I want to learn How to hack wifi password.

In computer security, a hacker is someone who focuses on security mechanisms of computer and network systems. There is a community and shared culture of expert programmers and networking wizards that traces its history back through decades to the first time-sharing minicomputers and the earliest ARPAnet experiments. The members of this culture were the first "hackers." Breaking into computers and breaking phone systems have come to symbolize hacking in popular culture, but hacking culture is much more complex and moralistic than most people know. Learn basic hacking techniques, how to think like a hacker, and how to gain respect in order to crack your way into the complex world of hacking.
