Joseph, Well done! A good analysis, with some good points. I don't think I mentioned that minus byte at all. I have been thinking some more about this program, and although it uses an irreversible (generally) bit involving the multiply I was thinking that maybe the author had intended this (although I wonder if he saw this or not), and the intention was that the first string should somehow fix this up. hmm, I don't know. Even so, there should actually be many possible keys for each possible name in the keyfile. But like you say I wouldn't like to trace it back although it's easy enough with a zero first string and a calculator :) Cronos Cronos |
