Web-based Password Generator

This is a simple web-based password generator which uses 6-different styles of passwords that can fit personal preferences, or restrictions from websites that require the password in a certain format.

Everything is calculated in JavaScript locally, and the passwords are not sent to the server for logging. You should be able to download this code, and run it offline, if you're truly paranoid.

The project takes advantage of localStorage to save state across browser sessions. This is needed to keep track of which security level you prefer when generating and passwords, and if using the mouse entropy generator, saving the debiased true random data. localStorage is not a cookie and is never communicated with a web server.
