Different ball game. OTP isn't "unbreakable" . OTPs are secure because no matter what key you use, it _will_ decrypt, so your plaintext is still hidden simply because it could decrypt to whatever the person trying to decrypt it wants it to. Its not that its unbreakable, its that its breakable in _so many ways_. --Deviant PGP KeyID = E820F015 Fingerprint = 3D6AAB628E3DFAA9 F7D35736ABC56D39 Do, or do not; there is no try. -- Yoda -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQEVAwUBMphYvDCdEh3oIPAVAQGVWQf/UGedrHA9F0wqBBn0aUGNpP/0D2TOVTGm JBKhsCHoACMhowkHGMSEumnWQZ8mJ1pUAht306p2smVd+XWqRia1c73fwES+a/9X PEjaW3f6e8vsGnfQBlft0gEtaGzbwN9Dpbg01qxbpsLo9G0WqcrK8mHbOUISODjl uyRbVZXvpdL88pNMDsoc/4p1MhTY+2eYZvp/CSfQZNjn+mSnD8MVO/EyFSfWj5t2 oEiO1R+h0xN6KHPwv8jDybuelbs8voCHEDY5rDFGB5VKsI+9nqStPwUVb39S0Vec z5UPdrUUpfXP1aGxASYN9A88OLhzR00zCvtOPB/cp48FS6zC1PcH/A== =7Ik9 -----END PGP SIGNATURE-----

Shannon did, but Paul Bradley and friends(sic) proved that he/they could brute force OTPs, its on the record, so I guess Shannon was wrong, Nes pas? Someone as certain of his facts as PB cannot possibly be wrong, or did he say he was asleep - I guess so, he is obviously always asleep. I also can prove that our algorithm cannot be broken. All you have to do is to examine the algorithm and you will understand why it is unbreakable. That is a lot of chutzpah, but once you understand the algorithm and how simple it is to prove its unbreakability, then you will understand that our claim is absolutely correct. Unfortunately, many of you would rather beat your fingers on the keyboard about the abstract than find out the truth for yourself. It is really very simple.

More nonsense - unbreakable means that you cannot determine what the plaintext is. Shannon proved that you cannot prove what the plaintext is for OTPs, or for the system we have developed either. The fact that it could possibly be any plain text simply is another way of saying that it is unbreakable, they are one and the same thing. Like so many you are talking in circles and do not know what you are talking about or you would not waste your time on such nonsense - Paul Bradley even knows how to brute force OTPs, so you must be wrong there to.

That's precisely right - (almost all) cypherpunks have no idea what they're talking about. They use "kewl" words without understanding what they mean. The recent discussion of whether the (allegedly gay) droid Data used PGP or "fractal encryption" in some scifi movie is a good example. Some of these bullies, like Paul Bradley, realize that they don't know the meanings of the words they use. Paul Bradley not only posts nonsense about brute force attacks on OTP, but also harrasses anyone who exposes his utter ignorance, in en effort to intimidate them into shutting up. "Cypherpunks'" opinion of any proposed new cryptosystem is worthless and irrelevant. --- Dr.Dimitri Vulis KOTM Brighton Beach Boardwalk BBS, Forest Hills, N.Y.: +1-718-261-2013, 14.4Kbps
