PROFILE
Andrew Hutchings
Over two years, contributed to the wolfSSL/wolfssl repository by building and maintaining embedded cryptography features, hardware integrations, and automated testing infrastructure. Delivered cross-platform support for secure elements and microcontrollers, expanded CI pipelines with hardware-in-the-loop and emulator-based validation, and improved packaging and documentation for developer onboarding. Used C, Bash, and Python to implement cryptographic protocol fixes, memory management enhancements, and security hardening across TLS/DTLS, kernel, and network layers. Focused on reproducible builds, robust error handling, and compliance with evolving standards, the work enabled safer key management, accelerated regression testing, and improved reliability for embedded and cross-compiled cryptographic deployments.

Feb 1, 2025February 2025 (wolfSSL/wolfssl): Focused SE050 integration work to stabilize builds and expand secure element capabilities. Delivered a bug fix for the SE050 port build, including documentation updates, a missing preprocessor directive, standardization of integer types, resolution of an ECC.c compiler error, and enhanced debugging output to ensure compatibility with the latest wolfSSL. Added SE050 secure element features: AUTO_ERASE (automatic erasure of keys when ECC key free functions are called) and NO_RSA (disables RSA offloading to SE050 for devices without RSA support). These changes improve build reliability, security control, and device compatibility. Technologies involved include C, wolfSSL, SE050 secure element integration, preprocessor directives, type standardization, and improved debugging instrumentation. Business impact includes reduced build failures, safer key lifecycle handling, and greater flexibility across hardware variants.
