Aircrack-ng is a type of keys cracking software that primarily recovery 802.11 WPA-PSK and WEP keys but that is enough packets of data are already captured. This program implements two types of attacks which are the standard FMS attack and PTW attack, plus KoreK attacks for optimizations. These make each and every attack to work quicker than using cracking tools for WEP. Aside from that, Aircrack-ng is actually a toolset that enables auditing of wireless networks, 802.11 in particular. Cracking keys by this software product involves three steps only. The first step is to determine the chipset in the wireless card used. Secondly, there are three options to select from to run this program. These three options are through Linux distribution, CD and VMWare image – all of these three must contain the latest version of Aircrack-ng Suite. Last, but not the least, start running the program to crack WEP keys and WPA-PSK keys.
