lightning-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* must be less that 65536 characters.
RETURN VALUE
------------
An object with attributes *signature*, *recid* and *zbase* is
returned. *zbase* is the result of *signature* and *recid* encoded in
a style compatible with **lnd**'s [SignMessageRequest](https://api.lightning.community/#grpc-request-signmessagerequest).
