+ help
+ This is the s390 hardware accelerated implementation of the
+ AES cipher algorithms (FIPS-197). AES uses the Rijndael
+ 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.
+ On s390 the System z9-109 currently only supports the key size
+ of 128 bit.
