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

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

  48. help
  49. Select this option if you want to use the s390 pseudo random number
  50. generator. The PRNG is part of the cryptograhic processor functions
  51. and uses triple-DES to generate secure random numbers like the
  52. ANSI X9.17 standard. The PRNG is usable via the char device
  53. /dev/prandom.
