The master sets the base station password periodically to something new. The new password is based on a SHA1 hash of the date and a shared secret. The client simply displays what the current key is. The readme file is *much* more detailed than this page.<\/p>\n<p>It&#8217;s based on the Airport Base Station Configurator so SaferWep should work with the same range of products.<br \/>\nThe key is currently generated by taking a shared password and computing a SHA1<br \/>\nhash of the password with the current system date.
