MD5
acronymcryptography
Stands for: Message Digest 5
An old 128-bit hash function, cryptographically broken and unsafe for security use.
Message Digest 5 (RFC 1321) was once ubiquitous but is trivially collidable today. It survives only as a non-security checksum - for example in some legacy fingerprinting - and must never be used where collision resistance matters.
Also known as: md5
