Adrian Bunkb6d44342008-07-16 19:28:00 +0800369 RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
370 to be used as a secure replacement for the 128-bit hash functions
371 MD4, MD5 and it's predecessor RIPEMD
372 (not to be confused with RIPEMD-128).

704
705 SEED is a 128-bit symmetric key block cipher that has been
706 developed by KISA (Korea Information Security Agency) as a
707 national standard encryption algorithm of the Republic of Korea.
708 It is a 16 round block cipher with the key size of 128 bit.
