lightning-signmessage – Command to create a signature from this node¶
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.
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.
