Ambiguity: MD2 is also the Quake_2 3D model format. This is used a lot in 3D circles. http://tfc.duke.free.fr/coding/md2-specs-en.html MD3 is the model format for Quake_3 etc 203.213.7.133 00:16, 19 March 2007 (UTC)

Citation needed?

As of January 2013, https access to www.facebook.com serves a certificate that is signed by a verisign class 3 certificate. The class 3 cert at the root of that chain it is self-signed using the MD2 hash function. Since this cert is self-signed, it doesn't provide anything in the way of security. However, if MD2 is ever broken with an arbitrary preimage attack, the signature on that root cert could be transferred to arbitrary certs. I'm not sure how to add a citation to wikipedia, however. (At least not to a fact, rather than to a paper in which someone claims the fact.) — Preceding unsigned comment added by 128.12.106.206 (talk) 02:04, 12 January 2013 (UTC)

As of Feb. 18th, 2013, the certificates on *.facebook.com and mail.google.com have chains with roots that are self-signed by SHA1, not MD2. I have removed the assertion. 128.111.8.104 (talk) 21:55, 18 February 2013 (UTC)

Year?

First published: 1992 But in the text someone wrote 1989 I think its 1989 because MD4 got published in 1990 and MD5 in 1991. And I dont think someone will make things with a high versionnumber and will decrease it later :) —Preceding unsigned comment added by 82.92.18.24 (talk) 21:38, 28 January 2008 (UTC)

As far as I can tell there's no contradiction: it was designed in 1989 and simply not published until 1992. -- intgr [talk] 06:57, 29 January 2008 (UTC)

RFC 1115 was published in 1989 and mentiones a Message-Digest-Algorithm called RSA-MD2 in Section 4.2. The referenced Source in this Section has a Notice "by Ronald L. Rivest 10/1/88" -- ThePacker (talk) 22:31, 29 August 2008 (UTC)
