Wireless WEP Key Password Spy!

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools.

WirelessKeyView recovers all wireless network security keys/passwords (WEP/WPA) stored in your computer by the Wireless Zero Configuration service of Windows XP and by the WLAN AutoConfig service of Windows Vista. It allows you to easily save all keys to text/html/xml file, or copy a single key to the clipboard.

netsniff-ng is a free, performant Linux networking toolkit. The gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa. It contains the utilities netsniff-ng, trafgen, mausezahn, bpfc, ifpps, flowtop, curvetun, astraceroute.
