Cracking password hashes by brute force using oclHashcat/cudaHashcat

In recent years, the development of graphics cards has evolved enormously, the chips they include now have hundreds or thousands of processors inside them and all of them work in parallel. 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, ...
