JWT (JSON Web Tokens) for Authentication
JWT, or JSON Web Tokens, serve as a compact and secure method for transmitting information between parties in a web application. They consist of three parts: a header, a payload, and a signature. This structure allows for the easy verification of the sender’s identity and ensures that the information has not been altered.
In Java applications, JWTs allow for stateless authentication, meaning that the server does not need to maintain session information for each user. This is particularly beneficial for distributed systems, where maintaining a centralized session store can introduce complexity and performance issues. The use of JWTs simplifies user verification while enhancing scalability.
The primary features of JWT for authentication include:
- Self-Containment: JWTs carry all necessary information about the user, such as roles and claims.
