AccessOPCUA: The OPC UA Server does not use the correct SignatureAlgorithm for the endpoint selected by the OPC UA client
Summary
Communication cannot be established between a specific OPC UA client and the AccessOPCUA Process Gateway, when the client uses Basic256Sha256 with sign, and a UserNameIdentityToken with a specific encryption algorithm for authentication.
Description
Communication between the AccessOPCUA Server and a specific OPC UA Client using Basic256Sha256 with "Sign" and a UserIdentityToken with the rsa-oaep algorithm, could not be established. The algorithm requested by the OPC UA client does not match the signature algorithm and servernonce used by the OPC UA Server.
This behavior has been changed. The AccessOPCUA Server now supports and uses the correct signature algorithm requested by the OPC UA Client.
To take advantage of this fix:
- Update to the latest build of zenon 8.20 or 10.
