RIPEMD-160
RIPEMD-160 is another hash function; it computes a 160-bit message digest.
There is a RIPEMD-160 home page, with test vectors and pseudocode for RIPEMD-160. For padding the message, RIPEMD-160 acts like MD4 (RFC 1320).
Find the RIPEMD-160 message digest of a string of octets. Use the ASCII encoded string “Rosetta Code”. You may either call an RIPEMD-160 library, or implement RIPEMD-160 in your language.
