35	  This is the s390 hardware accelerated implementation of the
36	  AES cipher algorithms (FIPS-197). AES uses the Rijndael
37	  algorithm.
38
39	  Rijndael appears to be consistently a very good performer in
40	  both hardware and software across a wide range of computing
41	  environments regardless of its use in feedback or non-feedback
42	  modes. Its key setup time is excellent, and its key agility is
43	  good. Rijndael's very low memory requirements make it very well
44	  suited for restricted-space environments, in which it also
45	  demonstrates excellent performance. Rijndael's operations are
46	  among the easiest to defend against power and timing attacks.
47
48	  On s390 the System z9-109 currently only supports the key size
49	  of 128 bit.

56	  Select this option if you want to use the s390 pseudo random number
57	  generator. The PRNG is part of the cryptographic processor functions
58	  and uses triple-DES to generate secure random numbers like the
59	  ANSI X9.17 standard. The PRNG is usable via the char device
60	  /dev/prandom.
