About jwt
The JWT extension provides functionality to decode and work with JWT (JSON Web Token) directly in DuckDB SQL queries.
Features
jwt_decode_payload(token): Decodes the payload part of a JWT token and returns it as a JSON string- Base64 URL-safe decoding for JWT token components
Use Cases
- Analyzing JWT tokens in your data
- Extracting claims from authentication tokens
- Debugging JWT-based authentication systems
- Working with JWT tokens in data pipelines
You can combine the JWT functions with DuckDB's built-in JSON functionality to extract specific claims from tokens.
