WebThe MD2 Message-Digest Algorithm is a cryptographic hash function developed by Ronald Rivest in 1989. [2] The algorithm is optimized for 8-bit computers. MD2 is specified in IETF RFC 1319. [3] The "MD" in MD2 stands for "Message Digest". WebCryptography is the study and practice of techniques for secure communication, allowing only the sender and intended recipient of a message to view its contents. Cryptography is closely related to encryption, the process of scrambling readable text such that it can only be read by people with a secret code, or decryption key.
