Worked on the gardenlinux/package-linux repository to enhance the security of cryptographic testing by removing the SHA-1 algorithm from the crypto test manager. This update was implemented in C and focused on achieving FIPS compliance, thereby aligning the testing workflow with modern security standards and reducing exposure to deprecated cryptographic methods. The approach improved regulatory compliance and strengthened the reliability of crypto-related tests, addressing long-term security risks. By focusing on cryptography and security compliance, the work laid a foundation for further hardening of the crypto test suite and supported the broader migration toward FIPS standards within the repository’s codebase.
