WirelessKeyView recovers all wireless network 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.
New and safer method to extract the wireless keys of the local machine: In previous versions, WirelessKeyView injected code into lsass.exe in order to grab the wireless keys from the system. In rare cases, this technique caused a crash inside lsass.exe process. Starting from this version, WirelessKeyView uses a new method that extract the wireless keys without any code injection.
