You will need a system (or two systems) on which to run hashcat and John. Virtual machines (VMs) are useful for documenting and testing software, but they will be limited in the system resources you can use (number of CPU cores and GPUs).
Hashcat will require NVIDIA or AMD drivers for best effectiveness, and these are often easier to install in Windows. As such, you may want to set up hashcat in Windows, which is what we will walk through in this chapter.
