How to Install an SSL Certificates

SSL Certificates are text files with encrypted data that you install on your server so that you can secure/encrypt sensitive communications between your site and your customers.

After you create a CSR (certificate signing request) and purchase a certificate, our Validation team validates and processes your certificate request. Once validated, we issue your SSL Certificate and send it to you via email. You can also download your SSL Certificate in your DigiCert account.

After you’ve installed your SSL Certificate, we recommend that you make a backup copy of the certificate and store it in a secure place. If a server crashes or needs to be replaced, it is much easier to secure the replacement server.

When downloading your SSL Certificate from your account, you will need to download an intermediate certificate. Browsers require the intermediate certificate to complete the certificate trust chain. The intermediate certificate links your SSL Certificate to DigiCert’s root certificate. Registered Certificate Authorities such as DigiCert must provide a known root certificate before their SSL Certificate can be trusted by SSL-enabled applications (learn more about the role of intermediate and root certificates). Note that for some servers (such as Microsoft) the intermediate certificates are bundled with the SSL Certificate.

Once you have your certificate installed, we recommend that you check that everything is working correctly using our free SSL Installation Diagnostics Tool. Alternatively, for an easy way to find and manage all the certificates on your network, try our free DigiCert Certificate Inspector tool.
