Find a way to reverse the algorithm used to encrypt the password - for instance, if the passwords are encrypted ROT13, all you need do is a second ROT13 and you'll have the password.... If they're ecnrypted with a simple XOR, its harder... if they're hashed with MD5 it's (hopefully) mathematically impossible
/me racks brains... From memory, the PKZIP program used a fairly simple LFSR-based encrpyption, which is fairly easy to crack, but I don't know details off hand.. Other than that, the only decent solution I can think of is to use a quantum computer, which would try all possible passwords simultaneously, and then spit out to you only the correct answer....
