MD4, the Message-Digest Algorithm 4, is a cryptographic hash function designed by Ronald Rivest and introduced in 1990. It produces a 128-bit digest, normally written as a 32-digit hexadecimal number, and its design influenced later hash functions including MD5, SHA-1 and RIPEMD. The initialism MD stands for Message Digest. MD4 is now regarded as severely compromised: Den Boer and Bosselaers showed weaknesses in 1991, Hans Dobbertin found a full collision attack in 1995, later work made generating a collision as cheap as verifying one, and its preimage resistance was broken in 2008. RFC 6150 declared the original specification, RFC 1320, historic in 2011. Even so, a variant is used in the ed2k identifier scheme of the eDonkey2000 and eMule networks, rsync used it before version 3.0.0, and it is still used to compute NTLM password-derived key digests on Microsoft Windows.
