  	  SEED cipher algorithm (RFC4269).

  	  SEED is a 128-bit symmetric key block cipher that has been
  	  developed by KISA (Korea Information Security Agency) as a
  	  national standard encryption algorithm of the Republic of Korea.
  	  It is a 16 round block cipher with the key size of 128 bit.

  	  in the TEA algorithm.
  
  	  Xtendend Encryption Tiny Algorithm is a mis-implementation
  	  of the XTEA algorithm for compatibility purposes.
