Once your certificate is issued you will receive the certificate (CRT) and the CA bundle (intermediate certificates). Follow these steps to install it on your cPanel hosting.
Steps
- Log in to cPanel and open Security → SSL/TLS.
- Under Install and Manage SSL for your site (HTTPS), click Manage SSL sites.
- Select your domain from the Domain drop-down.
- Paste the contents of your certificate (the
.crtfile for your domain) into Certificate (CRT), including the-----BEGIN CERTIFICATE-----and-----END CERTIFICATE-----lines. - Click Autofill by Certificate. cPanel automatically finds the matching private key (created with your CSR) and usually the CA bundle.
- If the Certificate Authority Bundle (CABUNDLE) box is empty, paste the CA bundle / intermediate certificates you received.
- Click Install Certificate.
Check the installation
- Open
https://yourdomain.comand check the padlock in the address bar. - Use an online SSL checker (for example SSL Labs) to confirm the full chain is installed.

If cPanel says the private key is missing, the CSR was probably generated elsewhere. Generate a new CSR in cPanel and request a free reissue from the configuration page, or open a ticket and we will help.
Note: AutoSSL (free SSL) may already be active on your domain. Installing a paid certificate replaces it automatically; AutoSSL will not overwrite a valid paid certificate.
