 442           RIPEMD-160 should be used.

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

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

1203           Tiny Encryption Algorithm is a simple cipher that uses
1204           many rounds for security.  It is very fast and uses
1205           little memory.
1206
1207           Xtendend Tiny Encryption Algorithm is a modification to
1208           the TEA algorithm to address a potential key weakness
1209           in the TEA algorithm.
1210
1211           Xtendend Encryption Tiny Algorithm is a mis-implementation
1212           of the XTEA algorithm for compatibility purposes.
