  The legacy of Alan Turing - Computers & Technology (Other) - Helium - by Not Writing
Although similar in principle to the Enigma machine, the Lorenz cypher was vastly more complex, and it was not vulnerable to the techniques used to crack Enigma.
By this time, the Enigma cyphers were being cracked using a combination of human skill and the brute force searching of the mechanical "bombes" which has been designed for the specific task of decoding Enigma.
Unfortunately, the bombes were not flexible enough to cope with the subtleties of the Lorenz cypher so it had to be decoded by hand.

  Lorenz cypher
The Lorenz Schlüsselzusatz cipher machine was a World War II German teleprinter stream cipher.
While the Enigma machine was generally used by field units, Lorenz was used by headquarters units which could support the heavy machine, teletypewriter and attendant fixed circuits.
The Lorenz machine output groups of five pseudorandom bits to be XORed with the plaintext.

The cypher was in fact broken, and the reading of information in the messages it didn't protect is generally credited with ending World War II at least a year earlier than it would have otherwise.
Cypher users were told to not only use a different substitution for every letter, but also to use a very long key, so both of these techniques would fail (or at least be a lot harder).
The ultimate cypher of this kind would be one in which such a long key could be generated from a simple pattern, producing a cypher in which there are so many substitution alphabets that frequency counting and statistical attacks would be effectively impossible.

He was already showing his practical interest in making computing devices, bringing home from the States a small electronic multiplier he had made as part of an enciphering machine, and in Cambridge starting to build an analogue mechanical device to test the Riemann hypothesis.
He was in the first handful of the stream of able mathematicians drafted into their code-breaking operations.
These used a completely different mechanism and methodology from the Enigma machines, and correspondingly their codes were broken using a completely different mechanism and methodology.

 Bletchley Park, The Forge of Computer Creation « Off The Broiler
The German Navy (as well as the German army, the Wehrmacht) used an electromechanical device known as an ENIGMA machine to encode secret messages, which were then radioed via Morse code to the U-Boats on patrol.
The sheer complexity and numerical variation of the ENIGMA cyphers and the frequency of the changing of the wheel settings on the device basically made decoding by hand impossible.
This is a cypher masking tool used by the Polish research mathematicians.
