Simon Willison : Hash Collisions (The Poisoned Message Attack) - Hash Collisions (The Poisoned Message Attack). Demonstrates the MD5 weakness by providing two deliberately engineered PostScript documents with the same MD5 hash but radically different rendered output.
deusx : Hash Collisions (The Poisoned Message Attack) - "Collision resistance means that it is infeasible to find two different inputs M and M' with the same hash H(M)=H(M'). Note that many collisions exist, but it has to be infeasible to actually find even a single collision!"
