Amazon.com Review
People love secrets. Ever since the first word was written, humans have sent coded messages to each other. In The Code Book, Simon Singh, author of the bestselling Fermat's Enigma, offers a peek into the world of cryptography and codes, from ancient texts through computer encryption. Singh's compelling history is woven through with stories of how codes and ciphers have played a vital role in warfare, politics, and royal intrigue. The major theme of The Code Book is what Singh calls "the ongoing evolutionary battle between codemakers and codebreakers," never more clear than in the chapters devoted to World War II. Cryptography came of age during that conflict, as secret communications became critical to both sides' success.

Confronted with the prospect of defeat, the Allied cryptanalysts had worked night and day to penetrate German ciphers. It would appear that fear was the main driving force, and that adversity is one of the foundations of successful codebreaking.

In the information age, the fear that drives cryptographic improvements is both capitalistic and libertarian--corporations need encryption to ensure that their secrets don't fall into the hands of competitors and regulators, and ordinary people need encryption to keep their everyday communications private in a free society. Similarly, the battles for greater decryption power come from said competitors and governments wary of insurrection.

The Code Book is an excellent primer for those wishing to understand how the human need for privacy has manifested itself through cryptography. Singh's accessible style and clear explanations of complex algorithms cut through the arcane mathematical details without oversimplifying. --Therese Littleton

From Publishers Weekly
In an enthralling tour de force of popular explication, Singh, author of the bestselling Fermat's Enigma, explores the impact of cryptographyAthe creation and cracking of coded messagesAon history and society. Some of his examples are familiar, notably the Allies' decryption of the Nazis' Enigma machine during WWII; less well-known is the crucial role of Queen Elizabeth's code breakers in deciphering Mary, Queen of Scots' incriminating missives to her fellow conspirators plotting to assassinate Elizabeth, which led to Mary's beheading in 1587. Singh celebrates a group of unsung heroes of WWII, the Navajo "code talkers," Native American Marine radio operators who, using a coded version of their native language, played a vital role in defeating the Japanese in the Pacific. He also elucidates the intimate links between codes or ciphers and the development of the telegraph, radio, computers and the Internet. As he ranges from Julius Caesar's secret military writing to coded diplomatic messages in feuding Renaissance Italy city-states, from the decipherment of the Rosetta Stone to the ingenuity of modern security experts battling cyber-criminals and cyber-terrorists, Singh clarifies the techniques and tricks of code makers and code breakers alike. He lightens the sometimes technical load with photos, political cartoons, charts, code grids and reproductions of historic documents. He closes with a fascinating look at cryptanalysts' planned and futuristic tools, including the "one-time pad," a seemingly unbreakable form of encryption. In Singh's expert hands, cryptography decodes as an awe-inspiring and mind-expanding story of scientific breakthrough and high drama. Agent, Patrick Walsh. (Oct.) FYI: The book includes a "Cipher Challenge," offering a $15,000 reward to the first person to crack that code.

5.0 out of 5 stars Neatly illustrates the impact of encryption on history, November 2, 1999
By Jason Massey (Indianapolis, Indiana USA) - See all my reviews
Before Singh's "Code Book" came on the scene, the only other book I knew about is Kahn's "Codebreakers". I don't have the time to read such a large text as Kahn's book, so I was very pleased when this book became available.

Singh has done a very nice job of demonstrating how deep an impact cryptography has on history. He opens the book by recounting Mary Queen of Scots' conspiracy to have Queen Elizabeth murdered and how she attempted to use encryption to cloak her intentions. It was a very exciting way to open the book.

Singh has found the right combination of technical detail, historical detail, and character development.

Singh's explanation of how the German WWII Enigma functioned is exceptional. He made it very easy (and fun) to understand.

Singh's last chapter is also very neat on the subject of quantum cryptography. Though I have a BS in computer science, I'm no physics genius and Singh did a nice job of making (what I consider) difficult physics concepts easy to understand and of showing how they can be applied to modern cryptography.

Although I don't know a thing about "Fermat's last theorem", I've been so pleased with Singh's writing style that I'm considering reading that book also just to see what it is all about.

If you like codes/ciphers and want to read about their impact on history without reading a thousand pages then get this book. You'll be happy you did.

5.0 out of 5 stars A great read and a little more than just codes, December 12, 1999
Mr. Singh traces the history of cryptography from its recorded inception in roman times up through current applications. While all of the chapters held my interest it was Mr. Singh's work in chapters 4 through 6 that I feel deserve particular note.

Chapter 4 deals with the war effort at Bletchley Park and the work on the Engima machine. Here Mr.Singh adds an additional dimension by providing some insight into the work of Alan Turning, the development of Colossus, the first (now reported) electronic programmable computer and the unrecognized cryptanalysts who broke Ultra and the other codes of WWII. Chapter 6 brings us up to present day cryptographic issues from RSA and PGP to philosophical issues of personal privacy in modern society with web centric commerce and online book reviews. At each step in the process Singh successfully combines the elements of a technical treatise with a human values and features. For those wanting to go a little further under the hood and look at the processes and algorithms in some of the codes mentioned in the text, several appendices at the end of the book should fill that yearning. I found the book informative and enjoyable to read.

5.0 out of 5 stars Compelling material wrapped in interesting stories, March 29, 2000
By Douglas Welzel (Seattle, WA) - See all my reviews
(REAL NAME)   
It took me a while to finding to the time to read this because I was expecting a rather dry book on cryptography. The subject was somewhat interesting to me, but I didn't feel like plodding through a long book on the subject.

Once I started reading I realized The Code Book was totally different. Singh takes you on a tour of the history of cryptography through the history of the world. You will find that cryptography was an unexpected key element in several historical events.

Through the entire history, Singh's writing is exceptionally clear and easy to follow. The material in the book is accessible to all levels of reader -- even those with no knowledge of cryptography.
