This skill allows AI agents to work with JSON Web Tokens (JWTs). It can decode, verify, and generate JWTs, enabling secure authentication and authorization flows. The skill supports common JWT algorithms and claims verification.
When to use it
- Verifying user authentication: Confirm the validity of a JWT presented by a client application.
- Generating access tokens: Create new JWTs for authenticated users or services.
- Extracting user information: Retrieve data encoded within the claims section of a JWT, such as user ID or roles.
- Decoding JWTs for analysis: Decode an existing JWT to understand its structure and contents.
Key capabilities
- JWT Decoding
- JWT Verification
- JWT Generation
- Support for common JWT algorithms
- Claims verification
Example prompts
- "Verify this JWT: [paste JWT here]"
- "Generate a JWT for user 'john.doe' with role 'admin'."
- "Decode the following JWT and tell me the value of the 'email' claim: [paste JWT here]"
Tips & gotchas
The skill requires a secret key or public key to verify signatures, depending on the algorithm used in the JWT. Ensure you provide the correct key for accurate verification.
