MD2 Hash Generator
Generate an MD2 hash for a string of text. Enter the text to hash and produce the 32-character hexadecimal message digest.
What is MD2?
MD2 is a cryptographic hash function designed by Ronald Rivest for 8-bit computers and published by the IETF in RFC 1319. It produces a 128-bit message digest that is commonly written as 32 lowercase hexadecimal characters.
This tool hashes the text you enter as UTF-8 bytes and writes the resulting MD2 digest to the output box without sending the text to a server. It is useful for checking legacy MD2 test vectors, comparing old application output, or learning how historical message-digest algorithms format their results.
MD2 is obsolete for security-sensitive use. RFC 6149 moved MD2 to Historic status after published collision, preimage, and second-preimage attacks, so do not use MD2 for passwords, signatures, certificates, integrity protection, or new cryptographic designs. Prefer modern approved hash functions such as SHA-256 or SHA-3 for real security work.
