signmessage returns 65-byte signature in unknown format

See original GitHub issue

Issue Description

Summary When using signmessage a 65-byte (130-hex digits) signature is returned but #1496 says it should be 64 bytes.

Expected behavior signmessage returns 64-byte signature

Actual behavior

signmessage returned 65-byte signature, seems to be prefixed by constant 1f It also seems to be in some undocumented format since it can not be verified by libsecp256k1 (I’m using the Rust crate). Is the hash algorithm sha256?

Steps to reproduce

use signmessage API with any message
observe the sigature field of returned Json Eclair version: 0.6.2

Environment

Linux, ARM64 openjdk 11.0.9

Gotcha, if you think documenting the code isn’t very important let’s skip it. I’ll update the API doc next time I change it (I tend to batch updates to the API doc and test APIs before I publish), it’s been added to my todo-list.
