Synopsis :

A tour through history’s real codes and ciphers written by two of today’s best cipher crackers.

Expert codebreakers Elonka Dunin and Klaus Schmeh introduce you to the world of breaking encrypted texts, whether by hand or using the many free computer tools available today. Each chapter introduces you to a specific cryptographic technique and presents many real-life examples of text encrypted using that scheme, from modern postcards to nineteenth-century newspaper ads, war-time telegrams, notes smuggled into prisons, and even entire encrypted books. 

You'll learn how to:
  •  Crack simple substitution ciphers, polyalphabetic ciphers, transposition ciphers, dictionary codes, and more
  •  Use free online cryptanalysis software, like CrypTool 2, to aid your analysis
  •  Identify clues and patterns to figure out what encryption scheme is being used

Codebreaking is the perfect handbook for anyone hoping to break some piece of encrypted text, solve previously undiscovered secrets, or hide their own secret messages.

À propos de l?auteur: Elonka Dunin is an experienced crypto expert and maintains a list of the world's most famous unsolved codes on her elonka.com website. Bestselling author Dan Brown even named one of the characters in his Da Vinci Code sequel, The Lost Symbol, after her: “Nola Kaye” is a scrambled form of “Elonka." She is co-founder and co-leader of a group of cryptographers who are working hard to crack the final cipher on the famous Kryptos sculpture at CIA Headquarters, and in 2021 she was invited to give the TEDx talk "2,000 Years of Ordinary Secrets."

Klaus Schmeh is the most-published cryptology author in the world. He has written 15 books (in German) about the subject, as well as over 200 articles, 25 scientific papers, and 1,500 blog posts. He is a member of the editorial board of the scientific magazine, Cryptologia. Schmeh's main fields of interest are codebreaking and the history of encryption. His blog Cipherbrain is read by crypto enthusiasts all over the world. Schmeh is a popular speaker, known for his entertaining presentation style involving self-drawn cartoons and LEGO® models.
