JWT Generator

What is a JWT Generator?

A JWT (JSON Web Token) Generator is a security and development tool that creates JWT tokens for authentication and authorization in web applications, APIs, and microservices. JWTs are compact, URL-safe tokens that contain claims and are digitally signed to ensure integrity. This generator helps developers, security professionals, and system administrators create JWT tokens with custom headers, payloads, and signatures using various algorithms. Whether you're testing authentication, developing APIs, or learning about JWT structure, this tool provides accurate token generation.

How to Generate JWT Tokens?

Generating JWT tokens is simple:

1. Select Algorithm: Choose the signing algorithm (HS256, RS256, ES256, etc.) for your JWT token.
2. Configure Header: Set token type, algorithm, and optional header claims (kid, etc.).
3. Add Payload Claims: Enter standard claims (iss, sub, aud, exp, iat) and custom claims for your token payload.
4. Set Secret/Key: Provide the secret key or private key for signing the token (depending on algorithm).
5. Generate Token: Click generate to create the JWT token with header, payload, and signature, ready for use in authentication.

This tool is essential for developers testing authentication systems, security professionals creating test tokens, or system administrators generating JWTs for API authentication and authorization purposes.
