Then, update your config/app.php by adding new value to the providers and alias key:

    'providers' => array (

        //...

        'Wicochandra\Captcha\CaptchaServiceProvider'
    ),

    //...

    'aliases' => array (

        //...

        'Captcha'         => 'Wicochandra\Captcha\Facade\Captcha',
    ),

Lastly, you need to publish vendor assets

    php artisan vendor:publish

Usage

There are two main usage of the package.

1. Image link, you can use the following directive to generate the captcha link.

    //Will return http://[web url]/captcha/image
    Captcha::url();

1. Validator, you can use captcha validator or Captcha::isValid($value) to validate whether the input is match with the captcha image or not.

   $rules = array(
        '[input name]' => 'captcha'
    );

    Captcha::isValid('captcha-input');  //return true if valid. Otherwise return false

Note: You have to define validation error message for captcha by yourself on resources/lang/{locale}/validation.php
