Digital Certificates

You can generate and use a self-signed OPC UA compliant digital certificate and a key pair. This digital certificate can be associated to the UA Client service for exchange data with any OPC UA compliant server.

The UA Configuration utility is used for illustration purpose in this chapter. You can also use other means to generate and manage the digital certificate, if you are familiar with the OPC UA standard and digital certificate management. A self-signed digital certificate is used in this example.

NOTE: In a secured environment where the digital certificate is required to be signed by a Certificate Authority, please consult your IT department for the procedure.
