How to Hack Wi-Fi: Cracking WPA2-PSK Passwords Using Aircrack-Ng.
@ By Parth When Wi-Fi was first developed in the late 1990s, Wired Equivalent Privacy was created to give wireless communications confidentiality. WEP, as it became known, proved terribly flawed and easily cracked. You can read more about that in my beginner's guide to hacking Wi-Fi . As a replacement, most wireless access points now use Wi-Fi Protected Access II with a pre-shared key for wireless security, known as WPA2-PSK. WPA2 uses a stronger encryption algorithm, AES, that's very difficult to crack—but not impossible. My beginner's Wi-Fi hacking guide also gives more information on this. The weakness in the WPA2-PSK system is that the encrypted password is shared in what is known as the 4-way handshake. When a client authenticates to the access point (AP), the client and the AP go through a 4-step process to authenticate the user to the AP. If we can grab the password at that time, we can then attempt to crack it. In this tutoria...
