RFC 1319: The MD2 Message-Digest Algorithm - RFC Editor

The MD4 Message-Digest Algorithm is a cryptographic hash function developed by Ronald Rivest in 1990. The digest length is 128 bits. The algorithm has influenced later designs, such as the MD5, SHA-1 and RIPEMD algorithms. The initialism "MD" stands for "Message Digest". The security of MD4 has been … Prikaži več Weaknesses in MD4 were demonstrated by Den Boer and Bosselaers in a paper published in 1991.
