Download or read book Secrets of Making and Breaking Codes written by Hamilton Nickels and published by Skyhorse. This book was released on 2014-07-15 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since humans first began to communicate, we’ve had secrets to keep — secrets of state, war, business, or the heart. From the moment the first secret message was sent, others were busy trying to decipher it. By rearranging, substituting, or transposing symbols, any message can be encoded or decoded — if you know how. Secrets of Making and Breaking Codes is a practical field manual designed to teach you the basic mechanics of enciphering and deciphering communications. The author has used his extensive knowledge of and experience in electronic communications and languages — as well as his decades of fascination with secret codes — to demystify the field of cryptology. Hamilton Nickels uses plain, uncomplicated English and simple, workable systems that rely on neither advanced mathematics, nor on ethereal philosophies. This is the only hands-on guide to both the simplest cipher schemes — that need little more than scratch paper and a pencil to crack — as well as more sophisticated codes that use one-time code books, pocket calculators, and the most advanced computer-based systems used by the military and diplomatic corps of most governments. Letting the wrong eyes see a secret message can often make the difference between victory and defeat, success and failure, life and death. Secrets of Making and Breaking Codes will make mastering codes easier.

Available in PDF, EPUB and Kindle. Book excerpt: Learn how to program in Python while making and breaking ciphers—algorithms used to create and send secret messages! After a crash course in Python programming basics, you’ll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenère cipher. You’ll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure today’s online transactions, including digital signatures, email, and Bitcoin. Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, you’ll have learned how to code in Python and you’ll have the clever programs to prove it! You’ll also learn how to: - Combine loops, variables, and flow control statements into real working programs - Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish - Create test programs to make sure that your code encrypts and decrypts correctly - Code (and hack!) a working example of the affine cipher, which uses modular arithmetic to encrypt a message - Break ciphers with techniques such as brute-force and frequency analysis There’s no better way to learn to code than to play with real programs. Cracking Codes with Python makes the learning fun!

Book excerpt: The New York Times bestselling author of Dark Invasion and The Last Goodnight once again illuminates the lives of little-known individuals who played a significant role in America’s history as he chronicles the incredible true story of a critical, recently declassified counterintelligence mission and two remarkable agents whose story has been called "the greatest secret of the Cold War." In 1946, genius linguist and codebreaker Meredith Gardner discovered that the KGB was running an extensive network of strategically placed spies inside the United States, whose goal was to infiltrate American intelligence and steal the nation’s military and atomic secrets. Over the course of the next decade, he and young FBI supervisor Bob Lamphere worked together on Venona, a top-secret mission to uncover the Soviet agents and protect the Holy Grail of Cold War espionage—the atomic bomb. Opposites in nearly every way, Lamphere and Gardner relentlessly followed a trail of clues that helped them identify and take down these Soviet agents one by one, including Julius and Ethel Rosenberg. But at the center of this spy ring, seemingly beyond the American agents’ grasp, was the mysterious master spy who pulled the strings of the KGB’s extensive campaign, dubbed Operation Enormoz by Russian Intelligence headquarters. Lamphere and Gardner began to suspect that a mole buried deep in the American intelligence community was feeding Moscow Center information on Venona. They raced to unmask the traitor and prevent the Soviets from fulfilling Soviet Premier Nikita Khrushchev’s threat: "We shall bury you!" A breathtaking chapter of American history and a page-turning mystery that plays out against the tense, life-and-death gamesmanship of the Cold War, this twisting thriller begins at the end of World War II and leads all the way to the execution of the Rosenbergs—a result that haunted both Gardner and Lamphere to the end of their lives.
