Discover how to leverage common cryptographic operations to build safer apps that respect users' privacy with the help of examples in JavaScript for Node.js and browsers.

Key Features:

Understand how to implement common cryptographic operations in your code with practical examples.

Learn about picking modern, safe algorithms, which libraries you should rely on, and how to use them correctly.

Build modern and secure applications that respect your users' privacy with cryptography.

Book Description:

If you're a software developer, this book will give you an introduction to cryptography, helping you understand how to make the most of it for your applications. The book contains extensive code samples in JavaScript, both for Node.js and for frontend apps running in a web browser, although the core concepts can be used by developers working with any programming language and framework.

With a purely hands-on approach that is focused on sharing actionable knowledge, you'll learn about the common categories of cryptographic operations that you can leverage in all apps you're developing, including hashing, encryption with symmetric, asymmetric, and hybrid ciphers, and digital signatures. You'll learn when to use these operations and how to choose and implement the most popular algorithms to perform them, including SHA-2, Argon2, AES, ChaCha20-Poly1305, RSA, and Elliptic Curve Cryptography. Later, you'll learn how to deal with password and key management. All code in this book is written in JavaScript and designed to run in Node.js or as part of frontend apps for web browsers.

By the end of this book, you'll be able to build solutions that leverage cryptography to protect user privacy, offer better security against an expanding and more complex threat landscape, help meet data privacy regulations, and enhance the overall security of your applications.
