.Sh NAME
|
|
.Nm padlock
|
|
.Nd "driver for the cryptographic functions and RNG in VIA C3, C7 and Eden processors"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device crypto"
|
|
.Cd "device padlock"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
padlock_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The C3 and Eden processor series from VIA include hardware acceleration for
|
|
AES.
|
|
The C7 series includes hardware acceleration for AES, SHA1, SHA256 and RSA.
|
|
All of the above processor series include a hardware random number generator.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver registers itself to accelerate AES operations and, if available, HMAC/SHA1
|
|
and HMAC/SHA256 for
|
|
.Xr crypto 4 .
|
|
It also registers itself to accelerate other HMAC algorithms, although
|
|
there is no hardware acceleration for those algorithms.
|
|
This is only needed so
|
|
.Nm
|
|
can work with
|
|
.Xr ipsec 4 .
|
|
.Pp
|
|
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 .

|
|
The
|
|
.Nm
|
|
driver with AES encryption support was written by
|
|
.An Jason Wright Aq jason@OpenBSD.org .
|
|
It was ported to
|
|
.Fx
|
|
and then extended to support SHA1 and SHA256
