Developed a comprehensive usage sample and documentation for the CryptoHeaderModule within the ThalesGroup/CipherTrust_Application_Protection repository, focusing on accelerating integration and onboarding for external developers. The work centered on implementing CryptoHeaderModuleSample.cs in C#, demonstrating practical cryptographic operations such as encryption, decryption, and HMAC generation and verification. By updating the README with clear instructions for CryptoHeaderModule.dll, the contribution provided actionable guidance for API integration and sample development. This targeted feature addressed integration risk and improved developer readiness, reflecting a methodical approach to cryptography and documentation. The work was delivered as a single, cohesive commit during the month-long engagement.
