Daum and Lucks publishes real-world example of MD5 uselessness

Magnus Daum and Stefan Lucks publishes Attacking Hash Functions by Poisoned Messages, “The Story of Alice and her Boss”, which gives a meaningful explanation why being able to identify two messages that share the exact same MD5 hash in a reasonable amount of time renders MD5 no longer useful for providing message digests.

I just can’t help but laugh at what could have been a potential title and by-line for this article: Finding two PostScript documents with the same MD5, by Daum/Lucks. Juvenile — I know — but I still think it’s funny.
