The book concludes with a discussion of " Pretty Good Privacy" (PGP), quantum computing, and quantum cryptography. Some of this material is based on interviews with participants, including persons who worked in secret at GCHQ.
Later sections cover the development of public-key cryptography. The Code Book covers diverse historical topics including the Man in the Iron Mask, Arabic cryptography, Charles Babbage, the mechanisation of cryptography, the Enigma machine, and the decryption of Linear B and other ancient writing systems. Thus the book's title should not be misconstrued as suggesting that the book deals only with codes, and not with ciphers or that the book is in fact a codebook. The Code Book describes some illustrative highlights in the history of cryptography, drawn from both of its principal branches, codes and ciphers.
The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography is a book by Simon Singh, published in 1999 by Fourth Estate and Doubleday.
