If you've ever connected to a wireless network from your PC, notebook or netbook, you surely have some of the wireless key data stored on your computer somewhere and it's most likely found in your system registry. If you've ever tried to retrieve those lost wireless network passwords, you're normally up against a brick wall as network keys are hidden behind asterisks (actually, bullets) by default.
WirelessKeyView is a totally free application which allows users to retrieve saved WEP and WPA passwords from their system and from within the main user interface, you can view the key (hex code), the key type and the plain text key used to access the wireless network.
Once you've found all of the keys you have saved on your system, WirelessKeyView can export those known keys to a text file or a couple of other formats the program supports (HTML/TXT/XML).
As usual with most NirSoft products, this one is completely free.WirelessKeyView 1.68
