La máquina Enigma era un mecanismo de cifrado rotativo utilizado tanto para cifrado como para descifrado, ampliamente utilizada de varios modos en Europa desde los tempranos años 1920 en adelante. Su fama se la debe a haber sido adoptada por muchas fuerzas militares de Alemania desde 1930 en adelante. Su facilidad de manejo y su supuesta inviolabilidad fueron las principales razones para su amplio uso. Su cifrado, fue roto, y la lectura de la información que ofrecía en los mensajes que no protegió es a veces reconocida como la causa para acabar al menos un año antes la Segunda Guerra Mundial de lo que hubiera podido ser de otro modo.

In the history of
cryptography, the Enigma was a portable cipher machine used to encrypt and
decrypt secret messages. More precisely, Enigma was a family of related
electro-mechanical rotor machines
comprising a variety of different models.
The Enigma was
used commercially from the early 1920s on, and was also adopted by the military
and governmental services of a number of nations most famously by Nazi Germany before and
during World War II.
The German
military model, the Wehrmacht Enigma, is the version most commonly discussed.
The machine has gained notoriety because Allied cryptologists were able to
decrypt a large number of messages that had been enciphered on the machine. The
intelligence gained through this source
codenamed ULTRA was a significant
aid to the Allied war effort. The exact influence of ULTRA is debated, but a
typical assessment is that the end of the European war was hastened by two
years because of the decryption of German ciphers.
Although the
Enigma cipher has cryptographic weaknesses, it was, in practice, only their
combination with other significant factors which allowed codebreakers to read
messages: mistakes by operators, procedural flaws, and the occasional captured
machine or codebook.
