[Question] Reference implementation of client side Secure connection with the server

[jchirantan]

Hi @kevinherron,

Is there any reference implementation, guide, or at least some tips on how to establish a certificate-based secure connection and username/password-based connection with a server using the Eclipse Milo client?

I searched for it and found that UsernameProvider can be used to establish username/password-based connections and X509IdentityProvider can be used for certificate-based connections.

Is this right?

Also, can you provide some examples or documentation on how to use these APIs correctly for a secure connection?

Thanks,
Chirantan

You've got it right, there's not much to it.

OpcUaClient client =
    OpcUaClient.create(
        "opc.tcp://milo.digitalpetri.com:62541/milo",
        endpoints -> endpoints.stream().findFirst(),
        cfg -> {},
        cfg -> cfg.setIdentityProvider(new UsernameProvider("User", "password")));

client.connect();

DateTime currentTime =
    client.getAddressSpace().getServerNode().getServerStatus().getCurrentTime();

System.out.println("Current time: " + currentTime);

client.disconnect();
