Huge noisy codebreaking machines called "bombes" were operated by Naval WRENs. By 1943, 3,000 messages per day were being intercepted and decoded.

England Part VI - Bletchley Park, Buckinghamshire
It was the most closely guarded secret of World War II.
Bletchley Park was the United Kingdom's main codebreaking establishment.
Over 10,000 people worked there, all sworn to absolute secrecy, and all remained silent about their work until the mid 1990s.
World War II enemy messages were produced in what seemed to be gibberish in five letter combinations generated by the German Enigma machine. Thousands of Enigma-coded messages were transmitted every day.
It's cipher had 150 million million million possible combinations which the Germans thought was unbreakable. I can't even imagine a number as large as that.
If you have some spare time and feel like building your own Enigma machine, this is how it worked.

There's lots more to the Enigma story than this, but the mind gets boggled by so much technology, well... mine does.
We spent a whole day here at Bletchley Park. Not only is the War Museum absolutely fascinating, the setting is in one of England's grand stately homes surrounded by well kept gardens.
Well worth a visit.
