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 (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.community/#grpc-request- signmessagerequest).
