Captcha for Kohana 3.x

This is the Captcha library ported from Kohana 2.3.x to 3.x. Very little has changed API-wise, although there have been a few changes.

Getting Started

Instantiate a captcha:

$captcha = Captcha::instance();

Instantiate using your own config group (other than 'default'):

$captcha = Captcha::instance('myconfig');

Render a captcha:

$captcha->render();

or just:

$captcha;

Validate the captcha:

Captcha::valid($_POST['captcha']);

By default image-based captchas are rendered with HTML, the HTML is a very simple tag. If you want to handle your own rendering of the captcha simply set the first parameter for render() to FALSE:

$captcha->render(FALSE);
