| help |
| 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 |
