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

SYNOPSIS
       signmessage message

DESCRIPTION
       The  signmessage	RPC command creates a digital signature	of message us-
       ing 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	 <https://api.lightning.commu-
	  nity/#grpc-request->.
