Code Breaking explores the fascinating history and strategic importance of deciphering secret communications, from ancient methods to modern cybersecurity. This interdisciplinary study reveals how cryptography and cryptanalysis have shaped military power and international relations. Did you know that code breaking existed long before computers? The book examines early methods of cryptography and cryptanalysis, providing context for understanding the quantum leaps made during and after World War II, including Allied efforts at Bletchley Park and the Enigma machine. The book progresses chronologically, starting with fundamental concepts and moving through key historical episodes like the Zimmerman Telegram and the breaking of Japanese codes during World War II. A significant portion is dedicated to modern cybersecurity, including encryption algorithms and network security protocols. By balancing technical explanations with historical accounts and strategic implications, Code Breaking offers a comprehensive understanding of this critical field.

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!

Code Breaking History explores the fascinating evolution of cryptography, from ancient ciphers to modern cybersecurity, revealing how code breaking has shaped pivotal moments in history. The book examines the intertwined development of cryptographic techniques, such as substitution and transposition ciphers, alongside the art and science of cryptanalysis, highlighting the ongoing battle between those who protect information and those who seek to unveil it. One intriguing fact is that cryptography's influence extends beyond military strategy to impact diplomatic negotiations and personal liberties. The book argues that the history of cryptography and cryptanalysis reflects broader social, political, and technological forces. It begins by introducing fundamental concepts like encryption and decryption, then traces their development through major historical periods, each addressed in distinct chapters. For example, the rise of mechanical cipher devices like the Enigma machine during World War II demonstrates the escalating sophistication of encryption methods. The book uniquely combines technical explanations with comprehensive historical analysis, emphasizing the practical implications of these techniques in modern digital security and data protection.

Secret Codes unveils the hidden history and science of cryptography, exploring how codes and ciphers have shaped communication through the ages. From protecting military intelligence to safeguarding digital privacy, this book examines the evolution of secret communication. It reveals how cryptography isn't just a technical field, but a reflection of human ingenuity and the constant need for security. Did you know the Caesar cipher, used in ancient Rome, was one of the earliest forms of substitution? Or that the Zimmerman telegram played a crucial role in World War I, demonstrating the impact of codebreaking on international relations? The book explores historical contexts, scientific principles, and practical applications, highlighting the ongoing battle between code makers and codebreakers. Beginning with fundamental concepts like substitution and transposition ciphers, the narrative progresses through key historical moments and mathematical underpinnings. Chapters delve into the development of codes from ancient times to modern cybersecurity applications, examining both symmetric and asymmetric cryptography. By combining historical analysis with accessible explanations of complex scientific concepts, Secret Codes offers a comprehensive understanding of cryptography's evolution and its impact on our world.

During the Second World War, Australia maintained a super-secret organisation, the Diplomatic (or `D’) Special Section, dedicated to breaking Japanese diplomatic codes. The Section has remained officially secret as successive Australian Governments have consistently refused to admit that Australia ever intercepted diplomatic communications, even in war-time. This book recounts the history of the Special Section and describes its code-breaking activities. It was a small but very select organisation, whose `technical’ members came from the worlds of Classics and Mathematics. It concentrated on lower-grade Japanese diplomatic codes and cyphers, such as J-19 (FUJI), LA and GEAM. However, towards the end of the war it also worked on some Soviet messages, evidently contributing to the effort to track down intelligence leakages from Australia to the Soviet Union.
