National Security Agency Declassifies 200-Year-Old Book
John Cook · 06/09/11 11:40AMNot to be outdone by the National Archives, which is releasing a redacted version of the Pentagon Papers 40 years after they were actually published, the National Security Agency today declassified a book on cryptology that was published in 1809, during the presidency of James Madison. If it had been leaked before the NSA was ready, we totally would have lost the War of 1812.
