Worked on the openssl/openssl repository to deliver FIPS-focused feature enhancements, strengthening both security and compliance. Developed improvements to the RSA verify_recover path in C, adding output buffer size validation and explicit error handling to prevent overflows and ensure robust error reporting. Introduced regression tests using 2048-bit keys to align with FIPS requirements and reinforce reliability. Enhanced the testing framework by gating tests to run only with compatible FIPS providers, thereby reducing false failures and improving CI stability. Demonstrated expertise in C programming, cryptography, and software testing, with a focus on integrating FIPS provider compatibility and comprehensive regression coverage.
