USA HISTORY

Detailed explanation-1: -The Purple machine was used by the Japanese in World War II to communicate with its most important embassies and consulates around the world, some of which were in Washington, Berlin and London. Purple was used to encrypt and thus conceal Japanese diplomatic information from the inquisitive eyes of foreign governments.

Detailed explanation-2: -Purple was a cipher used by Japan during World War Two to code diplomatic messages to various embassies throughout the world. The United States worked solely to untangle and decipher the super-enciphered signals they intercepted from the Japanese.

Detailed explanation-3: -The Purple cipher was used to send secretive messages overseas mostly to diplomats and military officials in Washington, Berlin, and London where Japan did not want unintended recipients snooping around. Breaking the Purple Machine was a daunting task for many reasons other than the complexity of the code itself.

Detailed explanation-4: -These diplomatic codes were transmitted on a machine, known to U.S. cryptographers as PURPLE. The PURPLE machine consisted of two electronic typewriters separated by a plugboard and a box that contained the encryption rotors. Similar to the Enigma machine, PURPLE would not encipher any letter to itself.

Detailed explanation-5: -A more powerful variant of the German Enigma Machine-an encryption method that the Allies were able to crack early in the war-the Purple Machine was a System-97 Alphabetical Typewriter that Japan created in 1937.
