The jsonwebtoken package provides a way to create and verify JSON Web Tokens (JWTs), which are compact, self-contained tokens commonly used for authentication and secure data transmission between services. It supports both symmetric signing (shared secret keys) and asymmetric signing (public/private key pairs), making it flexible for different security scenarios. Developers use this package to implement stateless authentication, validate user sessions, and securely transmit claims in web applications and APIs.
