If the current television series Station X about wartime codebreakers has whetted your appetite for the amazing story of Bletchley Park, read on. The country's greatest crossword buffs, mathematicians and code-crackers were employed to break Hitler's wartime communications codes and specifically, the supposedly secure Enigma machine. This website contains a huge array of details about Bletchley Park, including information on restoration work and an excellent description of how the Enigma machine worked (something that the TV programme skimped on). However, the best thing by far is the link to a pair of applets which simulate the Enigma machine, letting you encrypt and decrypt your own messages in exactly the same way as the German operators did. It seems odd to be using a powerful mainframe computer to simulate the action of a glorified typewriter, and might be a little easier to decode than some of the off-the-shelf computer encryption packages, but it's a fascinating insight into how cryptography has advanced in the last 50 years or so.

Also worth a look is www.wadham.ox.ac.uk/ahodges/book.html, a site which is dedicated to Alan Turing, the so-called father of modern-day computers and the creator of the machines that the codebreakers of Bletchley Park used to crack the German Enigma machine.
