It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. Once a government monopoly, cryptology today touches everybody. From the XYZ Affair to the Dreyfus Affair, from the Gallic War to the Persian Gulf, from Druidic runes and the kaballah to outer space, from the Zimmermann telegram to Enigma and to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. For 4,000 years, fierce battles have been waged between codemakers and codebreakers, and the story of these battles is civilization's secret history, the hidden account of how wars were won and lost, diplomatic intrigues foiled, business secrets stolen, governments ruined, and computers hacked.

Man has created codes to keep secrets and has broken codes to learn others' secrets since the time of the Pharaohs. This is the history of codes and ciphers-how they're made, how they're broken, and the many and fascinating roles they've played since the dawn of civilization in war, business, diplomacy, and espionage.
