Historians both during and after the War did not know just why American carriers showed up at just the right time and place in the Coral Sea or at Midway. While Secretary Stimson ended State Department funding and effectively closed down Yardley's Black Chamber, he did not stop American code breaking which is why as Secretary of War a decade later he was reading decoded Japanese diplomatic messagesand no longer complaining about gentamanly behavior. The Japanese after considerable consideration decided that the best way to take advantage of the war in Europe was to strike south and expand their Empire into Southeast Asia (late-1939). Magic gave American officials the ability to read Japanese diplomatic dispatches in near real time.
Unmasking the American Magic operation of course would have been a major intelligence coup. American code breakers in Washington late-Decmber 6 began intercepting a 14-part Japanese diplomatic message. Much more important was the Japanese Navy's code which American cryptologists called JN-25.
It was an enciphered code, producing five numeral groups iwhich was what was actually broadcasted.
The principal defense of the Japanese Marus (merchant ships) was the immense size of the Pacific ocean. American code breakers after cracking the diplomatic Purple Code primarily focused on the JN-25 naval codes. After Pearl Harbor, the American code breaking effort steadily expabnded, but very little of that expanded effort was directed at the Japanese Army codes.
Cracking Japanese codes not only brought vital information about Japan, but also NAZI Germany.
The United States along with Finland and the Axis countries cracked some of the Soviet World war II codes.

As a result, Americans had little expertise with cryptology when Congress declared war (April 1917). For example, if you are in France and you want to call United States you must first enter France IDD code then United States dialing code. It was a cipher machine, but less complicatted than what the Germans were using and like the Germans, the Japanese were convinved that the system could not be cracked. It was not until months after Pearl Harbor that the cryptologists at Pearl (Station Hypo) and the Britih in Ceylon began breaking into JN-25. Army's top-secret Signal Intelligence Service (SIS), the forerunner of the National Security Agency (NSA), began working on Soviet secret messages (February 1943) hoping to crack the dioplomatic code. He went with the American Expeditionary Force (AEF) to France as a staff officer, but commanders there sought him out for advice on cryptographic issues. Navy had previously established a Code and Signal Section within the Office of Naval Intelligence (1924).
One outcome of the War was a $100,000 slush fund controlled by the Director of Naval Intelligence and kept secret from Congress. After the War, a small amount was used to fund break-ins at the Japanese Consulte in New York City. Many were fromm the Soviet Trade Office working with Lend Lease, but there were messages from any other agencies as well, including the military and intelligemce services. From an early stage, the SIS staff determined that the messages came from five different agencies with separate encryption systems.


Although the effort began during the War, the SIS dis not suceed in reading many of the messages until after the War. The Purple machine was a successor to earlier machines used to read Japanese diplomatic mesages.
Many of the messages the United States had to work with were messages associated with the Soviet Trade Office involved with Lend Lease. Richard Hallock, an Army Signal Corps lieutenant and trained an archaeologist (who worked with ancient writing systems) suceeded in developing insights into the system being used by Soviet trade officials who were relatively lax in their security measures (October 1943). Knowing nothing about codes, he decided on his own that a good beginning point would be to have a lose look at foreign codes.
This was a more difficult undertaking because the NKVD more carefully protected their messages, using double encryption. Together they would work out the additive system, but the Japanese complicated their wotk by updating the Red Code and additives. 168.] The location of the Magic operation in Washington meant that information from the decrypts were not sent to Pearl Harbor unless the War Department decided to send some of the intelligence obtained. And Yardley after Secretary Simson discovered decoded messages found himself without a job and broke. The Purple machine was a successor to earlier machines used to read Japanese diplomsatic mesages. He then not only sold code breaking details to the Japanese, but then published a book on it (1931). The British joined the effort and sent two of their cryptologists to Arlington Hall (1948). Thus American officials were provide an insight into Japanese plans, albeit not military operations. As information on Soviet espionage emerged, the Venona group contacted the Federal Bureau of Investigation (FBI). Simmering tensions in the Pacific caused the Navy to devote increading resources on codebreaking.
And as the Army had cracked the Japanese diplomatic Purle code (Magic), some Navy personnel were used to work on Purple messages, reducung the effort on JN-25.
By chance Rochefort commanding the Navy code unit at Pearl which would become known as Station Hypo.
319-25.] Soon the Americans were reading Army messages as soon s the Japanese (Match 1944).
