Certificates are used to increase the security of the communication between Device Administrator and automation server.

Certificates are used to establish a trust chain between Device Administrator and the automation servers. A trusted chain communication with HTTPS consists of two parts:

  • An SSL root certificate installed in Windows on the computer that runs Device Administrator

  • An SSL certificate on the automation server

Both Device Administrator and automation servers supports self-signed certificates as well as CA certificates. Device Administrator allows you to create your own self-signed certificate.

Import and export

Certificates can be imported and exported. For example, you have established a trust chain between computer 1, running Device Administrator, and a list of automation servers. You want to access the same automation servers using computer 2. In this case, you install Device Administrator on computer 2, export the SSL root certificate from computer 1, and import it to computer 2.

Backup

The certificates are included in the automation server’s backup. You do not need to generate a new certificate if you restore an automation server from a backup generated after the certificate was transferred to the automation server if you retain the original root certificate.

Certificates and licensing

Certificates generated and installed using Device Administrator must be used when activating licenses.

Certificates generated using Workstation cannot be used for licensing in automation servers since these certificates do not provide a root certificate or other trust chain for validation. If you use WorkStation certificates, we recommend that you generate new ones for your automation servers from Device Administrator when you use licensing in automation servers.
