Title: Implementing CAPTCHA in Laravel 6

Introduction:

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security mechanism used to prevent automated bots from submitting forms on websites. It presents a challenge that only humans can typically solve, like recognizing distorted characters or selecting specific images from a set. In this tutorial, we will demonstrate how to implement CAPTCHA in Laravel 6 using a popular package called "greggilbert/recaptcha."

Step 1: Install Laravel 6 and Set Up a New Project

Before we proceed, make sure you have Laravel 6 installed on your system. If not, you can create a new Laravel 6 project using Composer by running the following command:

```bash

composer create-project --prefer-dist laravel/laravel project-name "6."

```

Step 2: Obtain reCAPTCHA API Keys

To use the reCAPTCHA service, you need to obtain API keys. Visit the reCAPTCHA website (https://www.google.com/recaptcha) and create a new site. You'll receive a site key and a secret key; keep these handy as we'll use them in the next steps.

Step 3: Install the "greggilbert/recaptcha" Package

In your Laravel 6 project, open the terminal and navigate to the project's root directory. Then, use Composer to install the "greggilbert/recaptcha" package:

```bash

composer require greggilbert/recaptcha

```

Step 4: Configure the Package

After installing the package, open the `config/app.php` file and add the following lines to the `providers` array:

```php

'providers' => [

// Other providers...

Greggilbert\Recaptcha\RecaptchaServiceProvider::class,

],

```

Next, add the following lines to the `aliases` array in the same file:

```php

'aliases' => [

// Other aliases...

'Recaptcha' => Greggilbert\Recaptcha\Facades\Recaptcha::class,

],

```

Step 5: Set Up reCAPTCHA API Keys

In the `.env` file, add the following lines and replace `YOUR_RECAPTCHA_SITE_KEY` and `YOUR_RECAPTCHA_SECRET_KEY` with the keys you obtained in Step 2:

```dotenv

RECAPTCHA_SITE_KEY=YOUR_RECAPTCHA_SITE_KEY

RECAPTCHA_SECRET_KEY=YOUR_RECAPTCHA_SECRET_KEY

```

Step 6: Add CAPTCHA to Your Form

Assuming you have a form in your Laravel 6 application that you want to protect with CAPTCHA, open the corresponding Blade view file and add the following code where you want the CAPTCHA to appear:

```html

```

Step 7: Validate CAPTCHA in the Controller

Now, let's validate the CAPTCHA in the controller before processing the form submission. In your controller's method, you can add the following code:

```php

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Validator;

public function submitForm(Request $request)

{

$validator = Validator::make($request->all(), [

// Your other validation rules here...

'g-recaptcha-response' => 'required|recaptcha',

]);

if ($validator->fails()) {

return redirect()->back()->withErrors($validator)->withInput();

}

// Process the form submission here...

return redirect()->back()->with('success', 'Form submitted successfully!');

}

```

Conclusion:

By following these steps, you have successfully implemented CAPTCHA in your Laravel 6 application using the "greggilbert/recaptcha" package. This will help protect your forms from automated bot submissions and enhance the security of your web application.
