	  Use Intel AES-NI instructions for AES algorithm.

	  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
494 495 496 497
	  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.
