The people were mainly in a few of the huts at Bletchley Park, just down the road from here. The British-built Enigma machines they deciphered the messages with were superior to the originals in that they printed onto sticky tape (like telegrams) rather than just illuminating lamps. Of course, typing the ciphertext into the Enigma machine is the easy bit - you have to work out the correct ground setting of the rotors that had been chosen, and the positions of the plugs in the superencipherment plugboard. That's what the cryptanalysts used the Polish-designed bombas for. All this has been public knowledge for twenty years. > [...] > I have the knowledge and will spread it whenever possible [...] > [...] > Do you doubt me :-) Yes, though I find the meaning of the smiley rather cryptic. But I have an open mind and would be interested to know what new cyrptanalytical methods you have discovered. -- David Wright, Open University, Earth Science Department, Milton Keynes MK7 6AA U.K. email: [EMAIL PROTECTED] tel: +44 1908 653 739 fax: +44 1908 655 151 -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
