+        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.
