lightning-checkmessage -- Command to check if a signature is from a node
SYNOPSIS
checkmessage message zbase [pubkey]
DESCRIPTION
The checkmessage RPC command is the counterpart to signmessage: given a node id (pubkey), signature (zbase) and a message, it verifies that the signature was generated by that node for that message (more technically: by someone who knows that node's secret).
As a special case, if pubkey is not specified, we will try every known node key (as per listnodes), and verification succeeds if it matches for any one of them. Note: this is implemented far more efficiently than trying each one, so performance is not a concern.
On failure, an error is returned and core lightning exit with the following error code:
- -32602: Parameter missed or malformed;
- 1301: pubkey not found in the graph.
RETURN VALUE
On success, an object is returned, containing:
- verified (boolean): whether the signature was valid (always true)
- pubkey (pubkey): the pubkey parameter, or the pubkey found by looking for known nodes
