Distributed Enigma Cryptanalysis
And you can help:
The M4 Project is an effort to break 3 original Enigma messages with the help of distributed computing. The signals were intercepted in the North Atlantic in 1942 and are believed to be unbroken.
EDITED TO ADD (3/8): One message has been broken.

I remember reading from applied crypto that enigma was broken. If that’s the case how’s there still unbroken messages lying around?
