German cryptologists used an Enigma machine to do this. Enigma used Symmetric Cryptography, meaning that the same key was used for both encryption and decryption. Each letter was sent through a series of circuits (consisting of a plug board and 3 rotating wheels) to create a highly randomized output.  The key is the Enigma set-up itself, which is the choice/order of the wheels, the ring setting and plug connections. Enigma configurations were changed daily. Every month, the Germans distributed a key sheet to Enigma operators. This contained a list of different configurations for each day of the month. This key sheet was critical to be able to decrypt the codes. As there were 159 million possible Enigma settings, the time taken to go through all the possible Enigma configurations to decrypt a…
