Discover how to take advantage of common cryptographic operations to build safer apps that respect users privacy with the help of examples in JavaScript for Node.js and browsersKey Features:Understand how to implement common cryptographic operations in your code with practical examplesLearn about picking modern safe algorithms, which libraries you should rely on, and how to use them correctlyBuild modern and secure applications that respect your users privacy with cryptographyBook Description:If youre 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, youll learn about the common categories of cryptographic operations that you can leverage in all apps youre developing, including hashing, encryption with symmetric, asymmetric and hybrid ciphers, and digital signatures. Youll 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, youll 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, youll 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 protection requirements, and unlock new opportunities.What You Will Learn:Write JavaScript code that uses cryptography running within a Node.js environment for the server-side or in frontend applications for w
