\#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);

\##Captcha Styles

- alpha
- basic
- black
- math
- riddle
- word
