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-94
Description
An account of the resource
The M-94 was a cipher device based off the polyalphabetic manual substitution cipher. It was created by US Army major Joseph Mauborgne in 1917 with inspiration from a similar device invented by Thomas Jefferson in 1795. In 1921, it was introduced to the Army.
This device consisted of 25 circular discs- each with a different mixed alphabet of 26 letters. Although the security of the pocket device wasn't impressive, companies like Doehler, Reeve, and Alcoa had produced 9,432 of these tools by 1943 for use in the US Army.
The growing obsolete nature of this cipher device would inspire the need for the M-209.
