SHA256 secure hash standard (DFIPS 180-2).
|

This version of SHA implements a 256 bit hash with 128 bits of
|

|
|
security against collision attacks.

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.

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