This package provides the functionality to create CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart). Features include:
Creating graphical CAPTCHAs using GD2
Pluggable driver architecture using factory pattern
The package creates CAPTCHAs; due to the stateless nature of the HTTP protocol, the logic to secure a webpage using the package must be specifically implemented. See the usage example for detailled information.
Currently, the graphical CAPTCHA driver depends on Image_Text which in turn requires TTF support to be compiled into PHP.
