Aircrack-ng

Aircrack-ng will help to capture and display the activity on a Wi-Fi channel of a network you are allowed to test. With this software package you can test the network for various vulnerabilities, tracking all traffic movements (network audit). After all, WEP and weak WPA passphrases are far from ideal.

Among the main features is the cracking of WEP and WPA-PSK (WPA 1 and 2) keys, including their recovery. The suite covers four areas: monitoring, attacking (replay attacks, deauthentication and fake access points via packet injection), testing of Wi-Fi cards and drivers, and cracking. The program contains a number of useful tools. For example, Airodump-ng will help with the capture of data packets and give you full information about the network. And wesside-ng will restore the WEP keys automatically. Other tools can be found on the developers' website.

The cracking code relies on the OpenSSL or libgcrypt crypto libraries, and the whole suite is free, open-source software released under the GPL.

Aircrack-ng allows users to monitor Wi-Fi activity, test network vulnerabilities and recover WEP and WPA-PSK keys, enhancing network security.

Before proceeding to install the utility, you should carefully study the official documentation describing the network commands and additional functions. The program is focused on wireless networks only. On Windows, capture and injection work only with AirPcap adapters.
