To find the daily key, Rejewski build
6 replicas of the Enigma machine
and connected them.
The new machine could run through more than 17,000 indicator settings. He called this machine, ‘the bomb’.
The bomb was used to secretly read the traffic from the German Enigma machines for several years.

Germans added two new roters into the Enigma machine. This made it harder for the Poles to read the traffic
The Poles asked their allies, Britian and France to help them with the analysis and codebreaking of the German messages.

The British smuggle out the Enigma replica machines two weeks before Germany invaded Poland
The smuggled Enigma replicas were taken to the British code . and cypher school at Bletchley Park.
Alan Turing, a British mathematician at Bletchley Park thought of a different way of using the ‘bombs’ for testing the German codes.
