#Captcha for Kohana 3.3
This is the Captcha library ported from Kohana 3.0.x to 3.3. Very little has changed API-wise, although there have been a few changes.
One significant change is that filenames are now Title Case to conform with the PSR-0 standard adopted in Kohana 3.3.
##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);
