 419           SEED cipher algorithm (RFC4269).
 420
 421           SEED is a 128-bit symmetric key block cipher that has been
 422           developed by KISA (Korea Information Security Agency) as a
 423           national standard encryption algorithm of the Republic of Korea.
 424           It is a 16 round block cipher with the key size of 128 bit.

 436           This is the Deflate algorithm (RFC1951), specified for use in
 437           IPSec with the IPCOMP protocol (RFC3173, RFC2394).
 438
 439           You will most probably want this if using IPSec.

 445           Michael MIC is used for message integrity protection in TKIP
 446           (IEEE 802.11i). This algorithm is required for TKIP, but it
 447           should not be used for other purposes because of the weakness
 448           of the algorithm.

 467           Camellia is a symmetric key block cipher developed jointly
 468           at NTT and Mitsubishi Electric Corporation.
