This, when applied to password cracking, means that, if a single processor can calculate ten thousand hashes in a second, one GPU with a thousand cores can do ten million. That means reducing cracking times by a thousand or more.

Now we will use Hashcat in its GPU version to crack hashes by brute force. If you have Kali Linux installed on a computer with an Nvidia chip, you will need cudaHashcat. If it has an ATI chip, oclHashcat will be your choice. If you have Kali Linux on a virtual machine, GPU cracking may not work, but you can always install it on your host machine, there are versions for both Windows and Linux.
