company list (optional) and a wordlist (optional) and creates username and

some common passwords cited by Chris Gates (carnal0wnage) and Rob Fuller
(mubix) in their talk "The Dirty Little Secrets They Didn't Teach You In
Pentesting Class" presented at Derbycon 2011. The passwords are transformed
using some of the best64 rules from hashcat.
