needed, so .Nm can work with .Xr fast_ipsec 4 .
p The hardware random number generator supplies data for the kernel .Xr random 4 subsystem. .Sh HISTORY The .Nm driver first appeared in .Ox . The first .Fx release to include it was .Fx 6.0 . .Sh SEE ALSO .Xr crypt 3 , .Xr crypto 4 , .Xr intro 4 , .Xr random 4 , .Xr crypto 9 .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Jason Wright Aq jason@OpenBSD.org . It was ported to .Fx by .An Pawel Jakub Dawidek Aq pjd@FreeBSD.org . This manual page was written by .An Christian Brueffer Aq brueffer@FreeBSD.org .
