IconCaptcha is a security measure that uses icons instead of text to verify human users. In this tutorial, we will guide you through the steps of installing IconCaptcha on Alpine Linux Latest.
Before we begin, make sure you have the following:
The first step is to download the IconCaptcha package from Github. We will use Composer to install the package. Open your terminal and run the following command:
composer require fabianwennink/iconcaptcha
This will download the current version of IconCaptcha and its dependencies to your project directory.
Next, you need to configure your web server to serve the files. Here, we will demonstrate how to configure Nginx.
Open your Nginx configuration file:
sudo nano /etc/nginx/conf.d/default.conf
Add the following lines under the server section:
location /iconcaptcha {
alias /path/to/icons;
}
Make sure to replace /path/to/icons with the path to your IconCaptcha icons directory.
Save the file and exit the editor.
Once you have configured your web server, you can include IconCaptcha in your PHP code.
In your PHP file, add the following code to start a session and load the IconCaptcha library:
session_start();
require_once __DIR__ . '/vendor/autoload.php';
use IconCaptcha\IconCaptcha;
$iconCaptcha = new IconCaptcha();
Lastly, you need to add IconCaptcha to your form. This is done by generating the HTML code for the captcha field and its icons.
Add the following code to your form HTML:
<?php echo $iconCaptcha->html(); ?>
In this tutorial, we have shown you how to install IconCaptcha on Alpine Linux Latest. By following these steps, you have added an additional layer of security to your web server.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
