(WHM >> Home >> SSL/TLS >> Install an SSL Certificate on a Domain)
Use this interface to install an SSL certificate on a domain, subdomain, or addon domain. Before you can use this feature, you must create or purchase a certificate, and you must possess the certificate's key.
For more information, read our What is Domain TLS? documentation.
When you install a certificate, this interface indicates whether your certificate is self-signed. Self-signed certificates are easy targets for attackers and generate security warnings in your users’ web browsers. Only install a self-signed certificate temporarily, until you can replace the certificate with a certificate from a valid certificate authority (CA).
Server Name Indication (SNI) allows a server to install multiple certificates to the same IP address.
blog.example.com, use a single wildcard certificate.
Install an SSL certificate
Use either of the methods below to install certificates on your server.
To find and select a certificate on your server, and install it, perform the following steps:
Select an account from the Browse Account menu, or select Browse Apache.
The menu's certificates correspond to the account that you select. This menu does not indicate that the system will install the selected certificate to the selected account.
Click Use Certificate. The system automatically populates the text boxes.
To use the domain name to find and install the certificate, perform the following steps:
Enter your domain in the Domain text box. The Autofill by Domain button will appear.
Enter the certificate's information in the appropriate text boxes, or click Autofill by Domain to automatically populate the certificate information text boxes.
If multiple certificates exist for the same domain, the server attempts to choose the best certificate. In this scenario, to avoid potential issues, use the Browse Certificates method.
