Oct 1, 2024Monthly summary for 2024-10 focused on delivering encryption-related enhancements to Percona Server with alignment to MySQL Enterprise Encryption features (MySQL 8.0.30). Key work centers on EVP_PKEY and padding improvements for UDFs, and a new system variable to control legacy padding behavior. The work advanced cryptographic capabilities for user-defined functions, improved interoperability with enterprise components, and expanded test coverage to ensure correctness and regression safety. Highlights include: - EVP_PKEY and padding enhancements for UDFs, enabling evp_pkey usage and explicit padding control for asymmetric_sign() and asymmetric_verify(), plus new enums for EVP_PKEY algorithms and signature padding. Tests updated to reflect the new capabilities. - Legacy padding scheme system variable: component_encryption_udf.legacy_padding_scheme to set default padding when none is provided, aligning Percona UDFs with MySQL 8.0.30 enterprise features; tests added to verify behavior. - Alignment with MySQL 8.0.30 Enterprise Encryption Component (PS-8389) to improve compatibility and security posture. Impact: Enhanced security and interoperability for encryption-related UDFs, better configurability, and reduced maintenance risk through broader test coverage and enterprise-aligned behavior. Technologies/skills demonstrated: C++ cryptography interfaces (EVP_PKEY), UDF development, system variables, test-driven development, Git-based change management, and cross-component compatibility with MySQL Enterprise features.
