NOVA Online Decoding Nazi Secrets Crack the Ciphers Crack the Ciphers by Jim Gillogly Here's your chance to crack ciphers similar to those Bletchley Park's codebreakers faced during World War II. Below, we present three ciphers of different levels of difficulty, from easiest to most challenging. Cryptanalyst Jim Gillogly created them using the Playfair, Double Playfair, and Double Transposition ciphers, respectively. In the opening paragraph for each challenge, we link to instructions regarding each cipher, which should help you along. The instructions link to hints, which in turn link to each cipher's solution.

Over a fortnight in November 1999, we offered a contest to see if anyone could crack any or all of the three ciphers. We deliberately made the contest short to give viewers a sense of urgency similar to that felt by the codebreakers of Bletchley Park. In the end, during those two weeks, no one succeeded in cracking Ciphers 2 and 3, and only four entrants managed to break Cipher 1. (See the to learn who the winners are, how they went about cracking the cipher, and what Jim Gillogly thought of their procedure.) We hope that the level of difficulty will only encourage you to try these challenging ciphers on your own time.

Tiltman, Bletchley Park This message was received by an intercept station in Scotland. Puzzle Questions For Interview With Answers Pdf there. The frequency and format indicate that it is a most urgent message from one of our agents who landed a week ago in Norway. His controllers have been unable to read it. Although it clearly uses his backup cipher, the, the keys assigned to him do not work.

We cannot reach him before his normal scheduled transmission in two weeks, so we urgently request that you attempt to decrypt this and let us know the contents. In case it helps, he is carrying materials to assist a previously dropped team in their work regarding the Norsk Hydro facility at Rjukan. His recognition code should appear in the message: It is 'beware ice weasels.'
