If you’re browsing the web, using public APIs, making and receiving electronic payments, registering and logging in users, or experimenting with blockchain, you’re relying on cryptography. And you’re probably trusting a collection of tools, frameworks, and protocols to keep your data, users, and business safe. It’s important to understand these tools so you can make the best decisions about how, where, and why to use them. Real-World Cryptography teaches you applied cryptographic techniques to understand and apply security at every level of your systems and applications.

about the technology

Cryptography is the foundation of information security. This simultaneously ancient and emerging science is based on encryption and secure communication using algorithms that are hard to crack even for high-powered computer systems. Cryptography protects privacy, secures online activity, and defends confidential information, such as credit cards, from attackers and thieves. Without cryptographic techniques allowing for easy encrypting and decrypting of data, almost all IT infrastructure would be vulnerable.

about the book

Real-World Cryptography helps you understand the cryptographic techniques at work in common tools, frameworks, and protocols so you can make excellent security choices for your systems and applications. There’s no unnecessary theory or jargon—just the most up-to-date techniques you’ll need in your day-to-day work as a developer or systems administrator. Cryptography expert David Wong takes you hands-on with cryptography building blocks such as hash functions and key exchanges, then shows you how to use them as part of your security protocols and applications. Alongside modern methods, the book also anticipates the future of cryptography, diving into emerging and cutting-edge advances such as cryptocurrencies, password-authenticated key exchange, and post-quantum cryptography. Throughout, all techniques are fully illustrated with diagrams and real-world use cases so you can easily see how to put them into practice.

A very detailed book on everything cryptographic. Hashing, authentication, hand-shaking, it's all there.

Eddy Vluggen

Explores the origins, use and construction of cryptography in the modern world.

Shawn Bolan

It's amazing how the author has found a way to explain cryptography in such simple terms.

Adhir Ramjiawan

I highly recommend this book to anyone fascinated but intimidated by the world of cyber and data security who is looking for an easier way to learn the practical aspects of this exciting subject!

Al Rahimi

A best-in-category book taking you all the way from curious novice to confident practitioner.

William Rudenmalm

If you are busy and want to know how encryption works—this is the best choice. A lot of examples in an easy language to digest.
