What code did they break at Bletchley Park?

Enigma
Enigma and the Bombe The main focus of Turing’s work at Bletchley was in cracking the ‘Enigma’ code. The Enigma was a type of enciphering machine used by the German armed forces to send messages securely.

Who solved the enigma code?

British mathematician Alan Turing, who helped crack Nazi Germany’s ‘Enigma’ code and laid the groundwork for modern computing, was pardoned on Tuesday, six decades after his conviction for homosexuality is said to have driven him to suicide.

How did codebreakers at Bletchley Park crack the Enigma code?

While there, Turing built a device known as the Bombe. This machine was able to use logic to decipher the encrypted messages produced by the Enigma. However, it was human understanding that enabled the real breakthroughs. The Bletchley Park team made educated guesses at certain words the message would contain.

Who broke the German Enigma code?

The Enigma code was first broken by the Poles, under the leadership of mathematician Marian Rejewski, in the early 1930s.

How did Turing’s machine work?

Turing’s attack was based on the use of ‘cribs’ (comparing patterns of the encrypted message and a known portion of plain text) to break the key. This approach was aided by the fact that no letter on the Enigma could be represented by itself in an enciphered message.

How long was the Enigma code kept secret?

Although the secret was kept for nearly 30 years after the end of WW2, it’s now nearly 50 years since the public was told that the Allies had broken literally millions of Enigma-encrypted messages during the war, providing a wealth of authentic Intelligence about German military plans, reactions, state of readiness.

Did Turing meet Churchill?

Churchill was introduced to Turing during a visit to Bletchley Park in September 1941 and the following month Turing and three other cryptographers wrote directly to Churchill asking for more administrative resources, a request which the Prime Minister immediately granted.

How long would it take to crack Enigma today?

A young man named Alan Turing designed a machine called a Bombe, judged by many to be the foundation of modern computing. What might take a mathematician years to complete by hand, took the Bombe just 15 hours. (Modern computers would be able to crack the code in several minutes).
