Subhendu Kundu developed a comprehensive usage sample and documentation for the CryptoHeaderModule within the ThalesGroup/CipherTrust_Application_Protection repository. He implemented CryptoHeaderModuleSample.cs in C#, demonstrating end-to-end cryptographic operations such as encryption, decryption, and HMAC generation and verification. His work focused on API integration and sample development, providing clear, practical examples to accelerate customer onboarding and reduce integration risk. By updating the README with detailed usage instructions for CryptoHeaderModule.dll, Subhendu improved external developer readiness. The depth of the sample and documentation addressed real integration challenges, supporting smoother adoption of CipherTrust Application Protection in customer environments.
