They're a little subtle, so let's spell out exactly what checkmessage means. In particular, we avoid discussing key derivation from a signature, as it tends to get people (like me!) into trouble: we describe it instead as iterating through every known node.

.SH NAME
|
|
lightning-signmessage - Command to create a signature from this node
|
|
.SH SYNOPSIS
|
|
|
|
\fBsignmessage\fR \fImessage\fR
|
|
|
|
.SH DESCRIPTION
|
|
|
|
The \fBsignmessage\fR RPC command creates a digital signature of
|
|
\fImessage\fR using this node's secret key\. A receiver who knows your
|
|
node's \fIid\fR and the \fImessage\fR can be sure that the resulting signature could
|
|
only be created by something with access to this node's secret key\.
|
|
|
|
|
|
\fImessage\fR must be less that 65536 characters\.
|
|
|
|
.SH RETURN VALUE
|
|
|
|
An object with attributes \fIsignature\fR, \fIrecid\fR and \fIzbase\fR is
|
|
returned\. \fIzbase\fR is the result of \fIsignature\fR and \fIrecid\fR encoded in
|
|
a style compatible with \fBlnd\fR's \fBSignMessageRequest\fR (\fIhttps://api.lightning.community/#grpc-request-signmessagerequest\fR)\.
