++    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.
