Cipher tools and machines
Description
An account of the resource
Cipher Tools and Machines contains examples of cipher tools and machines seen through out history, particularly within the context of military history. From Ancient Greece to the Cold War, cryptology has played a significant part in the communication and intelligence efforts between opposing forces.
They, along with cryptanalysts, have even been credited with shortening the duration of wars. Without the British intelligence project ULTRA, WWII may have lasted for another two years. However, while many great cryptanalysts hail from Britain, the UK is not exclusive in their cryptographic abilities. The Enigma was invented in Germany, and its stronger rendition, Fialka- in Russia. In comparison to these cryptomachines, the US SIGABA remains unbroken. Those are only a few cipher machines flound in this collection.

M-209
Description
An account of the resource
The M-209 was a cipher machine invented by Boris Hagelin or AB Cryptoteknik at the beginning of WWII. As a pin-and-lug cipher machine, it did not require electricity. During the war, German cryptanalysts called the machine "AM-1" for "American Machine #1".
In 1942, cryptanalysts from the US and UK had a debate over this machine. The British were concerned that the Italians would be able to read American Hagelin traffic, as they had been able to read Italian Hagelin traffic. However, the US chose to ignore this- citing that breaking the M-209 would be too difficult and time-consuming for the Axis powers. As it turned out, the Germans were able to read ~10% of American Hagelin traffic. This was 6% due to cryptanalysis and 4% due to captured keys. However, this decryption usually took 7-10 days- often rendering the message old and not useful.
