KJUR signature

It would help if there was a node for using the KJUR library. We are trying to integrate an API with a RS256 signature, here the line below, N8N does not recongnize

const signedJWT = jwt.sign({ header: jwtHeader, payload: jwtPayload }, privateKey, { algorithm: ‘RS256’ });

My use case:

Any resources to support this?

Are you willing to work on this?
