Feel free to pick any other issue you want from https://github.com/magnumripper/JohnTheRipper/issues (just tell us you'll be looking into it so we don't end up doing same things) or just implement a new format of your choice (perhaps one we have as CPU-only), or optimize an existing one if possible. CUDA or OpenCL, that's up to you. BTW another thing you could try if you like, is CUDA auto-tuning. Many of our OpenCL formats auto-tune their local/global worksizes at startup (and we're moving towards using as much shared code as possible for that). All our CUDA formats currently have hard-coded threads/blocks, defaulting to figures non-optimal for high-end GPUs. magnum
