PROFILE
C0rs
During May 2025, 0xc0rs developed GPU-accelerated RACF KDFAES hash cracking support for the hashcat/hashcat repository, enabling analysis of IBM mainframe hashes. They implemented OpenCL kernels and integrated cryptographic algorithms including DES, AES, SHA-256, and PBKDF2 into the cracking engine using C and OpenCL. Their work included refactoring code, removing outdated kernel and module files to reduce technical debt, and standardizing module naming for improved maintainability. By expanding hash format coverage and enhancing performance, 0xc0rs addressed both technical and operational challenges, demonstrating depth in cryptography, code refactoring, and reverse engineering within a complex, security-focused codebase.
