My understanding was that MD4 had been broken once, at the cost of much computer time.
Not *that* much computer time... In my copy of Hans Dobbertin's paper, the abstract says ``An implementation of our attack allows to find collisions for MD4 in less than a minute on a PC.'' As far as I know, the difficulty of inverting MD4 is still an open problem -- but why would you want to use a broken algorithm like MD4 when you can use MD2, MD5, or SHA? - --- [This message has been signed by an auto-signing service.
