Andreas Vikerup
During April 2025, contributed a new cryptographic module to the hashcat/hashcat repository, enabling password cracking for hashes using double SHA-256 with salt. This work involved developing OpenCL kernels for efficient matching and searching, as well as implementing a C module for decoding and encoding hash formats. By leveraging SIMD optimization techniques, the module achieved higher throughput and performance. The addition expanded hashcat’s support for salted, double-hash schemes, enhancing its utility for security assessments and incident response. The project drew on expertise in C programming, cryptography, and OpenCL development, focusing on robust, high-performance password cracking capabilities for complex hash types.
