What really makes this encryption effective is that
like the real life machine, the wheels rotate either to
the left or right after each character. So the
relationship between each character shifts constantly.
As a result, even repeating characters such as
"AAAAAAAAAA" are represented with garbage such as
"BGPVLKHWCD".

It would be virtually impossible to look at the
encrypted characters and determine their relationship
to one another. There are so many possibilities and
combinations of the above criteria, it would have to be
solved through brute force. I am not a mathematician,
so if anyone can tell me the possible combinations, I
would appreciate it.

When the Germans used this machine, it baffled the
Allies, who frantically tried to break it with no
success. It wasn't until a German U-Boat was forced to
surface in a naval battle and was captured that the
Allies got a huge break. An Enigma machine was captured
along with a code book that showed the information
needed to decrypt the messages.

The U-Boat was scuttled and the crew was kept in a top
secret location. The U-Boat was simply considered lost
during battle and Germans continued the war not knowing
the truth.

When the war in the Atlantic turned for the worse, the
Germans, who believed their code to be unbreakable,
believed that there were spies in their top level
officials. They never considered that the code was
being decrypted through a captured machine, so as a
result, they set up elaborate networks to try and find
these "spies". Paranoia being what it was, many loyal
German officers were tortured and murdered for treason,
even though they had committed no such offense.
