MD2 (hash function)

The MD2 Message-Digest Algorithm is a <a href="/facts/Cryptographic_hash_function/cuxkgbST">cryptographic hash function</a> developed by <a href="/facts/Ronald_Rivest/nQsIcAKa">Ronald Rivest</a> in 1989.[2] The algorithm is optimized for <a href="/facts/8-bit/2CkhLNoH">8-bit</a> computers. MD2 is specified in <a href="/facts/Request_for_Comments/esftTvE7">IETF RFC</a> 1319. The "MD" in MD2 stands for "Message Digest".
Even though MD2 is not yet fully compromised, the IETF retired MD2 to "historic" status in 2011, citing "signs of weakness". It is deprecated in favor of <a href="/facts/SHA-2/P59oPeGq">SHA-256</a> and other strong hashing algorithms.
Nevertheless, as of 2014<a href="https://en.wikipedia.org/w/index.php?title=MD2_(hash_function)&action=edit">[update]</a>, it remained in use in <a href="/facts/Public_key_infrastructure/7fwMLxF4">public key infrastructures</a> as part of <a href="/facts/Certificate_(cryptography)/J7aYI4Bx">certificates</a> generated with MD2 and <a href="/facts/RSA_(algorithm)/XTzyfHuq">RSA</a>.
