- What is a JWT token?
- A JSON Web Token (JWT) is a compact, URL-safe means of representing claims between two parties. It's commonly used for authentication and information exchange.
- How do I create a JWT token?
- Enter your payload data in JSON format, select your preferred signing algorithm, provide a secret key, and click 'Sign'. The tool will generate a signed JWT token instantly.
- What algorithms are supported?
- We support common JWT signing algorithms including HS256, HS384, and HS512 for HMAC-based signatures, and RS256, RS384, and RS512 for RSA-based signatures.
- Is my data secure when using this tool?
- Yes, all JWT operations are performed locally in your browser. Your keys and data never leave your device.
- What claims should I include in my JWT?
- Common claims include 'sub' (subject), 'iat' (issued at), 'exp' (expiration), and 'iss' (issuer). You can add any custom claims as needed for your application.
