X-WR-CALDESC:20 February 1939: The Japanese first use of the PURPLE machine
 -generated diplomatic cryptosystem. \n\nPURPLE was the codename Americans 
 gave an Imperial Japanese Navy diplomatic cipher used to send messages to

 re communicating over Purple. US and British cryptographers had already br

  the most important pieces of Magic US cryptographers 'found' was the 14-p
 art Japanese diplomatic message ominously breaking off relations with the 
 United States. That was at 1PM Washington time\, December 7\, 1941.\n\nLea
