 His paper (shortly to appear on the Cryptology ePrint

 where we've also made his software available (source code
 and a Win32 executable).

Thanks for interesting info!

btw, do you aware of another MD5 Collisions generating software
(requiring ~45 minutes per collision) available at
http://www.stachliu.com/collisions.html
I did not find any references to it in Marc's website/paper.

MD5 collisions in one minute

Hi all,

You might be interested in knowing that my MSc student
Marc Stevens has found a considerable speedup of MD5 
collision generation. His improvements of Wang's method
enables one to make MD5 collisions typically in one
minute on a PC; sometimes it takes a few minutes, and 
sometimes only a few seconds.
His paper (shortly to appear on the Cryptology ePrint

Grtz,
