Hi all, We announce: - an example of a target collision for MD5; this means: for two chosen messages m1 and m2 we have constructed appendages b1 and b2 to make the messages collide under MD5, i.e. MD5(m1||b1) = MD5(m2||b2); said differently: we can cause an MD5 collision for any pair of distinct IHVs; - an example of a pair of valid, unsuspicious X.509 certificates with distinct Distinguished Name fields, but identical CA signatures; this example makes use of the target collision.
See http://www.win.tue.nl/hashclash/TargetCollidingCertificates/, where the certificates and a more detailed announcement can be found.
