Worked on the openssl/openssl repository to address a critical issue in the SSL library involving GOST signature algorithm naming. Delivered a targeted bug fix in C that resolved incorrect and ambiguous identification of GOST 512 and GOST2012 signature algorithms, removing problematic aliases to prevent confusion during TLS handshakes. The solution improved cryptographic correctness and interoperability, ensuring proper sigalg identification for both legacy and modern GOST implementations. Collaborated closely with core maintainers, incorporating extensive peer feedback before merging the changes. Demonstrated expertise in C programming, SSL/TLS development, and cryptography, contributing to the reliability and security of OpenSSL’s cryptographic operations.
