| 8 | Some VIA processors come with an integrated crypto engine |
| 9 | (so called VIA PadLock ACE, Advanced Cryptography Engine) |
| 10 | that provides instructions for very fast {en,de}cryption |
| 11 | with some algorithms. |
| 12 | |
| 13 | The instructions are used only when the CPU supports them. |
| 14 | Otherwise software encryption is used. If you are unsure, |
| 15 | say Y. |

| 22 | Use VIA PadLock for AES algorithm. |
