The MD5 hash function is a cryptographic hash function that produces a 128-bit hash value. It was developed by Ronald Rivest in 1991 as a successor to MD4. The MD5 algorithm is widely used for data integrity checks and digital signatures, but it is no longer considered secure for use in modern cryptographic applications due to its vulnerability to collision attacks. The MD5 hash function has been replaced by more secure hash functions such as SHA-2 and SHA-3.
Details about the specification can be found in IETF RFC 1321 https://datatracker.ietf.org/doc/html/rfc1321.
