Worked on the OpenSSL repository to enhance stability and interoperability of TLS 1.3 session resumption, focusing on environments with varying character encodings. Addressed a critical bug by updating the nonce_label encoding to use ASCII hex, ensuring correct session ticket construction and processing across systems such as EBCDIC. This change reduced session resumption failures and improved cross-encoding compatibility for enterprise deployments. The solution was implemented in C, leveraging expertise in cryptography, network security, and system programming. The work underwent thorough peer review and was merged after CLA compliance, reflecting a careful approach to protocol internals and secure code maintenance.
