How to hack Wifi Password with Kali Linux 2.0 ( Crunch )

HACK LIKE A PRO

In many of our password cracking disciplines, we often need to use a wordlist that will essentially attempt thousands of potential passwords per second. This is often referred to as a dictionary attack, even though we need not rely solely on dictionary words. These wordlists may have any combination of characters and words in an attempt to crack a complex password offline.

Sometimes we may have indications of the target's choice password or password components which may come from our knowledge of the target, e.g. girlfriend, neighbor, friend, etc. It could be their name, children's names, a pet's name, birthday, or job. We may also know the organization's password policy (e.g. minimum 8 characters, uppercase and lowercase, etc.).

In these cases, we may be able to generate a custom wordlist that reflects our knowledge of the target or the organization's password policy.

Kali Linux has built into it a tool called "crunch" that enables us to create a custom password-cracking wordlist that we can use with such tools like Hashcat, Cain and Abel, John the Ripper, Aircrack-ng, and others. This custom wordlist might be able to save us hours or days in password cracking if we can craft it properly.
