Use the Self-Signed OPC UA Compliant Certificate and Key Pair

To use the self-signed OPC UA Compliant Certificate and Key Pair

1. Install the UA Client on every computer on which you want to deploy the UA Client service instance.

2. Create the UA Client service configuration.

3. Copy the certificate file aaUAClient.der from C:\Tmp\TestUACert\certs directory into the path %CommonApplicationData%\ArchestrA\CertificateStores\OPCUAClient\certs, on every computer on which you want to deploy the UA Client service instance.

   By doing this, you have replaced the file with same name in that directory.

   NOTE: The path to store program data is %CommonApplicationData%. By default, this location is C:\ProgramData\.

4. Copy the private key file aaUAClient.pfx from C:\Tmp\TestUACert\private directory into the path %CommonApplicationData%\ ArchestrA\CertificateStores\OPCUAClient \private, on every computer on which you want to deploy the UA Client service instance.

   By doing this, you have replaced the file with the same name in that directory.

   NOTE: The path to store program data is %CommonApplicationData%. By default this location is C:\ProgramData\.

5. On the computer where the targeted OPC UA Server may be running, copy the certificate file aaUAClient.der from C:\Tmp\TestUACert\certs directory into the directory where you want to add the trusted cert for the OPC UA Server.

6. Deploy the UA Client service instance to the node.
