Note: this guide was written when Parrot shipped the beignet OpenCL driver. On a current release, first run hashcat -I to see which OpenCL devices Hashcat detects. If none are listed and you only need a CPU runtime, the PoCL package from the repository is the simplest option: sudo apt install pocl-opencl-icd. The Intel runtime steps below are kept for reference.
1. Why?
- Your machine has no AMD / Nvidia graphic card, but you still want to use hashcat.
- You want it more stable and faster than pre-installed driver (beignet)
- Hashcat doesn’t detect your devices (even if beignet was pre-installed)
2. How?
- Remove beignet:
sudo apt purge beignet
- Download
opencl_runtime_16.1.2_x64_rh_6.4.0.37.tgzfromhttp://registrationcenter-download.intel.com/akdlm/irc_nas/12556/opencl_runtime_16.1.2_x64_rh_6.4.0.37.tgz. Currently, Intel opencl has github project with 18.X versions. All 18.X versions don’t work for me, and 16.1.2 version is latest workable version I can find. - Extract downloaded file
tar -xvf opencl_runtime_16.1.2_x64_rh_6.4.0.37.tgz
Then run
install.sh
If you have missing libraries in this step (screenshot bellow), you can exit installation and install libraries. If there is only lsb-core>=4.0 is missing, you can move to next step (it worked for me).
– Accept their license, choose next and wait.
– Hashcat now detect my devices (it shows error with beignet driver)
– Benchmark is not very fast (compare AMD / Nvidia devices) but it looks faster than beignet
