During September 2025, Colmenero Sendra developed HMAC SM3 state copy support for the wolfSSL/wolfssl repository, focusing on cryptography and embedded systems using C. He enhanced the wolfSSL_HmacCopy function to correctly duplicate the internal i_hash and o_hash states when WOLFSSL_HMAC_COPY_HASH is defined, addressing the need for reliable SM3 hash state management during HMAC operations. This technical approach prevents state corruption and enables robust SM3-based HMAC workflows, laying a foundation for future interoperability and testing. The work demonstrated a deep understanding of cryptographic state handling and contributed to the reliability and extensibility of the wolfSSL cryptographic stack.
