A program to abuse the fact that random computer data isn't truly random. Takes a file and can convert it back and forth to random data(That is different each time). The only thing you have to distribute is the generated data, no key of any sort is needed. Ideal to run under pre-existing P2P applications for an extra layer of legal protection.
