- Add support for the OAuth Device Authorization Flow (RFC 8628) in the OpenAPI service, allowing devices with limited input capabilities to obtain authorization.
- Implement `DeviceAuthorization()` and `AuthorizeDevice()` methods to handle device and user code generation, storage, and authorization.
- Update the OAuth endpoints to include `/device/authorize` for user code authorization and fix the discovery endpoint path for device authorization.
- Introduce MongoDB service in CI workflows for testing and enhance the unit test workflow with Redis setup.
- Update Go module dependencies to include necessary packages for the new features.
This commit significantly advances the OAuth capabilities of the application, enabling a more flexible authorization process for devices.
- Added the JWKS endpoint to return JSON Web Key Set in compliance with RFC 7517, including necessary security headers.
- Refactored the JWKS generation logic to retrieve signing certificates and construct the JWK from the RSA public key.
- Introduced comprehensive tests for the JWKS endpoint, validating response format, compliance, and security headers.
- Updated go.mod to include the MongoDB driver as a required dependency.
- Added dynamic client registration support in the OAuth service, implementing RFC 7591 for automatic client registration.
- Introduced methods for generating client IDs and secrets, validating registration requests, and creating client information.
- Enhanced authorization flow by validating client requests, redirect URIs, and response types.
- Implemented token management features, including token introspection, token exchange, and refresh token handling.
- Improved security with state parameter generation and validation, as well as code challenge methods for PKCE.
- Updated endpoint discovery and server metadata retrieval to include new features and capabilities.
- Deleted the OAuth interface and related types that were previously defined in the `interfaces.go` and `types.go` files, streamlining the codebase.
- Updated the `oauth.go` file to integrate user and client providers directly, enhancing the service's functionality and reducing complexity.
- Refactored the user information retrieval method to utilize the new user provider structure, ensuring compatibility with the updated architecture.
