└─>Support for VIA PadLock ACE
In linux kernel since version 2.6.12
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
