Example

If you have generated an encrypted private key using the 'Keypair Property Dialog', for example, you can use the following code to set the password. Otherwise, you will receive an error message.

Copy Code

procedure TForm1.Button1Click(Sender: TObject);
begin
  dOPCUAClient1.URL :=  'opc.tcp://localhost:53530/OPCUA/SimulationServer';
  dOPCUAClient1.SecurityKeypair.Password := 'test';
  dOPCUAClient1.Active := true;
end;
