Adrian Bunkb6d44342008-07-16 19:28:00 +0800363 RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
364 to be used as a secure replacement for the 128-bit hash functions
365 MD4, MD5 and it's predecessor RIPEMD
366 (not to be confused with RIPEMD-128).

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

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

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