- driver for the cryptographic functions and RNG in VIA C3, C7 and Eden processors
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Cd device crypto
.Cd device padlock
Alternatively, to load the driver as a
module at boot time, place the following line in
The C3 and Eden processor series from VIA include hardware acceleration for
The C7 series includes hardware acceleration for AES, SHA1, SHA256 and RSA.
All of the above processor series include a hardware random number generator.
driver registers itself to accelerate AES operations and if available HMAC/SHA1
and HMAC/SHA256 for
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
The hardware random number generator supplies data for the kernel
