During October 2024, Durum Crustulum enhanced the qarmin/rustls repository by generalizing the hybrid key exchange mechanism for TLS 1.3 and adding standalone MLKEM768 support. Working primarily in Rust, Durum refactored the rustls-post-quantum crate to introduce modular implementations for both hybrid and MLKEM algorithms, improving maintainability and future extensibility. Updates to the bogo crate ensured correct handling of new key exchange types, which improved interoperability and client compatibility for post-quantum TLS. The work demonstrated depth in cryptography and key exchange algorithms, focusing on security posture and laying groundwork for future algorithm upgrades without addressing bug fixes during this period.
