Understanding Certificate Management

SSL certificates are used for encrypted communication between the CDN and clients. 

To add an SSL certificate to your site, upload a certificate that you own, associate it with the site, and then publish the site.

Only one certificate may be associated with a site. If multiple hostnames are configured, ensure that the certificate includes all the hostnames.

Note: Your QC User is associated with an organization. When you or any other user within your organization uploads a certificate, it is added to a shared pool of certificates available to all members of your organization for associating with a site. 

Supported Actions

Certificate Management supports the following actions:

• Upload a Certificate - The Upload feature in the QC Services UI uploads the certificate and automatically associates it with the site. So if a certificate is already associated with the site, first unlink it, and then upload the new certificate. Otherwise, the Upload will fail.
  If your site is already published, republish the site to activate the new certificate.
  
  
• Update a Certificate - Update the certificate associated with a site.
  
  
• Associate a Certificate - Associate an uploaded certificate with a site.
  Only one certificate can be associated with a site. If another certificate is already associated with the site, first unlink it.
  
  
• Unlink a Certificate - Unlinks a certificate from a site.
  
  
• Republish the Site - After updating, associating, or unlinking a certificate for a live site, it is necessary to republish the site to activate the changes.

Although a certificate is automatically associated with the site when it is uploaded via the QC Services user interface, uploading and associating are two distinct processes. If the certificate is ever unlinked from the site, the certificate is not invalidated, and the certificate remains in your organization's pool of certificates that are available for associating with a site.
