	  Khazad cipher algorithm.

	  Khazad was a finalist in the initial NESSIE competition.  It is
	  an algorithm optimized for 64-bit processors with good performance
	  on 32-bit processors.  Khazad uses an 128 bit key size.

	  Serpent cipher algorithm, by Anderson, Biham & Knudsen.

	  Keys are allowed to be from 0 to 256 bits in length, in steps
	  of 8 bits.  Also includes the 'Tnepres' algorithm, a reversed
	  variant of Serpent for compatibility with old kerneli code.

	  TEA cipher algorithm.

	  Tiny Encryption Algorithm is a simple cipher that uses
	  many rounds for security.  It is very fast and uses
	  little memory.

	  Xtendend Tiny Encryption Algorithm is a modification to
	  the TEA algorithm to address a potential key weakness
	  in the TEA algorithm.

	  Xtendend Encryption Tiny Algorithm is a mis-implementation 
	  of the XTEA algorithm for compatibility purposes.
