Have you ever wondered how passwords are stored securely? What makes a good password? How codes and ciphers are designed—and broken? Where random numbers come from, and what makes them random? What are the connections between lava lamps, space games, digital signatures, black holes, and Bitcoin? Let's find out. Join Alice, Bob, Eve, and Mallory as we learn about the fundamental principles of cryptography and digital security, from brute force and blockchains to keyspaces and hashing. We'll build a cipher system in Go from scratch, with step-by-step instructions and code examples at each stage (also available on GitHub). Starting with the simplest cipher imaginable, we'll gradually improve the system by attacking it, adding sophisticated features like block chaining, padding, digests, and authentication. Along the way, you'll develop a powerful intuitive understanding of ciphers and keys, what makes them strong (or weak), and how to use them securely. We'll see how state-of-the-art modern algorithms like AES, SHA-256, Diffie-Hellman, and RSA work under the hood, and how to integrate them into real-world Go tools. This book is essential reading for all Go programmers who have to deal with encryption, authentication, and security... in other words, all of us! By reading through this book and completing the challenges, you’ll learn about: The fundamental principles of codes and ciphers Building software test-first in Go How to write useful command-line tools Password security, keyspaces, and cracking Blocks, streams, chains, and cipher modes Padding, number bases, and endianness Pseudo-random and true random number generators Entropy, complexity, and quantum uncertainty Attacks, nonces, and initialization vectors Message digests, integrity, and authentication MD5, SHA-1, SHA-256, and SHA-3 Rainbow tables, salts, and zero-knowledge proofs Cryptocurrencies, key exchange, and asymmetric encryption Public-key cryptography: Diffie-Hellman and RSA AES/Rijndael internals and implementations AES-256 and AES-GCM Modern cryptography with the Go standard library Post-quantum cryptography

The gold standard for attaining security is cryptography because it provides the most reliable tools for storing or transmitting digital information. Written by Niels Ferguson, lead cryptographer for Counterpane, Bruce Schneier's security company, and Bruce Schneier himself, this is the much anticipated follow-up book to Schneier's seminal encyclopedic reference, Applied Cryptography, Second Edition (0-471-11709-9), which has sold more than 150,000 copies. Niels Ferguson (Amsterdam, Netherlands) is a cryptographic engineer and consultant at Counterpane Internet Security. He has extensive experience in the creation and design of security algorithms, protocols, and multinational security infrastructures. Previously, Ferguson was a cryptographer for DigiCash and CWI. At CWI he developed the first generation of off-line payment protocols. He has published numerous scientific papers. Bruce Schneier (Minneapolis, MN) is Founder and Chief Technical Officer at Counterpane Internet Security, a managed-security monitoring company. He is also the author of Secrets and Lies: Digital Security in a Networked World (0-471-25311-1).

Cryptography is now ubiquitous – moving beyond the traditional environments, such as government communications and banking systems, we see cryptographic techniques realized in Web browsers, e-mail programs, cell phones, manufacturing systems, embedded software, smart buildings, cars, and even medical implants. Today's designers need a comprehensive understanding of applied cryptography. After an introduction to cryptography and data security, the authors explain the main techniques in modern cryptography, with chapters addressing stream ciphers, the Data Encryption Standard (DES) and 3DES, the Advanced Encryption Standard (AES), block ciphers, the RSA cryptosystem, public-key cryptosystems based on the discrete logarithm problem, elliptic-curve cryptography (ECC), digital signatures, hash functions, Message Authentication Codes (MACs), and methods for key establishment, including certificates and public-key infrastructure (PKI). Throughout the book, the authors focus on communicating the essentials and keeping the mathematics to a minimum, and they move quickly from explaining the foundations to describing practical implementations, including recent topics such as lightweight ciphers for RFIDs and mobile devices, and current key-length recommendations. The authors have considerable experience teaching applied cryptography to engineering and computer science students and to professionals, and they make extensive use of examples, problems, and chapter reviews, while the book’s website offers slides, projects and links to further resources. This is a suitable textbook for graduate and advanced undergraduate courses and also for self-study by engineers.

This book is intended as a text for a course on cryptography with emphasis on algebraic methods. It is written so as to be accessible to graduate or advanced undergraduate students, as well as to scientists in other fields. The first three chapters form a self-contained introduction to basic concepts and techniques. Here my approach is intuitive and informal. For example, the treatment of computational complexity in Chapter 2, while lacking formalistic rigor, emphasizes the aspects of the subject that are most important in cryptography. Chapters 4-6 and the Appendix contain material that for the most part has not previously appeared in textbook form. A novel feature is the inclusion of three types of cryptography - "hidden monomial" systems, combinatorial-algebraic sys tems, and hyperelliptic systems - that are at an early stage of development. It is too soon to know which, if any, of these cryptosystems will ultimately be of practical use. But in the rapidly growing field of cryptography it is worthwhile to continually explore new one-way constructions coming from different areas of mathematics. Perhaps some of the readers will contribute to the research that still needs to be done. This book is designed not as a comprehensive reference work, but rather as a selective textbook. The many exercises (with answers at the back of the book) make it suitable for use in a math or computer science course or in a program of independent study.
