X509 certificate authentication for OPC UA clients

Is there any update since this thread from 2021 on OPC UA X509 certificate authentication?

I am trying to experiment with Rockwell's FT Optix Studio and setup an OPC UA connection to one of our Ignition development servers. FT Optix does not appear to support username/password authentication, and Ignition does not appear to support X509 cert authentication.

Has this been implemented, or is it on the road map?

It hasn’t been, but I can take a look when I’m back next week and see how much work it would be to add. If I remember correctly it’s mostly just awkward because our configuration/settings model is a little too limited right now and I don’t quite know how or where the KeyStore that holds the certificate and private key would be stored and accessed.
