   6           This is the s390 hardware accelerated implementation of the
   7           SHA-1 secure hash standard (FIPS 180-1/DFIPS 180-2).

  14           This is the s390 hardware accelerated implementation of the
  15           SHA256 secure hash standard (DFIPS 180-2).
  16
  17           This version of SHA implements a 256 bit hash with 128 bits of
  18           security against collision attacks.

  26           This us the s390 hardware accelerated implementation of the
  27           DES cipher algorithm (FIPS 46-2), and Triple DES EDE (FIPS 46-3).

  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.

  51 config S390_PRNG

  54         default "m"
  55         help
  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.
