After the war, the British destroyed nearly all evidence of their work. The Enigma secret remained classified until the 1970s. Consequently, Turing and his team never received public recognition in their lifetimes.

El funcionamiento era ingenioso: cada vez que se pulsaba una tecla, la corriente eléctrica pasaba por una serie de rotores que sustituían la letra original por otra. Lo que hacía que el código fuera "irrompible" era que los rotores giraban con cada pulsación, cambiando el patrón de cifrado constantemente. Con miles de millones de combinaciones posibles, un mensaje interceptado por los Aliados no era más que un galimatías sin sentido.

The Germans were confident. Their military mathematicians calculated that even if an enemy had a captured Enigma machine, they would have to test possible settings (15 followed by 22 zeros) to crack a single day’s code. while True: print("1

"The only thing we learned from Enigma is that we must never trust a machine to keep a secret." — Adapted from a Bletchley Park veteran.
