Installing an SSL certificate protects your website by enabling HTTPS encryption, which secures your visitors’ data and builds trust. If you’re using hosting that supports cPanel (like Nextel Systems), the process is simple — especially with free SSL from Let’s Encrypt.

Method 1: Installing a Free SSL Certificate (Let’s Encrypt or AutoSSL)

Most modern hosting providers include AutoSSL or Let’s Encrypt built into cPanel.

🔹 Step-by-Step Guide:

1. Log in to cPanel
   • Visit yourdomain.com/cpanel
   • Enter your hosting username and password.
2. Locate the SSL/TLS or “Let’s Encrypt” Tool
   • Scroll to the Security section.
   • Click on SSL/TLS or Let’s Encrypt SSL (depending on your host).
3. Choose the Domain
   • Select the domain where you want to install the SSL.
   • Click Issue or Install next to it.
4. Confirm Settings
   • Use default settings unless you need to install for subdomains or aliases.
   • Click Install Certificate or Submit.
5. Wait for Confirmation
   • After a few seconds, you’ll see a success message confirming the SSL has been installed.
6. Force HTTPS (Optional but Recommended)
   • Go to the .htaccess file in File Manager (public_html) and add:

     RewriteEngine On
     RewriteCond %{HTTPS} off
     RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
     

   • Or, use the “Force HTTPS Redirect” option in cPanel if available.

Method 2: Installing a Paid SSL Certificate Manually

If you’ve purchased an SSL from another provider:

1. Go to cPanel > SSL/TLS.
2. Click “Manage SSL Sites” under “Install and Manage SSL”.
3. Paste the CRT (Certificate), Private Key, and CA Bundle.
4. Click Install Certificate.

How to Verify SSL Is Active

• Visit your site using https://yourdomain.com
• Look for the padlock icon in the browser.
• Use tools like SSL Checker to confirm everything is configured correctly.

Tips on How to install an SSL certificate

• SSL certificates usually auto-renew (especially Let’s Encrypt).
• For WordPress sites, update the WordPress Address and Site URL under Settings > General to use https://.
• Consider using a plugin like Really Simple SSL to make the transition easier.
