	  Some VIA processors come with an integrated crypto engine
	  (so called VIA PadLock ACE, Advanced Cryptography Engine)
	  that provides instructions for very fast cryptographic
	  operations with supported algorithms.
	  
	  The instructions are used only when the CPU supports them.
	  Otherwise software encryption is used.

	select CRYPTO_BLKCIPHER
	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.

	  /dev/prandom.
