About MD2

MD2 (Message Digest 2) is a cryptographic hash function developed by Ronald Rivest in 1989. Although it is no longer considered secure for cryptographic purposes due to identified vulnerabilities, it remains important in the history of cryptography and is still used in some legacy systems.

MD2 processes messages in 16-byte blocks and produces a 128-bit (16-byte) hash value, typically represented as a 32-character hexadecimal string. The algorithm includes padding, checksum generation, and a complex transformation step to produce the final hash.
