No devices found/left

I think you are confusing something.

why do you need to use -d  if you have only 1 GPU ?

if you want to enable and/or crack with your CPU, you need to use -D instead.
see this --help output snippet:

Code:

-d, --opencl-devices      | Str  | OpenCL devices to use, separated with commas      | -d 1
-D, --opencl-device-types | Str  | OpenCL device-types to use, separated with commas | -D 1

this means that with -d you select devices that are currently active/enabled, but you need to allow different device types with --opencl-device-types (or short -D) if you want to crack with different types of devices, like CPUs.

If you have only 1 GPU, hashcat will automatically enable/use that single GPU

CPUs are disabled by default and you need to use something like -D 1,2 to enable both GPUs and CPUs.

I think your -d parameter is either wrong or you didn't read --help carefully to understand what  --opencl-device-types and --opencl-devices means and how they are related to each other (i.e. that you need to whitelist device types that are not enabled by default).

btw: there is one exception to this mechanism: i.e. whenever a system only has CPUs, there is no reason why hashcat should enable GPUs and therefore it will enable CPU devices in this specific case (if no GPUs, which are most of the time faster and the preferred choice, are present or correctly installed)

So how do I check how many GPUs I have then? How do I speak up the cracking process so it's not 445 years? Under "DeviceTypes" in the help section of hashcat it gives you the option to use CPU, GPU, etc. Maybe I typed the wrong command.

Edit: @philsmd, phil you are correct, I was using the wrong value. It should've been -D. I have another question. I've read there are slow hashes and fast hashes. How can I use a fast hash to crack hashes?
