'Riveting', MIKE GODWIN
'Approachable and compelling', GLEN MIRANKER
This practical guide to breaking codes and solving cryptograms by two world experts, Elonka Dunin and Klaus Schmeh, describes the most common encryption techniques along with methods to detect and break them. It fills a gap left by outdated or very basic-level books.
This guide also covers many unsolved messages. The Zodiac Killer sent four encrypted messages to the police. One was solved; the other three were not. Beatrix Potter's diary and the Voynich Manuscript were both encrypted - to date, only one of the two has been deciphered. The breaking of the so-called Zimmerman Telegram during the First World War changed the course of history. Several encrypted wartime military messages remain unsolved to this day. Tens of thousands of other encrypted messages, ranging from simple notes created by children to encrypted postcards and diaries in people's attics, are known to exist. Breaking these cryptograms fascinates people all over the world, and often gives people insight into the lives of their ancestors. Geocachers, computer gamers and puzzle fans also require codebreaking skills.
This is a book both for the growing number of enthusiasts obsessed with real-world mysteries, and also fans of more challenging puzzle books. Many people are obsessed with trying to solve famous crypto mysteries, including members of the Kryptos community (led by Elonka Dunin) trying to solve a decades-old cryptogram on a sculpture at the centre of CIA Headquarters; readers of the novels of Dan Brown as well as Elonka Dunin's The Mammoth Book of Secret Code Puzzles (UK)/The Mammoth Book of Secret Codes and Cryptograms (US); historians who regularly encounter encrypted documents; perplexed family members who discover an encrypted postcard or diary in an ancestor's effects; law-enforcement agents who are confronted by encrypted messages, which also happens more often than might be supposed; members of the American Cryptogram Association (ACA); geocachers (many caches involve a crypto puzzle); puzzle fans; and computer gamers (many games feature encryption puzzles).
The book's focus is very much on breaking pencil-and-paper, or manual, encryption methods. Its focus is also largely on historical encryption. Although manual encryption has lost much of its importance due to computer technology, many people are still interested in deciphering messages of this kind.

What could be more exciting, challenging, mysterious, and important in war than codebreaking? What could be a safer way to send a compromising message to your secret lover than to encrypt the message? If you already love spy stories and tales of business skulduggery in supposedly unbreakable ciphers, this is at last the single book that you must have. If you are not yet addicted to cryptography, this book will get you addicted. Read, enjoy, and test yourself on history's great still-unbroken messages! -- Jared Diamond is the Pulitzer Prize-winning author of Guns, Germs, and Steel; Collapse; and other international bestsellers
Riveting. Dunin and Schmeh show us that we each have our own inner codebreaker yearning to be set free. Codebreaking isn't just for super-geniuses with supercomputers, it's something we were all born to do. -- Mike Godwin, creator of Godwin's Law, former general counsel, Wikimedia Foundation
Codebreaking is a remarkable treatment of the art of decoding of hand-created codes. Clear and conversational in tone, it transforms a sometimes daunting topic into an approachable and compelling story. Its comprehensive survey of manual codes and techniques for cryptanalyzing them is thoroughly illustrated with real historical examples, from the Voynich Manuscript to the Zodiac Killer's encrypted messages. An excellent book for starting a deep-dive into cryptanalysis. -- Glen Miranker, former Chief Technology Officer, Apple Computers

This is the book we've all been waiting for, a page-turner packed with intrigue and mystery - the first practical book on codebreaking for the digital age. Code experts and enthusiasts Elonka Dunin and Klaus Schmeh patiently explain the basic types of codes and ciphers, and how to detect which scheme is being used. Say you discover an aged letter covered with mysterious symbols tucked into an old book in the attic. An encrypted communication from a long-dead relative, no doubt. But what does it say? Fear no more. With over a hundred cloak-and-dagger examples, ranging from the Emperor Ferdinand II, the Holy Roman Emperor from the House of Habsburg in the 1640s; to the Zodiac Killer in northern California in the 1960s, this is what you need. What a great way to introduce a new generation to the romance of mathematics! -- Scott Kim, who gave The Art of Puzzles TED talk, puzzle designer for Discover and Scientific American
Elonka and Klaus have created an incredible resource in this guidebook to codebreaking. In essence they found a code that needed breaking and solved it for us since a practical, up-to-date source like this did not yet exist. I cannot wait to use this book, not only to solve any cryptograms I might stumble across, but also to build new ones in my own works. An incredible, practical, up-to-date resource for codebreaking which has not existed up until now. -- Starr Long, former executive producer, Walt Disney Company

Cryptography? Ciphers? I thought this would be an easy book to put down.
I was very wrong.
Wow! A book that promises to break the code to codebreaking itself. For more than a decade, I led a team of experts trying to decipher the levels of meaning in the pop-culture works of Dan Brown. Through the publication of several such guidebooks, Elonka Dunin stood out as primus inter pares among our experts on codes. I am putting this book on gift lists for many occasions and for numerous people! -- Dan Burstein, author and editor of the New York Times-bestseller, Secrets of the Code

I have been a creator and solver of puzzles both virtual and physical my whole life, I even gave my wife a GPS-enabled puzzle box as a wedding present to lead her to our honeymoon. That being said, I could hardly imagine even approaching the problems Elonka Dunin and Klaus Schmeh have tackled. Fortunately for my ego, there remain a few even Elonka has not yet solved. However, if you wish to start down the rabbit hole, there is no better place to start than Codebreaking: A Practical Guide. I even hear that there are a few other hidden secrets embedded in this book! Good luck! -- Richard Garriott, computer gaming pioneer, 'Lord British' (Ultima Online)
I don't know if it's talent or genius . . . but these people are in a different world when it comes to good old logic and brains. It seems that codebreaking requires imagination, stamina and courage to follow its path to wherever it leads. Pure brilliance is barely enough to qualify for this gig. I could never decipher or encrypt anything in this category. I will never be solving cryptograms. But this book will take you on an amazing journey through an incredible maze. Darn exciting, I must say! -- David Lucas, award-winning composer, discoverer of Blue OEyster Cult, the cowbell guy!
Cryptography can seem like a daunting subject, but in this book Elonka and Klaus have made it understandable, approachable, and most of all: fun!

There is nothing quite like the satisfaction of applying the skills described in this book to unlock the mysterious secret messages. After reading this book you will be equipped with many tools to help you do it, too! -- Dave Oranchak founder of ZodiacKillerCiphers.com and host of Let's Crack Zodiac
Codebreaking: A Practical Guide is an extremely well-documented and enjoyable book written by Elonka Dunin and Klaus Schmeh. The book provides an overview of all classical ciphers and explains with exemplary clarity how to solve them. Entertaining examples are given at each stage and challenges are presented to the reader. A long time has passed since we last saw a book dealing with the solving classical ciphers. This book is a must have in any amateur cryptographer's library. The historical perspective of the book is also extremely important as essential background to the rich history of our field for new students who will later specialize in the more mathematical aspects of modern cryptology. An excellent book! -- David Naccache, Fellow, International Association for Cryptologic Research
