Version: 0.6

Plugins Required: None
Plug & Play: Yes
Supported: Yes

Description
The web's most popular anti-spam captcha system. By itself, it doesn't do anything, but other plugins can utilize it.

Instructions
1. Upload the "recaptcha" folder to your plugins folder.
2. Install it from Plugin Management in Admin.
3. To use it, you'll need to register at http://recaptcha.net/, get your keys and put them in Admin -> Plugin Settings -> reCaptcha.

Notes for Plugin Developers
Including reCaptcha in your plugin is quite simple. It uses two plugin hooks:

$h->pluginHook('show_recaptcha'); // this should be wrapped in a form

$result = $h->pluginHook('check_recaptcha'); // check the captcha

switch($result['ReCaptcha_check_recaptcha'])
{
    case 'empty':
        // show error message for an empty captcha
        break;
    case 'error':
        // show error message for an incorrect answer
        break;
    case 'success':
        // captcha completed correctly
        break;
    default:
        // do nothing
} 

For a working example, see /recaptcha/recaptcha_settings.php from approx. line 63.

hmmm... if i am not wrong, i've see reCaptcha at user signin plugins ?

Important!
The User Signin plugin already has reCaptcha, but in the future it will be removed and this plugin will be necessary instead. The reason for that is by making reCaptcha a standalone plugin, any plugin can use it regardless of whether User Signin is installed, and you'll only have to enter your reCaptcha keys once.

To be clear, you do not need this plugin unless another plugin requires you to install it.

It's not just reCaptcha, all the images on your registration page are huge!!! (IE8 with compatibility mode OFF)

Sorry, it's not possible with the current plugins.

I've updated the plugin to version 0.2.0.
You now can customize the language and choose one of the 4 default themes.

Now the only thing missing for this plugin is the custom theming of the reCaptcha widget, maybe this will happen later on when there is need for it.
