howsecureismypassword.netEver wonder how ironclad your password is? Using a combination of mathematics, witchcraft and jQuery, HowSecureIsMyPassword.net lets you know approximately how long it would take a vicious, evil computer to crack your PW and break into the virtual fortress that houses your e-dentity. For example, if your password were password, it would take a matter of seconds, but if your password were P@$$w0rd, it would take about three years.

The site says that no passwords you enter are saved, but if you're worried you can always just enter in random characters and words.
