NAME
     signmessage -- Command to create a signature from this node

SYNOPSIS
     signmessage message

DESCRIPTION
     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 (string): Less than 65536 characters long message to  be  signed
	by the node.

RETURN VALUE
     On success, an object is returned, containing:

     *	signature (hex) (always 128 characters): The signature.
     *	recid (hex) (always 2 characters): The recovery id (0, 1, 2 or 3).
     *	zbase  (string):  signature and recid encoded in a style compatible with
	lnd's SignMessageRequest.
