The Code-Breakers: The Comprehensive History of Secret Communication from Ancient Times To The Internet (1996) By David Kahn
 
The Codebreakers – The Story of Secret Writing is a book by David Kahn, published in 1967, comprehensively chronicling the history of cryptography from ancient Egypt to the time of its writing. The United States government attempted to have the book altered before publication, and it succeeded in part.
 
The book finishes with a chapter on SETI. Because of the year of its publication, the book did not cover most of the history concerning the breaking of the German Enigma machine, which became public knowledge during the 1970s. Hence, not much was said of Alan Turing. It also did not cover the advent of strong cryptography in the public domain, beginning with the invention of public key cryptography and the specification of the Data Encryption Standard in the mid-1970s. The book was republished in 1996, and this new edition included an additional chapter briefly covering the events since the original publication.
