An all-practical guide to the cryptography behind common tools and protocols that will help you make excellent security choices for your systems and applications. \n \nIn Real-World Cryptography, you will find: \n

Best practices for using cryptography
Diagrams and explanations of cryptographic algorithms
Implementing digital signatures and zero-knowledge proofs
Specialized hardware for attacks and highly adversarial environments
Identifying and fixing bad practices
Choosing the right cryptographic tool for any problem

\nReal-World Cryptography reveals the cryptographic techniques that drive the security of web APIs, registering and logging in users, and even the blockchain. You’ll learn how these techniques power modern security, and how to apply them to your own projects. Alongside modern methods, the book also anticipates the future of cryptography, diving into emerging and cutting-edge advances such as cryptocurrencies, and post-quantum cryptography. All techniques are fully illustrated with diagrams and examples so you can easily see how to put them into practice.

\nabout the technology \nCryptography is the essential foundation of IT security. To stay ahead of the bad actors attacking your systems, you need to understand the tools, frameworks, and protocols that protect your networks and applications. This book introduces authentication, encryption, signatures, secret-keeping, and other cryptography concepts in plain language and beautiful illustrations.

\nabout the book \nReal-World Cryptography teaches practical techniques for day-to-day work as a developer, sysadmin, or security practitioner. There’s no complex math or jargon: Modern cryptography methods are explored through clever graphics and real-world use cases. You’ll learn building blocks like hash functions and signatures; cryptographic protocols like HTTPS and secure messaging; and cutting-edge advances like post-quantum cryptography and cryptocurrencies. This book is a joy to read—and it might just save your bacon the next time you’re targeted by an adversary after your data.
