Overview What You Will Learn Curriculum Instructor

Course Overview

Applied JavaScript Cryptography equips developers with the skills to secure applications using modern cryptographic techniques. In today’s web-driven world, sensitive data constantly flows between browsers, servers, and applications. Understanding how to apply cryptography effectively in JavaScript helps safeguard information, prevent attacks, and build trust in digital services. This course bridges the gap between cryptographic theory and its practical application in JavaScript development.

This course begins with an introduction to the fundamentals of cryptography, including key concepts and the differences between symmetric and asymmetric methods. You will explore why cryptography is essential in JavaScript, the threats it addresses, and the libraries available for implementation. From working with the Web Cryptography API to applying advanced techniques such as HMAC, AES, and RSA, the course provides hands-on experience with both core and advanced algorithms. You will also learn to apply cryptography in browser environments, integrate two-factor authentication, and follow best practices for secure JavaScript implementations.

By the end of this course, you will confidently apply JavaScript cryptography techniques to protect applications, secure data exchange, and implement best practices for modern, resilient web development.
