Even faster hash decoding


Our client used an industry standard tool called hashcat to decode encrypted data. They were quite happy with the performance, but wanted a simpler and easier to maintain solution that they could integrate into their existing software.


Software Supreme created an easy to integrate library, coupled with an application for testing that uses CUDA driver API to optimally leverage the performance of a multi-gpu NVIDIA system. Using low-level optimizations for reducing divergence and improving register pressure we were able to beat the performance of hashcat for all required algorithms.


The client easily integrated our library into their project. Our solution supported all the required algorithms. The hardware was fully utilized. One of the algorithms achieved a 12x performance increase compared to the reference solution.
