Abstract :
BLETCHLEY PARK´S role in the defeat of the Axis Powers in the Second World War has become legendary. This is where a team of cryptanalysts of the Government Code and Cypher School worked on the Enigma machine code as well the Lorenz ciphers (and some 150 other diplomatic cryptosystems). But it is the decoding of enemy Enigma communications generated by a primitive-looking machine, resembling a manual typewriter with rotating code wheels, and its link with Alan Turing, that keeps Bletchley in the public imagination to this day.
