Supporting MacOS and Linux for the client tool would be nice.
Supporting Linux for the server is doable, for the client that would take a lot of work as we currently use the same windows api’s that signtool uses for writing the signature etc into the exe.
We have the server running on Linux - I have it running here on a raspberry pi - however not all tokens have linux arm pkcs#11 drivers.
We still have solve the packaging/installation of the server on linux before we can release it.
