MD5 collisions

[pne]

Two PostScript files, both of which produce meaningful (but different) output and both of which hash to the same value using MD5: read the article and Bruce Schneier's brief commentary.

(The documents are a letter of recommendation and an order granting security clearance, but read the article first to understand the context.)

That's quite impressive. Wonder why it hasn't come up on bruce_schneier yet...
