 452           RIPEMD-160 is a 160-bit cryptographic hash function. It is intended

 454           MD4, MD5 and it's predecessor RIPEMD
 455           (not to be confused with RIPEMD-128).

 812           ARC4 cipher algorithm.
 813
 814           ARC4 is a stream cipher using keys ranging from 8 bits to 2048
 815           bits in length.  This algorithm is required for driver-based
 816           WEP, but it should not be for other purposes because of the
 817           weakness of the algorithm.

1202           Tiny Encryption Algorithm is a simple cipher that uses
1203           many rounds for security.  It is very fast and uses
1204           little memory.
1205
1206           Xtendend Tiny Encryption Algorithm is a modification to
1207           the TEA algorithm to address a potential key weakness
1208           in the TEA algorithm.
1209
1210           Xtendend Encryption Tiny Algorithm is a mis-implementation
1211           of the XTEA algorithm for compatibility purposes.
