CGI::Application::Plugin::CAPTCHA allows programmers to easily add and
verify CAPTCHAs in their CGI::Application-derived web applications.
A CAPTCHA (or Completely Automated Public Turing Test to Tell Computers
and Humans Apart) is an image with a random string of characters.  A user
must successfully enter the random string in order to submit a form. This
is a simple (yet annoying) procedure for humans to complete, but one that is
significantly more difficult for a form-stuffing script to complete without
having to integrate some sort of OCR.
CAPTCHAs are not a perfect solution.  Any skilled, diligent cracker will
eventually be able to bypass a CAPTCHA, but it should be able to shut down
your average script-kiddie.
When a CAPTCHA is created with this module, raw image data is transmitted
from your web application to the client browser. A cookie containing a
checksum is also transmitted with the image. When the client submits their
form for processing (along with their verification of the random string),
captcha_verify() generates a checksum of the verification string the user
entered. If the newly generated checksum matches the checksum found in the
cookie, the CAPTCHA is assumed to have been successfully entered, and the
user is allowed to continue processing their form.
