Sarthak Singh worked on the CipherTrust_Application_Protection repository, focusing on a targeted bug fix to improve the reliability of PKCS#11 key attribute display. Using C programming and cryptography expertise, Sarthak corrected the retrieval and formatting of key attributes such as CKA_PUBLIC_EXPONENT, CKA_PRIVATE_EXPONENT, and CKA_MODULUS_BITS within pkcs11_sample_helper.c. This update ensured that both public and private key information was accurately presented, reducing the risk of misinterpretation in security tooling and end-user outputs. The fix was localized to minimize impact on other modules, reflecting a careful approach to code quality and maintainability in cryptographic attribute handling.
