It's funny to see how different the various people here have on the definition of "trivial". 10 years ago, I generated MD5 collisions in a few minutes with a tiny little executable I downloaded. That's what I call trivial.

If I had some DES-encrypted files that I'd lost the key to, and they were important enough that I needed their contents, I would probably be happy that I could crack the key today and recover them if I spent enough, but doing so would still not be "trivial".
