Encrypting your wireless internet access requires an encryption key, and Wireless Key Generator not only can provide you with this it can save your key to a text file ready for storing on a usb memory stick or CD. Giving you a simple means of entering you key on each wireless device requiring a secure internet access. Although Wired Equivalent Privacy (WEP) is supported it is no longer recommended due to the number of programs available that can crack and determine the encryption key within seconds. So Wi-Fi Protected Access (WPA/WPA2) should be used if possible on all wireless access points and routers.
