External signature service

[dariocast]

I noticed pymdoccbor supports HSM-based signing (though the process isn’t entirely clear).
Is it possible to use an external signing service instead—just to generate the signature—and then append that signature to the CBOR object?

it is technically possibile

it must be implemented

it could became a plugin system where implementers could be able to register their own pluign (external package) and the current crypto approach (local keys) could be moved to a plugin, the default one
