This is the s390 hardware accelerated implementation of the

- algorithm.
-
- Rijndael appears to be consistently a very good performer in
- both hardware and software across a wide range of computing
- environments regardless of its use in feedback or non-feedback
- modes. Its key setup time is excellent, and its key agility is
- good. Rijndael's very low memory requirements make it very well
- suited for restricted-space environments, in which it also
- demonstrates excellent performance. Rijndael's operations are
- among the easiest to defend against power and timing attacks.
