Briefly describe your issue below:
Hashcat can’t see my GPU (and thus can’t use it for decrypting).
sudo hashcat -I
Device ID #1
Type : CPU
… MORE OUTPUT ABOUT MY CPU…
Notice, there are not 2 devices, but there should be (CPU and GPU).
Before someone says it, I’ve followed Hashcat’s solution to an exact, and I’ve tried other forums but no luck.
I have GEFORCE GT 730
Let me know if you would like to see other outputs.
P.S. running “lspci -v” DOES show my graphics card, but hashcat doesn’t.
What version of Parrot are you running? (include version, edition, and architecture)
Parrot 4.4 64bit
What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)
Configured to multiboot with other systems? (yes / no)

You need to install some extra bits.
I had to install nvidia-cuda-toolkit and clinfo, then i was able to use hashcat.
Make sure your card supports ‘cuda’ first:
clinfo for debugging.
nvidia-cuda-toolkit totals over 2G of packages… I dont know if all those packages are needed, so it might be overkill.
After i installed
nvidia-cuda-toolkit it didnt show up in hashcat straight away, but after i had done some de-bugging i checked back and it was working. Was a bit odd since i didnt change anything, so make sure you reboot afterwords ect just to make sure.
So just tried on another machine and got it working.
sudo apt update
sudo apt-get install nvidia-cuda-tookit
sudo apt-get install clinfo
You should now see the card.
I will try doing this soon, but my GPU was not on the CUDA supported list on that link you sent. Should I even bother trying?
I know Parrot supports my card (as the website says and lspci shows), but is hashcat CUDA specific or is there another method?
So here is a different set of lists
I only linked GeForce cards on that post. You can see how many CUDA cores your card has in the ‘Nvidia X server’ application.
Hashcat uses OpenCL, nvidia uses CUDA, CUDA supports OpenCL. If that makes sense.
Nvidia > CUDA > OpenCL > Hashcat.
After that it bricked my OS. Now I have to reinstall. Anybody else have suggestions?
For intel CPU and GPU (onboard), You should find and install intel-opencl version 16. Intel released version 18 on github and it doesn’t work for me. I don’t know about AMD / NVIDIA graphic card so i guess you can ask about it on hashcat forum.
if your HW isnt on the list it may not be supported. whats the gpu?
sudo apt install -y ocl-icd-libopencl1 nvidia-driver nvidia-cuda-toolkit should work perfectly.
