In the history of cryptography, JADE was the codename given by US codebreakers to a Japanese cipher machine. The Imperial Japanese Navy used the machine for communications from late 1942 until 1944. JADE was similar to another cipher machine, CORAL, with the main difference that JADE was used to encipher messages in katakana using an alphabet of 50 symbols.
