HN CAPTCHA

HN CAPTCHA is a PHP class that generates a picture to use in forms that perform CAPTCHA tests (Completely Automated Public Turing to tell Computers from Humans Apart). After the test form is submitted, a key entered by the user in a text field is compared to determine whether it matches the text in the picture. It is a fork of ocr_captcha that features support for older versions of the GD library, hacking prevention, optional use of Web safe colors, support for the use of multiple random TrueType fonts, and more.
