Exporting the certificate with its private key ( Niagara 4.9)

If you are using Niagara 4.9 you may export the display certificate with its private key. This provides the most robust security for data communication.
Prerequisites: You are using Niagara 4.9 or earlier. You are working in Workbench running on a PC. You are connected to the station that manages the display device.
If you are using Niagara 4.10 or later you do not need to export the certificate with its private key. You can use the .pem file you exported to configure the UserService. OpenSSL does not support .pem files and private keys exported from Niagara 4.10.
 
NOTE: The private key of the server certificate validates the public key presented to the display by the client station. A server certificate without a private key is less secure than one with its private key. Without the encryption of the private key, a malicious user could install the certificate into devices that should not be allowed to make a connection. However, when a PIN is involved, as it is with arming and disarming an intrusion zone, the risk is low.
 

Perform the following steps:
  1. To export the certificate with its private key, expand Config > Services > PlatformServices; double-click CertManagerService; in the User Key Store, select the certificate you created and click Export.
    The Certificate Export window opens.

  2. Enable Export the private key, create and confirm a strong password to protect the key, record the password in a safe location and click OK.
    A File Chooser window opens.
  3. Save the file in a location other than the location you used for the first save, for example, C:\certs.
    Since you will use an OpenSSL command prompt to convert the .pem file to a .p12 file, a short path will make it easier to enter the commands.
The next procedure downloads OpenSSL to create a .p12 certificate.
