About MD2 hash algorithm
The MD2 Message-Digest Algorithm is a cryptographic hash function developed
by Ronald Rivest in 1989. The algorithm is optimized for 8-bit computers. MD2 is specified
in RFC 1319. Although MD2 is no longer considered secure, even as of 2014, it remains
in use in public key infrastructures as part of certificates generated with MD2 and RSA.
The "MD" in MD2 stands for "Message Digest".
Security problems
Rogier and Chauvaud (1997) described collisions of MD2's compression function, although
they were unable to extend the attack to the full MD2.
In 2004, MD2 was shown to be vulnerable to a preimage attack with time complexity equivalent
to 2104 applications of the compression function (Muller, 2004). The author concludes,
"MD2 can no longer be considered a secure one-way hash function".
In 2008, MD2 has further improvements on a preimage attack with time complexity of 273 compression
function evaluations and memory requirements of 273 message blocks.
In 2009, MD2 was shown to be vulnerable to a collision attack with time complexity of
263.3 compression function evaluations and memory requirements of 252 hash values. This is
slightly better than the birthday attack which is expected to take 265.5 compression function
evaluations.
In 2009, security updates were issued disabling MD2 in OpenSSL, GnuTLS, and Network Security Services.
