Sign in to saveAlso known as MD5 Message-Digest Algorithm, Message Digest Algorithm 5
The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, and was specified in 1992 as RFC 1321.
