Thanks, but I am sorry, we cannot accept the changes. You don't seem to understand the issue. The code is implementing an international standard. You are not free to choose the used algorithms, since these are defined in the standard. The fact that they are not recommended is reflected to the security policies that use these algorithm being deprecated in the standard. But, we cannot remove or change the implementation, since interoperability with systems that still use them requires them.

Thanks @jouniaro for your input. I believe we should mark these issues as exceptions in our scan directory for now, as they align with the OPC UA standard. Additionally, making unilateral changes could potentially affect communication with the endpoint.
