The signmessage RPC command creates a digital signature of
message using this node's secret key. A receiver who knows your
node's id and the message can be sure that the resulting signature could
only be created by something with access to this node's secret key.
message must be less that 65536 characters.
On success, an object is returned, containing:
- signature (hex): The signature (always 128 characters)
- recid (hex): The recovery id (0, 1, 2 or 3) (always 2 characters)
- zbase (string): signature and recid encoded in a style compatible with lnd's SignMessageRequest
