Contributed to the acidanthera/audk repository by implementing SM3 hashing support within the UEFI MdePkg, focusing on cryptography and embedded systems using C. The work involved defining GUIDs for the SM3 cryptographic algorithm and creating structures to support SM3 hashes and X.509 certificates in the UEFI environment. This addition enables SM3-based security features and aligns the UEFI stack with compliance requirements for SM3 usage. No major bugs were addressed during this period, with efforts concentrated on foundational feature development. The contribution lays the groundwork for future security enhancements across the UEFI stack, emphasizing standards-based cryptographic support and maintainability.
