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).
