Fundamentals of Secure Software - JWT (JSON Web Token)

The video tutorial explains JSON Web Tokens (JWTs), an open standard for securely transmitting information between parties as a JSON object. JWTs can be signed using a secret or public/private key pair, ensuring the integrity and authenticity of the claims. They are commonly used for authorization, allowing users to access resources without maintaining a session on the server. The structure of a JWT includes a header, payload, and signature, with claims that can be registered, public, or private. The tutorial also covers the process of creating and verifying JWTs, emphasizing the importance of not including sensitive information unless encrypted.
