…orithm and validation - **Certificate Ordering (OrderCertificatesTrait):** - Implement new leaf-first ordering algorithm with proper chain building - Add Distinguished Name normalization for reliable certificate comparison - Introduce comprehensive chain validation with `validateCertificateChain()` - Handle complex multi-level certificate hierarchies and edge cases - Improve error handling with detailed validation messages - **PDF Signature Processing (Pkcs12Handler):** - Refactor `getCertificateChain()` method with extracted helper functions - Improve TSA timestamp processing and certificate chain extraction - Clean up code organization and remove unnecessary comments - Enhance certificate data enrichment from Poppler utilities - **Test Coverage Improvements:** - Add 300+ lines of comprehensive test cases covering real-world scenarios - Include banking, corporate, and e-commerce certificate chain examples - Add validation tests for complete, incomplete, and invalid chains - Refactor Pkcs12Handler tests to focus on public interface without reflection - Remove excessive mocking in favor of behavioral testing - **Code Quality:** - Follow best practices by testing only public methods - Eliminate reflection-based testing for better maintainability - Improve test reliability and reduce brittleness to internal changes - Clean up code structure and remove redundant documentation This enhancement significantly improves certificate chain handling reliability for digital signature validation in LibreSign, with comprehensive test coverage ensuring robustness across various PKI scenarios.
