In this course, I have talked about the underlying concepts of what happens when we type in a password from a phone or a PC and click on "Connect to WiFi". Starting from How passwords are stored and as days went by, how passwords are not directly shared over the Wires or Wireless, instead how Authentication is done by using Hashes, and just for Authentications, How using a hash could be risk worthy and the way to bypass that and how all of those vectors round up to the building blocks of a WPA2 Personal transaction. Then I have described how exactly the popular WPA2 Password Cracking works by using the AirCrack package.
