   aemp setsecret <secret>     # set the shared secret
   aemp clrsecret              # remove the secret

   # node configuration: TLS
   aemp setcert <file>         # set a certificate (key.pem + certificate.pem)
   aemp clrcert                # remove certificate
   aemp gencert                # generate a random certificate

   # node configuration
   aemp setseeds noderef...    # set seednodes
   aemp addseed noderef        # add a seednode
   aemp delseed noderef        # remove seednode
