RIPEMD‑160, published in 1996, is a hash algorithm designed by Hans Dobbertin, Antoon Bosselaers, and Bart Preneel in an open academic community. The size of the output of RIPEMD‑160 is 160 bits. RIPEMD‑160 is a strengthened version of the RIPEMD hash algorithm that was developed in the framework of the European Union's project RIPE (RACE Integrity Primitives Evaluation), 1988‑1992. RIPEMD‑160 was adopted by the International Organization for Standardization (ISO) and the IEC in the ISO/IEC 10118‑3:2004 international standard [21].
