The following tables compare general and technical information for a number of cryptographic hash functions. Please see the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date.


General information

Basic general information about the cryptographic hash functions: year, designer, references, etc. The column "Year" refers to the first official description of the algorithm, not designed date.

MD2 1989 Ronald Rivest RFC 1319
MD4 1990 Ronald Rivest RFC 1320
MD5 1992 Ronald Rivest MD4[1] RFC 1321
RIPEMD 1990 The RIPE Consortium[2]
RIPEMD-128/256 1996 Hans Dobbertin, Antoon Bosselaers, Bart Preneel RIPEMD[3] Website

SHA-0 1993 NSA SHA-0
SHA-1 1995 NSA SHA-0 FIPS 180--3
SHA-256/224 2002/2004 NSA FIPS 180--3
SHA-512/384 2002 NSA FIPS 180--3

Compression function

The following tables compare technical information for compresion functions of cryptographic hash functions. The information comes from the specifiations, please reference them for more details. All size counts bits, not bytes. And the omitted multiplicands are word sizes.
