An elementary introduction to the way the famous Enigma code used by the Germans during WWII. David Perry explains some of the history and the mathematics behind the code. This is part of an outreach program sponsored by NSF-VIGRE at UC Davis.
Polish motivation? Partitions of Poland 1772-1795 provided by Prussia and Russia was the end of Polish state. Polish Soviet war 1920... Soviet Russia has support of German communists. Before WWII it started again after Treaty of Rapallo (1922) Germans started tests his tanks in Soviet Russia. It wasn`t fear it was just politic realism.

@Channellock12
the best - and slower and complicated - was the One Time Pad.
The rotored Enigma was improved to become the Type X machine with 5 rotors and plug boards.
Then, the Rockex machines, one regular tape en clair but coded by a second tape.
Today they mostly use a sort of teletype with scramblers.

@Channellock12 I believe it was a machine called the M-209 and a lot of Navajo code talkers..

It's something a lot of teachers do.
Teachers at my university also mess around with their microphone/mic.clips all the time.
