RIPEMD-160 (ISO/IEC 10118-3:2004).

RIPEMD-160 is a 160-bit cryptographic hash function. It is intended

to be used as a secure replacement for the 128-bit hash functions

MD4, MD5 and it's predecessor RIPEMD (not to be confused with RIPEMD-128).

It's speed is comparable to SHA1 and there are no known attacks against

RIPEMD-160.
