Book Description
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.

Book Description
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

Book Description
A compelling story about tenacity and friendship, inspired by the real codebreaking women of Australia's top-secret Central Bureau in WWII. For readers who love Judy Nunn and Kate Quinn. They will dedicate their lives to their country, but no one will ever know... 1943, Brisbane: The war continues to devastate and the battle for the Pacific threatens Australian shores. For Ellie O'Sullivan, helping the war effort means utilising her engineering skills for Qantas as they evacuate civilians and deliver supplies to armed forces overseas. Her exceptional logic and integrity attract the attention of Central Bureau - an intelligence organisation working with England's Bletchley Park codebreakers. But joining Central Bureau means signing a lifetime secrecy contract. Breaking it is treason. With her country's freedom at risk, Ellie works with a group of elite women who enter a world of volatile secrets; deciphering enemy communications to change the course of the war. Working under immense pressure, they form a close bond - yet there could be a traitor in their midst. Can the women uncover the culprit before it's too late? As Ellie struggles with the magnitude of the promise she's made to her country, a wedge grows between her and those she holds dear. When the man she loves asks questions she's forbidden to answer, how will she prevent the double life she's leading from unravelling? PRAISE FOR THE CODEBREAKERS: 'An intriguing story of courage, friendship and resilience.' - Belinda Alexandra 'A unique and powerful historical war drama that highlights a fascinating group of women. Sinclair has produced a remarkable story that readers will find gripping and compelling.' - Canberra Weekly 'Sinclair has a magic touch with creating complex, layered characters and her scenarios test these characters completely.' - The Daily Telegraph

Book Description
WW2 Codebreaking People and Places is the first volume of a series on a glossary of codebreaking, ‘People and Places’, brings to the reader an easily understandable account and listing, of those involved in collecting and analysing military intelligence, principally during the second world war. while some will be well known, such as Alan Turing, many others have made significant contributions to codebreaking but fail to attract the attention of the media for the most part. From an individual named ‘Wren’ who worked at a codebreaking outstation supporting Bletchley Park, to a mathematician who modified a codebreaking machine just prior to D-Day, to a ladies foundationwear factory in Hertfordshire that helped make machine components, these people and places now can be appreciated as to where they fitted-in within the overall picture of gathering, and processing enemy intelligence in wartime. The entries are cross-referenced to enable the reader to research as much or as little as they want, to dip-in to the glossary, to use it as a basis for further study, or just to learn a little more about the people that helped us win the war with our allied friends. .
