 830           Tiny Encryption Algorithm is a simple cipher that uses
 831           many rounds for security.  It is very fast and uses
 832           little memory.
 833
 834           Xtendend Tiny Encryption Algorithm is a modification to
 835           the TEA algorithm to address a potential key weakness
 836           in the TEA algorithm.
 837
 838           Xtendend Encryption Tiny Algorithm is a mis-implementation
 839           of the XTEA algorithm for compatibility purposes.
