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.
