JSON Web Token (JWT) is a standard that allows you to securely transmit data between parties as a self-contained JSON object. This course will teach you exactly how JWTs work and how best to use them, regardless of your programming language or framework.

JSON Web Tokens (JWT) are a security token format popular in protocols such as OAuth2 and OpenID Connect. In this course, JWT Fundamentals, you’ll learn about the JSON Web Token (JWT) standards and how to use them effectively. First, you’ll explore why JWTs exist, when to use them, and when not to. Next, you’ll discover how JWTs are protected using signing and encryption. Finally, you’ll learn security best practices for using and validating JWTs. When you’re finished with this course, you’ll have the skills and knowledge of JWTs needed to use them effectively in any programming language or framework.
