About RIPEMD-160
RIPEMD-160 (RACE Integrity Primitives Evaluation Message Digest) is a cryptographic hash function that produces a 160-bit (40-character) hash value. It was developed in Europe by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel as an alternative to SHA-1. RIPEMD-160 is particularly notable for its use in Bitcoin and other blockchain systems for generating addresses.
