Complexify is a jQuery plugin for checking password strength and quality. It aims to provide a good measure of password complexity for websites to use both for giving hints to users in the form of strength bars, and for casually enforcing a minimum complexity for security reasons.
Complexify supports Unicode and will add appropriate complexity for the size of character set included in a password.
It’s a client-side validation and author recommends implementing a check for the minimum length on the server, but plans to have a complementary server-side library that will enable developers to have a consistent policy set up throughout their service.
