Developed cryptographic hashing utilities for the fledge-iot/fledge repository, focusing on secure data processing and storage. The work involved implementing a dedicated cryptography utilities module in C++ that supports both SHA-256 and MD5 hashing, ensuring compatibility across different OpenSSL versions. By integrating these hashing mechanisms, the developer enhanced the platform’s data integrity and security posture, laying groundwork for future cryptographic improvements. The approach emphasized modularity and reusability, allowing the new utilities to be leveraged throughout the codebase. This contribution addressed the need for standardized, reliable hashing within the project, utilizing expertise in C++, cryptography, and OpenSSL integration.
