"LocalMachine\" or "CurrentUser\" followed by a store name.The store containing any trusted issuer certificates for application instances.
Typical web browsing applications trust any certificate issued by a CA in the "Trusted Root Certification Authorities" certificate store. However, this approach is not appropriate for UA because Administrators have no control over the CAs that get placed in that Root store to facilitate web browsing. This means Administrators must specify a different store that is used only for UA related CAs and/or they must explicitly specify the certificate for each trusted certification authority.
In order to obtain or modify this parameter for server instance certificates, access the OpcLabs.EasyOpc.UA.Engine.UAClientServerApplicationParameters.ApplicationManifest property of OpcLabs.EasyOpc.UA.Application.EasyUAApplicationCore.ApplicationParameters property of static EasyUAApplication.Instance.
// This example demonstrates how to configure the location of the certificate stores to directories specified by absolute // paths. // Obtain the application interface. $Application = new COM("OpcLabs.EasyOpc.UA.Application.EasyUAApplication"); // Set the application certificate store paths. // Note that this only works once in each host process. // If this code is used in a Web application, make sure it is executed at the beginning of every page that can be used to // enter your application. You will most likely make it into a subroutine then. $Application->ApplicationParameters->ApplicationManifest->InstanceIssuerStorePath = "C:\\MyCertificateStores\\UA Certificate Authorities"; $Application->ApplicationParameters->ApplicationManifest->InstanceOwnStorePath = "C:\\MyCertificateStores\\Machine Default"; $Application->ApplicationParameters->ApplicationManifest->InstanceTrustedStorePath = "C:\\MyCertificateStores\\UA Applications"; $Application->ApplicationParameters->ApplicationManifest->RejectedStorePath = "C:\\MyCertificateStores\\RejectedCertificates"; // Do something - invoke an OPC read, to trigger creation of the certificate. $Client = new COM("OpcLabs.EasyOpc.UA.EasyUAClient"); try { $value = $Client->ReadValue( //"http://opcua.demo-this.com:51211/UA/SampleServer", "opc.tcp://opcua.demo-this.com:51210/UA/SampleServer", "nsu=http://test.org/UA/Data/ ;i=10853"); } catch (com_exception $e) { printf("*** Failure: %s\n", $e->getMessage()); } printf("Finished.\n");
