In February 2025, Zhangcheng Zhang enhanced the openssl/openssl repository by implementing QUIC TLS End Of Early Data (EOED) handling and enabling 0-RTT support, focusing on improved QUIC-TLS interoperability and connection performance. Using C and leveraging expertise in API development and network protocols, Zhangcheng introduced the SSL_NO_EOED macro, updated handshake error propagation for EOED scenarios, and added comprehensive tests to validate EOED behavior. The work also exposed a new API to facilitate 0-RTT enablement for third-party QUIC stacks. This feature-rich contribution addressed latency reduction for reconnects and established a robust foundation for future QUIC-TLS integrations.
