I have my cryptographic keys and certificates made available via a custom REST service (the private keys don't actually export, they can just do cryptographic operations using the private keys behind the REST service and the result is returned).
I want these objects to show up in my macos keychain and I want to be able to use those objects to sign data.
My understanding is I need to create a cryptotokenkit implementation to do this. However, I see that the only way to load such an implementation is when a card is physically inserted into the machine.
Is there a way to load such a token without needing a physical device inserted into the computer?
