Summary
🤩
RockstarZhi Guan is a researcher and software engineer with 11 years of experience focused on cryptography and secure communications, currently based at Peking University. He has hands-on expertise implementing TLS 1.3 features and integrating Chinese national cryptographic algorithms (SM2, SM3, SM4, SM9) into production-grade tooling, notably contributing core GCM record-layer encryption/decryption and certificate handling to the GmSSL project. His work bridges academic research and practical backend engineering, delivering interoperable security primitives rather than just prototypes. Comfortable navigating low-level protocol internals, he brings a track record of making cryptographic standards usable in real systems. Colleagues value his blend of rigorous research thinking and pragmatic code contributions that prioritize correctness and interoperability.
