  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.

 133          This is the s390 hardware accelerated implementation of the
 134          AES cipher algorithms (FIPS-197). AES uses the Rijndael
 135          algorithm.
 136
 137          Rijndael appears to be consistently a very good performer in
 138          both hardware and software across a wide range of computing
 139          environments regardless of its use in feedback or non-feedback
 140          modes. Its key setup time is excellent, and its key agility is
 141          good. Rijndael's very low memory requirements make it very well
 142          suited for restricted-space environments, in which it also
 143          demonstrates excellent performance. Rijndael's operations are
 144          among the easiest to defend against power and timing attacks.

 146          On s390 the System z9-109 currently only supports the key size
 147          of 128 bit.
