exportClientCertificate

Copy OPC UA client application certificates to file

Syntax

fileName = opc.ua.exportClientCertificate

fileName = opc.ua.exportClientCertificate("SHA1")

fileName = opc.ua.exportClientCertificate("SHA256")

opc.ua.exportClientCertificate("SHA1",FileName)

opc.ua.exportClientCertificate("SHA256",FileName)

Description

fileName = opc.ua.exportClientCertificate copies the OPC Toolbox SHA256 UA Client Application Certificate to the file MATLAB_OPCToolbox_SHA256.der in the user folder. The full path to the file is returned in fileName.

fileName = opc.ua.exportClientCertificate("SHA1") copies the OPC Toolbox SHA1 UA Client Application Certificate to the file MATLAB_OPCToolbox_SHA1.der in the user folder. Note that SHA1 is considered insecure by the OPC Foundation, and this certificate should be used only for backward compatibility. The full path to the file is returned in fileName.

fileName = opc.ua.exportClientCertificate("SHA256") copies the OPC Toolbox SHA256 UA Client Application Certificate to the file MATLAB_OPCToolbox_SHA256.der in the user folder. The full path to the file is returned in fileName.

opc.ua.exportClientCertificate("SHA1",FileName) or opc.ua.exportClientCertificate("SHA256",FileName) copies the corresponding OPC Toolbox UA Client Application Certificate to the file given by FileName. If the full path to FileName does not exist, the function attempts to create it. You can use the generated file to register the Client Application Certificate with any servers that require trusted certificates. The Client Application Certificate is exported in .der format.

Examples

Export Client Certificate
