Contributed to the hashcat/hashcat repository by developing GPU-accelerated RACF KDFAES hash cracking support, enabling analysis of IBM mainframe hashes within the cracking engine. Leveraged C and OpenCL to implement cryptographic routines for DES, AES, SHA-256, and PBKDF2, integrating these algorithms into the existing codebase. Improved maintainability by removing outdated kernel and module files related to legacy RACF KDFAES support, reducing technical debt and streamlining future development. Standardized module naming and addressed code issues to enhance reliability and ease onboarding for new contributors. The work expanded hash format coverage and optimized performance for cryptographic analysis and hash cracking workflows.
