If you liked Dan Brown’s Da Vinci Code—or want to solve similarly baffling cyphers yourself—this is the book for you! A thrilling exploration of history’s most vexing codes and ciphers that uses hands-on exercises to teach you the most popular historical encryption schemes and techniques for breaking them. Solve history’s most hidden secrets alongside expert codebreakers Elonka Dunin and Klaus Schmeh, as they guide you through the world of encrypted texts. With a focus on cracking real-world document encryptions—including some crime-based coded mysteries that remain unsolved—you’ll be introduced to the free computer software that professional cryptographers use, helping you build your skills with state-of-the art tools. You’ll also be inspired by thrilling success stories, like how the first three parts of Kryptos were broken. Each chapter introduces you to a specific cryptanalysis technique, and presents factual examples of text encrypted using that scheme—from modern postcards to 19-century newspaper ads, war-time telegrams, notes smuggled into prisons, and even entire books written in code. Along the way, you’ll work on NSA-developed challenges, detect and break a Caesar cipher, crack an encrypted journal from the movie The Prestige, and much more. You’ll learn: How to crack simple substitution, polyalphabetic, and transposition ciphers How to use free online cryptanalysis software, like CrypTool 2, to aid your analysis How to identify clues and patterns to figure out what encryption scheme is being used How to encrypt your own emails and secret messages Codebreaking is the most up-to-date resource on cryptanalysis published since World War II—essential for modern forensic codebreakers, and designed to help amateurs unlock some of history’s greatest mysteries.

To break a code, you have to put yourself in the mind of your enemy in order to probe the strengths and weaknesses of their systems. It's a game of bluff and doublebluff. The Story of Codebreaking describes undercover operations, power struggles, secret alliances, and brilliant feats of teamwork. Those who invent codes and those who break them are remarkable, indefatigable characters. Find out how Mary Queen of Scots smuggled cryptic messages to her accomplices when she was plotting against her cousin Elizabeth I, or discover the methods used by codebreakers during World Wars I and II, most significantly those who cracked Enigma and intercepted Japanese naval messages prior to Pearl Harbor. The sheer doggedness of those who unraveled the Enigma code is thought to have shortened World War II by almost two years. Topics include: • Ancient ciphers and the art of encoding • Early spies, subterfuge and skytales • The making and breaking of Enigma • Japanese naval codes in World War II • Cold War cryptography

The magnificent, unrivaled 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 -- updated with a new chapter on computer cryptography and the Ultra secret. Man has created codes to keep secrets and has broken codes to learn those secrets since the time of the Pharaohs. 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, computers hacked. 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 to the Manhattan Project, codebreaking has shaped the course of human events to an extent beyond any easy reckoning. Once a government monopoly, cryptology today touches everybody. It secures the Internet, keeps e-mail private, maintains the integrity of cash machine transactions, and scrambles TV signals on unpaid-for channels. David Kahn's The Codebreakers takes the measure of what codes and codebreaking have meant in human history in a single comprehensive account, astonishing in its scope and enthralling in its execution. Hailed upon first publication as a book likely to become the definitive work of its kind, The Codebreakers has more than lived up to that prediction: it remains unsurpassed. With a brilliant new chapter that makes use of previously classified documents to bring the book thoroughly up to date, and to explore the myriad ways computer codes and their hackers are changing all of our lives, The Codebreakers is the skeleton key to a thousand thrilling true stories of intrigue, mystery, and adventure. It is a masterpiece of the historian's art.

Despite publicity given to the successes of British and American codebreakers during the Second World War, the study of signals intelligence is still complicated by governmental secrecy over even the most elderly peacetime sigint. This book, first published in 1986, lifts the veil on some of these historical secrets. Christopher Andrew and Keith Neilson cast new light on how Tsarist codebreakers penetrated British code and cypher systems. John Chapman’s study of German military codebreaking represents a major advance in our understanding of cryptanalysis during the Weimar Republic. The history of the Government Code and Cypher School – forerunner of today’s GCHQ – by its operational head, the late A.G. Denniston, provides both a general assessment of the achievements of British cryptanalysis between the wars and a tantalising glimpse of what historians may one day find in GCHQ’s forbidden archives. The distinguished cryptanalyst of Bletchley Park, the late Gordon Welchman, describes in detail how the Ultra programme defeated the German Enigma machine, while another Bletchley Park cryptographer, Christopher Morris, reminds us in his account of the valuable work on hand cyphers that wartime sigint consisted of much more than Ultra. Roger Austin’s study of surveillance under the Vichy regime shows the continuing importance of older and simpler methods of message interception such as letter-opening. Taken together, the articles establish sigint as an essential field of study for both the modern historian and the political scientist.

A fascinating exploration of the uncrackable codes and secret cyphers that helped win wars, spark revolutions and change the faces of nations. There have been secret codes since before the Old Testament, and there were secret codes in the Old Testament, too. Almost as soon as writing was invented, so too were the devious means to hide messages and keep them under the wraps of secrecy. In The Hidden History of Code Breaking, Sinclair McKay explores these uncrackable codes, secret ciphers, and hidden messages from across time to tell a new history of a secret world. From the temples of Ancient Greece to the court of Elizabeth I; from antique manuscripts whose codes might hold prophecies of doom to the modern realm of quantum mechanics, we will see how a few concealed words could help to win wars, spark revolutions and even change the faces of great nations. Here is the complete guide to the hidden world of codebreaking, with opportunities for you to see if you could have cracked some of the trickiest puzzles and lip-chewing codes ever created.
