Managing Digital Certificates

If you set OPCUA security options to "None", connecting with an OPCUA server will require an OPCUA-compliant digital certificate and key pair.

You can generate and use your own self-signed OPCUA compliant digital certificate and key pair. This digital certificate can be associated to the OPCUA Client service to exchange data with any OPCUA compliant server. You can use a variety of third-party utilities to generate and manage digital certificates, if you are familiar with the OPCUA standard and digital certificate management described in this section.

This section uses a set of sample applications from the OPC Foundation to illustrate how to install, configure and generate OPCUA-compliant digital certificates. A self-signed digital certificate is used in this example. The information and procedures in this section are for illustration purposes, and may vary depending upon your applications and utilities.

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.
