I came across this infosthetics blog post discussing a Javascript interface for doing Chroma password.
I hadn’t yet had a chance to dive into any Flex 4 stuff, so I thought this might be a good little opportunity to play around with it. My algorithm isn’t exactly as described in the blog post, but it seems to work effectively. I’m using a portion of the SHA256 hash to generate the various colors. I’m animating between colors so as long as you type more than 1 character every 1/2 second, a screen grabber can’t grab the intermediary colors and figure out your password through trial/error.
This type of component is useful for ensuring that a person has entered their password correctly or to help them notice right away that their capslock key was on while typing it.
