I ran across this the other day and thought it was worthy of mentioning here. I have been writing some apps in php that have client side login screens that more or less could be hacked through brute force attempts just like any other web login form out there (including your online banking account…). This google password strength api is probably one of the better ones I have ever seen, I can remember thinking this also a while back when i signed up for some of my other google services. This article has links to download tar’d and gzip’d versions of the api source code as well as some demo helps which is always pretty cool to have…
