Some VIA processors come with an integrated crypto engine
(so called VIA PadLock ACE, Advanced Cryptography Engine)
that provides instructions for very fast cryptographic
operations with supported algorithms.
The instructions are used only when the CPU supports them.
Otherwise software encryption is used.
Selecting M for this option will compile a helper module
padlock.ko that should autoload all below configured
algorithms. Don't worry if your hardware does not support
some or all of them. In such case padlock.ko will
simply write a single line into the kernel log informing
about its failure but everything will keep working fine.
If you are unsure, say M. The compiled module will be
called padlock.ko
config CRYPTO_DEV_PADLOCK_AES
tristate "PadLock driver for AES algorithm"
depends on CRYPTO_DEV_PADLOCK
select CRYPTO_BLKCIPHER
Use VIA PadLock for AES algorithm.
Available in VIA C3 and newer CPUs.
If unsure say M. The compiled module will be
called padlock-aes.ko
config CRYPTO_DEV_PADLOCK_SHA
tristate "PadLock driver for SHA1 and SHA256 algorithms"
select CRYPTO_SHA1
select CRYPTO_SHA256
Use VIA PadLock for SHA1/SHA256 algorithms.
Available in VIA C7 and newer processors.
called padlock-sha.ko
