Joomla 2.5 captcha component and plugin

Русская версия

The captcha iself helps to prevent sending forms by robots.

Our component (com_idcaptcha) and plugin (plg_idcaptcha) work together. Component com_idcaptcha generates a picture and places its encrypted code into the session variable. Plugin plg_idcaptcha is designed to integrate the captcha into all forms using the class JForm and provide a verification of the captcha.

The plugin and the component will be used automatically in all forms where there is a captcha type field.
