Derek - As stated previously, we accept the challenge that you make - However, we do believe that it should be a two way street - If you are able to break the system, and everyone knows what we mean by break, then we will publicly admit that we are snake oil salesmen, and all the other things that Perry Metzger and others called us. We will go out of business, and tuck our tail and run. We will inform all major publications, WIRED, PC WEEK, PC Magazine, PC World, Infoworld and the like that our mundane system was cracked by the cypherpunks. Furthermore: you, they, will be free, to publish any material, any and all materials, will become the property of Cypherpunks if they break the system, inculding all of our source code - everything and they may do with it as they see fit. On the other hand: If the cypherpunks fail to break the system, they will acknowledge that, not that it is unbreakable, but that they tried to break the system and were unable to do so, Furthermore, they will so notify all the major publications, and news sources that they tried break the system and failed - not that it is unbreakable but simply that they could not break it. Further, that all materials supplied to Cypherpunks will be returned to us, and will not be published without our explicit written permission, unless the Cypherpunks later break the system. Further: That if you have not broken the system by August 1, 1996 the expiration date of the demo system to be provided to you, then we are free to advertise that Cypherpunks have been trying to break our system and have been unable to so to that date, Further the cypherpunks will publicly acknowledge same as indicated previously. You can still try to break the system and publish the results, and obtain all of our souce code, materials and whatsoever when you do. However, you must do so with a purchased system and not a free demo system. You can have infinity to try to break the system, but you cannot have that long to publicly admit that you have been unable to break it to date. I believe 5+ months is long enough to prove how easy it is to break, don't you. Further: If Cypherpunks are unable to break the system, then those who participated in the attempt will upbrade those cypherpunks, I at this stage prefer to call them cyphermouths, who have leaped before they looked, from a list supplied by us, based on received e-mail, in effect tell them to find out what they are talking about -before they start spouting off. Accordingly: We will not publish the algorithms on an Internet URL, for reasons that you, yourself, will soon come to understand. But we will provide it to a a very large selected set, you or your designee can do the selection, so long as all thosee selection are within the United States, of cypherpunks as follows: 1. We will provide a 12 user integrated demo system, each outfitted with 240 Nvelopes, and Nvelopeners, read OTPs. These will not be the 5600 bit systems, discusssed in the many e-mail messages that have been flowing back and forth, but will be our new 12288 bit systems, which we have been working on since yesterday, since everyone seemed to focus in on the 5600 bit OTPs - the algorithms themselves do not change, only parametric values, but it will take a couple of days to double check everything. These are in effect single user systems, but for your purposes, you may treat them as a site system. You may distribute them to any twelve sites in the United States - You may not knowingly deliver then into the hands of citizens of a country other than the United States, not even Canadians. Nor may you make copies of them and send them to anyone other than the 12 selected sites. Each of the sites may of course communicate back and forth using the system - be sure and don't include anything private because it is so easy to break. At each site, an unlimited number of people may work on cracking the system, without limitation, but they must agree to the terms set out herein in this offer. Such participants may travel to a site and work on it, but all work must be done at a site, not off premises, at home or whatever - the site may be operated 168 hours a week if desired, but no offsite work. After the 20 User pair Nvelopes are exhausted, the DEMO system will be set to recycle through the Nvelopes/Nvelopeners automatically, this means, as you might expect, that there is a finite chance, very remote but possible, that you may get one or more exact OTP repeats which means that you will be able to XOR out the OTP used, not the orginal but the one actually used - that doers not count as breaking the system, because it exists only as a convenience to continue testing the system without interruption. For production systems, this does not happen, cannot happen, unless you bugger your own, or allow someone else to,system. Also both performance and interface critisms are off limits during the five months, unless you break the system of course - by then you may crtique the performance, if you do it under lab conditions - a defragmented disk with at least 10 times data free, ie. compare apples to apples, not apples to oranges. We have been focusing on the OTP aspects of the system, to the detriment of performance and interface. For a first release though, we believe you will find them acceptable - we will have a full windows 95 interface and increased performance, hopefully by the time you break the system, within the next few months. 2. We will also supply 12 complete sets of the algorithms used, and orally clarify any questions or ambiguities that may arise. However, we will not submit to being unundated by a barrage of repetitious questions - no more than three cypherpunks may be appointed as questioners of IPG sales, and we are to be notified in writing, of who those appointees are. Inquiries from others will be directed to one those three. The algorithms must be worked on at sight, other than some innoculous trail and error processes and procedures which may be worked on at home - no publication of same until you break the system. Okay, enough badgering of each other - we deliberately did so yesterday, as some of you did, but now is the time for the cypherpunks, and for a few of what I will call cyphermouths, to put up or shut up. Assuming that you accept, we will supply any designee with the 12 sets, of materials, by UPS Next Day Air, and you may distrbute them as desired, subject to the above restrictions - we want to fight one problem at a time. I somehow hope that you are able to include my good friend, "joke for him I am sure but serious from me", Perry in one of the twelve sites, so he can show us how stupid we are. Two of the best computer system engineers that I have ever known had the last name Metzger, Bob and Charles, who was blind - anyway good luck Perry, you are going to need it. We await your reply - assuming you accept, we will deliver the materials, one of the first three days of next week.
