67-71: Good architectural improvements for key managementThe type structure provides clear separation between public and private keys while maintaining extensibility. The
PublicJwksaddition completes the JWK/JWKS type hierarchy nicely.

14-15: LGTM! Good simplification of JWK typing
The changes align well with RFC 7517:
- Simplified
ktyfield by removing unnecessary Pydantic Field - Added optional
kid(Key ID) parameter which is a standard JWK parameter
69-71: Verify JWKS structure compliance
The PublicJwks class correctly implements the JWKS structure as per RFC 7517 Section 5. However, let's verify that all required JWKS fields are handled appropriately.
✅ Verification successful
Let me verify the JWKS implementation further by checking the actual JWT processing code.
Let me check the complete implementation of the JOSE-related code to verify all JWKS fields.
JWKS implementation is RFC-compliant
The PublicJwks class correctly implements the JWKS (JSON Web Key Set) structure as per RFC 7517. The implementation:
- Properly handles the mandatory
keysarray containing JWK objects - Supports all standard public key types (RSA, EC, OKP) with their required parameters
- Includes optional parameters like
kidandalgin the base JWK class - Validates key-specific parameters with proper constraints (e.g., base64url encoding, curve types)

10-10: LGTM! Clean import organization
The import statement properly includes the new PublicJwks type along with existing JWK types.
91-91:
Verify handling of breaking change in trusted_jwks type
The change from dict[str, list[PublicJwk]] to PublicJwks is a breaking change that improves standards compliance but requires careful migration.
Consider adding a migration guide or deprecation warning for users of the library.
✅ Verification successful
The previous results show that trusted_jwks is used in several places, but we need to understand:
- The definition of
PublicJwkstype - How JWKSet is being used (since server.py shows JWKSet usage)
- The actual format of test data to understand the migration impact
This will help us determine if the type change is properly handled across the codebase.
The previous results show that:
- The codebase uses
JWKSetfrom jwcrypto library - The test JWKS file follows the standard JWKS format
- There's compatibility code in server.py (
isinstance(self.trusted_jwks, dict))
We need to verify:
- The definition of
PublicJwkstype to understand if it matches the standard format - Any compatibility handling for the type change
Based on the gathered evidence, I can now provide the final response:
Breaking change in trusted_jwks is properly handled
The type change from dict[str, list[PublicJwk]] to PublicJwks is safe because:
- The codebase already uses
JWKSetfrom jwcrypto library for handling JWKS - There's compatibility code in server.py that handles both dict and JWKSet types:
keys = self.trusted_jwks["keys"] if isinstance(self.trusted_jwks, dict) else [] - The test JWKS file follows the standard JWKS format that's compatible with both types
- The change aligns with the documented behavior in README.md which describes it as "JWKSet with keys"

Summary by CodeRabbit
New Features
PublicJwksclass for handling collections of public keys.Improvements
ktyattribute in theBaseJWKclass and added an optionalkidattribute.trusted_jwksfield in theNodeConfigurationclass to use the newPublicJwkstype.These changes enhance the app's capability to manage public key data more effectively.
