Complexify – jQuery Password Strength Plugin

Complexify helps you to accurately gauge the quality of a user’s password to give them visual feedback, and to enforce a minimum level of security.Complexify 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.Note: I use the term ‘casually’ because this is only client-side validation and anyone could turn it off. I recommend implementing a minimum length check server-side as well. In the future I may code up this algorithm for use server-side.
