How long does the cracking process take? I remember WEP only taking 10 minutes using aircrack-ng in BackTrace... I imagine this takes substantially longer.

>Naive-hashcat uses various dictionary, rule, combination, and mask attacks and it can take days or even months to run against strong passwords. The cracked password will be saved to hackme.pot, so check this file periodically.

So I don't have experience with WPA cracking, but if the access point has WPS (the click to connect button) you can sniff handshakes on the network and crack the WPA password it in relatively no time. In my experience this has usually been under 10 minutes.

4,733,979 out of the 14,344,391 passwords (33%) in the rockyou.txt dictionary file used for cracking in this guide are too short to be WPA2 passwords, which have a minimum length of 8 characters. Are aircrack and/or hashcat smart enough to not bother hashing those short passwords?

I attempted to do this once and it turned out to be monumentally difficult. I got as far as setting up a bootable kali thumb drive before getting stopped in my tracks by hardware incompatibilities and unexpected behaviors and errors. These articles make it sounds a LOT easier than it is. I was very disappointed because I was really excited about it.

(looks like the case for aircrack-ng, at least: https://github.com/aircrack-ng/aircrack-ng/blob/master/src/a...)

It's not for the faint of heart or faint of technical skill - different drivers have different behaviors and ways to enter the various capture and raw packet modes needed to do this.

Personally, as long as I stick to supported chipsets, I've almost never had an issue.
