[email protected] has recently been added to the Gridcoin whitelist and having raised the suggestion to add it I thought it would be a good idea to explain what it is working on. But first some background on the Enigma Machine for which I am going to refer to some experts on youtube:

So what is [email protected] working on?
In the words of the project homepage
“[email protected] is a wrapper between BOINC and Stefan Krah's M4 Project. '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.' "
Seems simple enough! But wait, the eagle eyed among you may have spotted that the three messages mentioned in that description have now already been broken.
Wait, What, They’ve already be cracked?
The first message was broken on February 20th, 2006 by [email protected]

The Second Message was broken on March 7th, 2006 by [email protected]

The third remaining message has been broken by Dan Girard. See: http://www.enigma.hoerenberg.com.
So, again, what is [email protected] working on now?
Well, now you know the background then you shouldn’t be surprised to hear that there is another unbroken message that needs breaking. The message in question is:
Unfortunately for this message the enigma “key” is not known although there are some clues as can be seen in the image and as are described in the above link. For this reason we need to try three different enigma “keys”.
This means that we could be working on this one for a while.
