AnsiC - ActivateSession|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hi, 

I have skimmed through the .NET sample applications and found that in the session.cs file, the clientSignature is achieved as follows:

// create the client signature.
byte[] dataToSign = Utils.Append(endpoint.ServerCertificate, m_serverNonce);
SignatureData clientSignature = SecurityPolicies.Sign(m_instanceCertificate, endpoint.SecurityPolicyUri, dataToSign);

I wish to perform the same using the AnsiC stack but can’t seem to find a function to assist me with line2 above. 

Has anyone performed this before?

The OPC UA Specification Part4 PAge 50 shows the ActivateSession() function requires a clientSignature in order to activate the session.

Please advise, been stuck with this for a while now.

Thanks 

Sheldon
