I didn't make this. Some really smart people did and now other people are using it too.

Real Password Strength

This password strength meter uses some excellent logic to determine how likely a robot will be able to guess a password. Dan Wheeler of Dropbox, Inc. took on this project for hackweek at Dropbox. He "thought it’d be fun to build an open source estimator that catches common patterns, and as a corollary, doesn’t penalize sufficiently complex passphrases like correcthorsebatterystaple".

Password Strength

It’s now live on dropbox.com/register and available for use on github. Try the demo to experiment and see several example estimations.
