NAME
padlock
- driver for the cryptographic functions and RNG in VIA C3, C7 and Eden processors
SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device cryptodevice padlock
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
padlock_load="YES"
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.
The
driver registers itself to accelerate AES operations and, if available, HMAC/SHA1
and HMAC/SHA256 for
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
can work with
ipsec(4).
The hardware random number generator supplies data for the kernel
random(4)
subsystem.
The
driver first appeared in
Ox .
The first
Fx release to include it was
Fx 6.0 .
