It remains one message decrypted Enigma

1942. North Atlantic. German submarines were collected in "wolf packs" - organized groups of several dozen boats and reigned supreme in
Atlantic flushing Allied convoys. On the German submarines it was installed 4-rotor cipher machine "Enigma". With that, and conducted a successful coordination.
Breaking the dominance of "wolf packs" could crack the code "Enigma" and knowing the enemy's intentions to plan their own. What success has been made.

Enigma - rotary electric machine, which was used by the Germans during World War II. Usually five rotors create encryption with a certain amount of
million combinations (more rotors - more combinations). The Germans believed that such code is not open, as it requires an insane time on manual selection of options.
The British turned out smarter - in 1942, they made one of the world's first computer - "Colossus," which reveals the Enigma code in less than a day. As a result, they are always during the war, read the German encryption.

To reduce the number of options for sorting, the British hunted German submarines - they drowned in shallow water, with the help of divers were getting Enigma and sort out the design of the rotor (which letters and in what sequence they are applied) greatly facilitates the work of deciphering. Germans is used limited set of rotors, and too often they are changed. Naturally, all diving dive for German submarines were in the deepest secret from the Germans.
But as it turns out, there were 3 captured encryption, which did not manage to decipher.

Maybe for 3 intercepted messages not found a suitable set of rotors from the sinking of the submarine, and enthusiasts are now sorted out all the options?
After more than sixty years after the end of World War II, the project participants distributed computing M4 Message Breaking Project deciphered the message, encrypted using the machine Enigma.
 
Some time later, there was a project Enigma @ home http://enigmaathome.net , which is intended to decoding 2-remaining messages.
And so, in April 2013, it has been solved by another encryption.
You're one more crack. And it could be you. Verneuil your smartphone. You can do what could not be a whole army of cryptographers from Bletchley Park!

How, you ask?
Very simply, using distributed computing. This is when one big task is divided into many small tasks and distributed computers, smart phones on the network,connected to this project.
Projects there is a great of the set: this is mathematical, medical, on the subject of physics, space, astronomy, biology, climate and chemistry.
For every taste.
