  18           Some VIA processors come with an integrated crypto engine
  19           (so called VIA PadLock ACE, Advanced Cryptography Engine)
  20           that provides instructions for very fast cryptographic
  21           operations with supported algorithms.
  22
  23           The instructions are used only when the CPU supports them.
  24           Otherwise software encryption is used.
