The web's most popular anti-spam captcha system. By itself, it doesn't do anything, but other plugins can utilize it.
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:
For a working example, see /recaptcha/recaptcha_settings.php from approx. line 63.
$h->pluginHook('show_recaptcha'); // this should be wrapped in a form
$result = $h->pluginHook('check_recaptcha'); // check the captcha
// show error message for an empty captcha
// show error message for an incorrect answer
// captcha completed correctly
// do nothing
