Subject: Key Manager - keypair, keyring: -- consistent naming of methods --
 error propagation -- no panic - keyManager: persist, import, export,
 initialize and (re)set keyring - no global public "singleton" keyring,
 instead interface via keyManager - keys test - KeyStore interface, DB and
 File store implementations
