Add methods to NodeAPI for signmessage and checkmessage #109

Closed dangeross closed 1 year ago

dangeross commented 1 year ago

It would be great if the NodeAPI could expose methods to perform signmessage and checkmessage on the Greenlight node.

Even though I originally asked about this because of LNURL-auth, I think there are still several other use cases where it would be nice to at least sign a message, so that a 3rd party service can verify you are in control of the node. A rough example would be embedding a 3rd party web service (like an exchange) into an application using WebLN.

FYI the endpoints are disabled. I've tried signing the mesage in a variety of ways, but all result in the wrong pubkey. I've posted about this in the greenlight chat. Let's see what comes next week.
