  Enigma Machine
The Enigma machine was used by all branches of the German military as their main device for secure wireless communications until the end of World War 2.
In the age before digital electronics and computers, code breaking the ciphered messages produced by the Enigma machine was almost impossible even if the code breaker had a working copy of the Enigma machine, as long as he didn't know the right combination of initial electric and mechanical settings, which were also periodically changed.
The great efforts to code break the Enigma required the combined efforts and talents of brilliant mathematicians, code breakers, intelligence officers, and communications experts, deeply familiar with German language and mentality and with radio operator mentality and procedures.

  Bletchley Park - Wikipedia, the free encyclopedia
Codes and ciphers of several Axis countries were deciphered there, most famously the German Enigma.
Coded messages were taken down by hand and sent to Bletchley on paper or, later, by teleprinter.
Bletchley Park is mainly remembered for breaking messages encyphered on the German Enigma cypher machine, but its greatest cryptographic achievement may have been the breaking of the German "Fish" High Command teleprinter cyphers.

The actual enigma box itself used five points for letter swaps and for this reason you may see consecutive letters replacing repeated letters in the original message.
This code only uses three wheels in a set position and can be used to encode/decode a message as well as pass an encrypted string to it to figure out the initial position of the wheels used to encode the message.
Extrapolating, to decode a "true" Enigma message (with three of six wheels to choose from) the application would take about two minutes to run (which is a remarkable improvement over the original "engines" that would take six months on average to figure out the wheels and their initial positions from a message).

 Enigma and a way to its decryption
Much of the credit for breaking the code must be given to a group of accomplished Polish mathematicians, and the famous, and in the computer community well known mathematician Alan Turing.
Enigma was patented by Arthur Scherbius in 1918, an inventor who thought of it as a ciphering device for businesses that needed to communicate confidential documents.
When Poland was attacked by Germany, the heads of the code cracker team fled the country, and all their knowledge went to France and England.

As I understand the it, Enigma could only encrypt the twenty-six letters of the alphabet (which means all messages had to be in characters with no numbers, blanks or punctuation).
The reason why "Ultra" (which was the British code name for the decoding effort) was kept secret for so long seems to be motivated by protecting the governments of the time and avoid the embarrassment of having to explain why they allowed the Germans to bomb cities without taking measures to protect civilians.
The decoding of the "Enigma" messages by the English was accomplished by knowing parts of messages (such as the transmitting station's call letters) and trying every possible wheel and initial position to find those parts of the message that matched.

To break the code again Tom needs records of the codes sent from the submarines as they prepare to attack to get enough to break them -- they may have to let a convey be destroyed.

 Da Vinci judge's code an enigma | The World | The Australian
LONDON: The judge who presided over the Da Vinci Code trial has put a code of his own into his judgment and said yesterday he would "probably" confirm it to the person who broke it.
Judge Smith was arguably the highlight of the trial, with his acerbic questions and witty observations making the sometimes dry testimony more lively.
Mr Tench said the judge teasingly remarked that the code was a mixture of the italicised font code found in the book The Holy Blood and the Holy Grail - whose authors were suing Dan Brown's publisher, Random House, for copyright infringement - and the code found in Brown's The Da Vinci Code.

According to the organizers of M4, their open-source message-breaking application managed to crack one of the three messages early last week.
In breaking the first message, the project organizers used so-called brute force to test the encrypted message against all possible set-up configurations of the four-rotor Enigma.
However, this configuration did not include the machine's plugboard, which allowed the operator to swap two letters around before they were processed by the machine's rotors.
