CRYPTOLOGY

Fort Meade, Maryland - July 29, 2014: On display at the National Cryptologic Museum is the largest remaining piece of Baron Oshima Hiroshi's diplomatic Type B cipher machine. In 1945 it was recovered from the ruins of the Japanese Embassy in Berlin. Hiroshi was Imperial Japan's ambassador to Nazi Germany. The Type B cypher machines, codenamed "Purple" by the US cryptanalysts, used by diplomats differed from Japan's military.
