A secure website builds trust and protects sensitive data. Whether you’ve purchased an SSL certificate from a provider like DigiCert, Comodo, or Namecheap, installing it correctly on your hosting account is crucial.

If you use Sternhost’s reliable web hosting, installing a third-party SSL certificate in cPanel is quick and hassle-free. This guide will show you how to set it up step by step.

Why Install a Third-Party SSL Certificate?

While free SSL solutions like Let’s Encrypt are great for basic encryption, a third-party SSL certificate can offer:

• Extended Validation (EV) for higher trust levels.

• Wildcard Support to secure multiple subdomains.

• Advanced Encryption and stronger warranties.

• If you require business validation or premium features, a third-party SSL is the way to go.

Step-by-Step Guide to Installing a Third-Party SSL in cPanel

1. Purchase and Obtain Your SSL Certificate

• Buy your SSL certificate from a trusted provider (e.g., DigiCert, GeoTrust, Sectigo).

• During purchase, you’ll be asked for a CSR (Certificate Signing Request)—you’ll generate this inside cPanel.

2. Generate a CSR in cPanel

• Log in to your cPanel account from your Sternhost dashboard

• Navigate to Security > SSL/TLS.

• Click Generate, view, or delete SSL certificate signing requests (CSRs).

• Enter your domain details (Common Name, City, Country, etc.).

• Click Generate and copy the CSR provided.

3. Submit the CSR to Your SSL Provider

• Paste the generated CSR into your SSL provider’s order form.

• They’ll validate your domain or organization (depending on the SSL type).

• After verification, you’ll receive certificate files via email (usually a .crt file and CA bundle).

4. Upload the SSL Certificate to cPanel

• Return to cPanel > SSL/TLS.

• Click Install and Manage SSL for your site (HTTPS).

• Select your domain.

• Paste the certificate code (or upload the .crt file).

• Click Install Certificate.

✅ Your third-party SSL is now active!

Verifying the SSL Installation

After installation:

• Visit your site using https://yourdomain.com to confirm.

• Use tools like SSL Checker to ensure everything is set up correctly.

Troubleshooting Tips

• Mismatch Error: Make sure the CSR and certificate were generated for the same domain.

• Intermediate Certificates: Always upload the CA bundle to prevent browser trust issues.

• Propagation Delay: It may take a few minutes for changes to reflect.
