Hi! My friend has just written a new crypto program that he is trying to get included on a PC Magazine CD-ROM over here... I don't know too much about it at the moment, but he said he thought it would be a good idea to see if anyone on this list could crack it and thus help to make it more secure. I don't know too much about it ATM... I know it doesn't exercise key technology and relies on the secrecy of the algorithm (which from my very limited knowledge on cryptography I think makes it almost doomed from the start (?))... I have some ciphertext of this application but apart from that I have nothing else... Would anyone have any objectiosn to this being posted to the list? If not, could someone tell me what I should post to the list, plaintext and resulting ciphertext, would that be enough, or shoudl I post some info on the algorithms as well ??? The application is written in Visual Basic and I could probably get a copy of the compiled (well VB is actually interpreted, but that's neither here or there) .EXE file.... -- Karl Marx
