During February 2026, Thatte enhanced the aws-greengrass/aws-greengrass-lite repository by improving the robustness of OSSL_STORE key loading when using PKCS#11 URIs. Working in C and leveraging expertise in cryptography and security, Thatte implemented logic to iterate over multiple store objects and reliably select the correct private key, addressing issues where PKCS#11 URIs could return several objects and cause unreliable key resolution. This targeted change reduced load-time failures and improved the reliability of secure communications, particularly in deployments interfacing with hardware security modules. The work demonstrated a focused, in-depth approach to strengthening TLS and authentication flows in production environments.
