 442           RIPEMD-160 should be used.

 456           (not to be confused with RIPEMD-128).

1192           the TEA algorithm to address a potential key weakness
1193           in the TEA algorithm.
1194
1195           Xtendend Encryption Tiny Algorithm is a mis-implementation
1196           of the XTEA algorithm for compatibility purposes.
