Mar 1, 2025March 2025 monthly summary for wolfProvider focused on cryptography robustness, interoperability, and quality. Delivered several key features and bug fixes that improve correctness, security posture, and production reliability while enhancing integration capabilities with OpenSSH/OpenSSL. Key features and fixes delivered: - RSA key import and management fixes: corrected parameter validation, ensured correct key type on import, and implemented proper X931 padding handling with zero-padding to match signature length. - RSA verify recover functionality (PKCS1) support: initial implementation for verify-recover with PKCS1 padding, accompanied by tests to validate behavior. - HKDF salt handling robustness: HKDF now accepts NULL or zero-length salts and handles salts correctly across modes, with added test coverage. - AES-GCM IV handling for OpenSSH compatibility: refactor of IV handling to support the OpenSSH encryption/decryption flow reliably. - ECC parameter encoding for OpenSSL genpkey (named_curve): added support for named_curve encoding with mapping for common curves and tests. Overall impact and accomplishments: - Improved cryptographic correctness and reliability across RSA, HKDF, AES-GCM, and EC flows. - Increased interoperability with OpenSSH and OpenSSL, enabling smoother integrations and longer-term compatibility. - Expanded test coverage, reducing production risk and regressions in edge cases. Technologies/skills demonstrated: - Cryptography primitives and protocols (RSA/X931, PKCS1, HKDF, AES-GCM, EC named_curve) - Secure parameter handling, padding schemes, and encoding/decoding pathways - Python integration patterns and test-driven development for cryptographic routines - Code quality improvements through refactoring and robust validation
