It took us five years to venture through the different systems cryptology offers to keep information private. Our suggestions, why we regard the One Time Pad as the only system that offers permanent perfect security and when we put them into the public domain, received responses which were mixed. Still, all comments and suggestions we received, helped on our journey and we are grateful and indebted to each and everybody offering criticism or encouragement.

Mentioning all of the people here is impossible (some of them are only known to us via their avatars and aliases), but a few deserve a special credit. The first one we would like to mention is Barry Shelton - Shelton | Winston & Strawn LLP, who took the time to look through our draft papers. Barry is not only an excellent patent lawyer, but also a qualified professional engineer and software developer with US patents to his name. He has published online articles on encryption and a book that introduces the reader into the mystery of cryptology. To see all his publications and his professional record click on the link we have provided in this paragraph.

One thing remaining to be mentioned is, that Barry did not check for grammatical, spelling or punctuation errors. These errors and mistakes are our own and if you encounter them and want them removed, please contact us. Here we are only left to say thank you, Barry, for your factual checks, the advice you gave and the time you have given to help us.

The next person we would like to mention is Professor James H. Hamlyn-Harris (Jim), Deputy Head, Computer Science and Software Engineering, Faculty of Information & Communication Technologies, Swinburne University of Technology, Australia. Jim wrote an article for TheConversation, which permitted comments from readers of the online magazine. We participated in the comments, which at a later stage became a private email exchange. We supplied all our data and ideas and Jim took the time to evaluate them. His comment made public in the discussion to the article: "I'm not complaining. It's very good. I can't see any weaknesses." Thanks for that Jim, because it decided for us, that we would go ahead with our project. Without your assessment, we might have dropped it there and then.

The third person we want to mention is Anthony Scott Thompson. Tony, as he likes to be called, is President/Founder of Introspective Networks, with an impressive background in the IT field. Tony holds US patents and the company he created is well established. We first did meet Tony on a website, where he defended the use of the OTP, which was about five years ago. Since then we have exchanged ideas, argued about definitions (entropy, randomness etc) and concluded that mathematical algorithms in cryptology don't provide security but only add obscurity for the end user. Tony's approach to the OTP differs from our approach, since it still requires two transmissions and additional hardware. His ideas are just tested by the US Air Force research labs and we know that he will succeed in proving his inventions.

Here again we would like to say thanks for the time you spent and the arguments, ideas and suggestions you made, Tony. You have helped us to shape our website, so that people without deep knowledge in mathematics or electronic engineering could understand what we tried to achieve.
