 418           Khazad was a finalist in the initial NESSIE competition.  It is
 419           an algorithm optimized for 64-bit processors with good performance
 420           on 32-bit processors.  Khazad uses an 128 bit key size.

 430
 431           Anubis is a variable key length cipher which can use keys from
 432           128 bits to 320 bits in length.  It was evaluated as a entrant
 433           in the NESSIE competition.

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