Hello,

That's correct. I am aware of the directory path configuration. My EasyUA version is 5.61.

Thanks, the link you sent helped to find the properties. TrustedPeers, TrustedIssuer and Rejected Certificate stores properties are under CertificateAcceptancePolicy as mentioned in the link as well. However, ApplicationCertificateStore is under ApplicationParameters property that can be reached in this way;

EasyUAClient.SharedParameters.EngineParameters.ApplicationParameters.ApplicationCertificateStore = "...";


Best regards.

Thanks for prompt reply!

OK, I assume I should for example write like the following;

EasyUAClient.SharedParameters.EngineParameters.ApplicationParameters.ApplicationCertificateStore = "C:\\ProgramFiles\\EKD\\OPC Foundation".
Here EKD is the application folder and I want EasyUA client to use the Certiifcates inside OPC Foundation folder in the path above. Inside the OPC Foundation folder I have the following folder structure in place:



Now the question is whether this structure is good enough to give the directory path at the folder "OPC Foundation" level or do we need to give the path to the inner folders; "Machine Default", "UA Applications" and "RejectedCertificates" folders? If the latter is the answer, then I do not have specifics of the certificates in the property in the EasyUAClient.SharedParameters.EngineParameters.ApplicationParameters.ApplicationCertificateStore. Because in the newer version after 2022.2 I see that you can specify each certificates like below;

SharedParameters->EngineParameters->ApplicationParameters->ApplicationManifest->InstanceOwnStorePath = "Machine Default"
SharedParameters->EngineParameters->ApplicationParameters->ApplicationManifest->InstanceTrustedStorePath = "UA Applications"
SharedParameters->EngineParameters->ApplicationParameters->ApplicationManifest->RejectedStorePath = "RejectedCertificates"

So in the ApplicationManifest there are properties InstanceOwnStorePath, InstanceTrustedStorePath and RejectedStorePath that you can specify individually. How could we do the same with earlier versions that we do not have ApplicationManifest?

Best regards.

Hello,

Thanks for your answer.

The version that we have the license for is not 2022.2 version, so it does not exactly have this option as you said but instead, I could find this
EasyUAClient.SharedParameters.EngineParameters.ApplicationParameters.ApplicationCertificateStore = "string".

In the pop-up where it gives a description of the ApplicationCertificateStore says; "The store containing application instance certificate (or where the application instance certificate will be created)." And expects a string type parameter. Is this where we can configure the certificate stores paths in the earlier version than 2022.2 or is this for some other thing?

Best regards.

Hello,

I am using easyOpc client inside a .Net core application. When running the application, EasyOpc client uses the system Directory Certificate Store in Windows even if I have a local folder with the same structure as it should be for Certificate Store contents in my application directory where .exe is located. Is there a way to configure where the directory Certificate Store to be used by the EasyOpc client?

We do not want to use the system folder of Windows (where it is automatically used as directory Certificate Store) and we want to use local application directory where the .exe of the application is located.

Regards.
