If you bought an SSL certificate from a certificate authority, you need to install it on your domain in cPanel. This guide walks through adding the certificate, key, and CA bundle.
What you will need #
- The issued certificate (CRT).
- The private key created with your CSR.
- The CA bundle (intermediate certificates).
Installing the certificate #
- Log in to cPanel.
- In the Security section, open SSL/TLS, then Manage SSL sites.
- Select the domain.
- Paste the certificate, the private key, and the CA bundle into their fields.
- Click Install Certificate.
After installing #
- Visit your site with https and check for the padlock.
- Use an online SSL checker to confirm the chain is complete.
- Force HTTPS so all visitors use the secure version.
Do not skip the CA bundle #
Leaving out the CA bundle is a common mistake that causes trust warnings on some devices even though the certificate is valid. Always include the intermediate certificates your provider supplies.
Troubleshooting #
- Key mismatch: the certificate and key must be a matching pair from the same CSR.
- Trust warning: add or correct the CA bundle.
