Federico Aponte contributed to the grafana/falco repository by modernizing its cryptographic implementation in C++. He addressed a critical security issue by migrating SHA256 checksum computation from deprecated OpenSSL functions to the EVP API, ensuring compatibility with OpenSSL 3.x and aligning with current cryptographic standards. Federico implemented the full EVP digest workflow, including initialization, update, and finalization, to maintain accurate digest calculations. His work preserved repository stability, introduced no user-facing regressions, and improved long-term maintainability. By focusing on cryptography and secure API usage, Federico enhanced the codebase’s readiness for future OpenSSL upgrades while reducing maintenance and compatibility risks.
