We are using Opc.Ua.Core.dll and Opc.Ua.Client.dll ( Version 1.4.354 ) in our application . Our application is targeted to .NET framework 4.6. Basically we have upgraded the OPC foundation SDK from Version 1.3.342 to version 1.04.354.
When we try to communicate our OPC UA client application to any OPC UA server with any security mode ( Basic128Rsa15 , Basic 256 ) We are getting the error message
“SHA1 signed certificates are not trusted” .
It works fine with NONE security .
based on the reference https://github.com/OPCFoundati.....issues/306,
We have added below nodes under ‘SecurityConfiguration’ in our configuration file
But the ApplicationConfiguration.SaveToFile() function removes the node "RejectSHA1SignedCertificates" from the configuration file .
Could you please advice us any solution for this?
