To start using the cryptographically secure number generator, move
your mouse until the bar turns green.
This page will let you generate random passwords based on the characters
you want to use. This is great for pretty secure passwords for sensitive
systems, wireless encryption keys, and as source data for other programs.
If the bar above is red, it uses the browser's random number generator,
which isn't really that secure. If you move your mouse around a bit and get
that bar to be orange or better, it uses a better random number generation
technique, and that will generate even better passwords.
If you want to make WEP keys, click on "Hex" and then on the length of
the WEP key you want to make (10, 26, 58).
