  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.

 119           This is the s390 hardware accelerated implementation of the
 120           AES cipher algorithms (FIPS-197). AES uses the Rijndael
 121           algorithm.
 122
 123           Rijndael appears to be consistently a very good performer in
 124           both hardware and software across a wide range of computing
 125           environments regardless of its use in feedback or non-feedback
 126           modes. Its key setup time is excellent, and its key agility is
 127           good. Rijndael's very low memory requirements make it very well
 128           suited for restricted-space environments, in which it also
 129           demonstrates excellent performance. Rijndael's operations are
 130           among the easiest to defend against power and timing attacks.
 131
 132           On s390 the System z9-109 currently only supports the key size
 133           of 128 bit.

 141           generator. The PRNG is part of the cryptographic processor functions

 143           ANSI X9.17 standard. The PRNG is usable via the char device
