Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. The objective is to capture the WPA/WPA2 authentication handshake and then crack the PSK using aircrack-ng. With the help of these commands you will be able to crack Wi-Fi Access Points which use PSK (Pre-Shared Key) encryption. In this tutorial, we will use the latest version of the tool that allows us to crack the keys.”]
