Aircrack/Cracking
From charlesreid1
The Basics
To crack a WPA passphrase with aircrack is pretty simple, as long as the password is in the wordlist you feed aircrack.
$ aircrack-ng -w my_wordlist.txt my_capfile.cap
The Tricks
The tricks are all related to how you pick your wordlist.
Generating Raw Wordlists
You can create a raw wordlist using Cewl. You basically feed it a URL, and it will traverse links and build a wordlist from the results of the page. Be patient, and choose your max depth wisely (especially when using Wikipedia).
Also, Wikipedia is great for generating wordlists for sportsball fans, in case you're clewless about that stuff, like me.
$ cewl -v https://en.wikipedia.org/wiki/Seattle -d 1 -w seattle.txt
