Replied by support on topic Specifying security policy
A. Selection of Specific Endpoint

QuickOPC (currently) does not allow you to specify precisely the endpoint parameters. Instead, it uses a negotiation algorithm, and a so-called endpoint selection policy, to choose the parameters of the communication.

The closest you get is probably as follows:

var client = new EasyUAClient
{
    Isolated = true,
    IsolatedParameters =
    {
        Session = 
        { 
             EndpointSelectionPolicy =
             {
                AllowedMessageSecurityModes = UAMessageSecurityModes.SecuritySignAndEncrypt, 
                MessageSecurityPreference = Sign.Positive
             } 
        }
    }
};

This takes care of the Sign&Encrypt part, but does not enforce the Basic256 part.


B. Specifying User name and Password

This is easy. Example code:

var client = new EasyUAClient
{
     Isolated = true,
     IsolatedParameters = 
     { 
         Session = { UserIdentity = { UserNameToken = { UserName = "usr", Password = "pwd" }}}
     }
};
Best regards

Subject: OPC Labs Contact Form - EasyOpc.UA

Hello

I am evaluating EasyOpc.UA. I would like to connect to an OPC UA server with Security policy = Basic256, Message Security mode = Sign & Encrypt and a username/password.

I was unable to find any documentation on how to configure the EasyUAClient to connect with the mentioned security policy. Nothing in the forums either.

Could you please provide some sample code in C# ?

Quick reply appreciated.

Thanks.
