===== Install hashcat =====

<code bash>
sudo apt install -y hashcat
</code>

===== Get hashcat information =====

<code bash>
hashcat -I
</code>

returns:

====== Benchmark ======

<code bash>
hashcat -b | uniq
</code>

returns:

<code bash>
hashcat (v6.2.5) starting in benchmark mode

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
