Are there any documentations available showing system master-key usages?
So far the docs (i.e. EVM setup) I've seen generates a trusted master
key and then create the encrypted keys from that. I'm missing the
understanding of how to generate encrypted keys from the system master
key initially during setup. Thanks!
