 420           Anubis cipher algorithm.
 421
 422           Anubis is a variable key length cipher which can use keys from
 423           128 bits to 320 bits in length.  It was evaluated as a entrant
 424           in the NESSIE competition.

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