Where can I find the code to add a 'protected sign-in' to an existing website?

I don't think that is the correct terminology, but it's the type of sign-in that requires a person enter a random word into the sign in box (like that used on Google AdWords Keyword Tool site.

Thanks.

It's called a CAPTCHA script. I had someone at rentacoder.com set one up for me. They're usually done with PHP. If you Google "free CAPTCHA script" I bet you can find something.
