Support for ES256 signature

[blackarcanis]

Hi,
Seems useful to support ES256, Apple require it for Apple Music API

Still nothing?

If you want to sign Apple's JWT on iOS/macOS, you could also try CupertinoJWT, which was pre-released recently. I've wrote it because I couldn't find a solution for creating JWT used for Apple's server APIs on iOS/macOS.

This project is seemingly no longer being maintained by its owner, but IBM’s Swift-JWT supports ES256 signing and verifying on Apple platforms and Linux, and it is an excellent replacement in my experience.

ETA: I’ve used Swift-JWT to connect to APNS, so it should also work for Apple Music.
