From the time of the ancient pharaohs to the modern world of Internet banking, civilization has relied on codes and ciphers to keep its secrets. Emperors and queens, generals and politicians, the heads of giant corporations and humble lovers have all made use of the security encryption offers. Indeed, the 4,999-year history of cryptography has been a kind of arms race: each time a more complex encryption has been developed, it has been attacked, and, more often than not, defeated, leading to even tougher codes.

CODEBREAKER chronicles the fascinating story of codes -- from Julius Caesar and Mary Queen of Scots to quantum cryptography and the next generation -- and the historical events that have turned on them. But, however eye-opening are the inner workings of the Caesar shift cipher or the codes of the Navajo Windtalkers, even more intriguing is the allure of unsolved codes. CODEBREAKER profiles some of those hailed as unbreakable, such as the magnificent Dorabella and Beale Ciphers, and the Voynich manuscript. And, at the end, you're invited to solve several codes using the knowledge you've gained throughout the book.

Including profiles of cryptology and decryption experts and quantum cryptographers, and profusely illustrated with photographs, codes, and sidebars explaining the intricacies of cryptology, CODEBREAKER is an irresistible tour of an arcane and influential world.
