Description:

A CAPTCHA is a "Completely Automatic Public Turing Test to Tell Computers and Humans Apart." This implementation will create an image that displays a random key against a noisy background.

This image can then be used by a web page to require a user to enter the key into a text field. The user's input will be compared against the digest created from the original key to see if they really read the image or not.

This can be used to prevent automatic registrations by bots, for instance.
