ECDH-ES (X25519) supported?

[awoie]

Does the jose package has support for ECDH-ES (X25519)? In the documentation you mention you have implemented RFC8037.

The readme explicitly says CFRG Elliptic Curve Signatures (EdDSA) from RFC8037 are implemented

The detailed matrix says

Pending Node.js Support 🤞:

• ECDH-ES with X25519 and X448 - see crypto: X25519 and X448 and ECDH nodejs/node#26626

When Node.js supports it, its going to be supported by jose too. Please go to that issue and voice your interest in the feature.

@awoie i've refactored and with ^1.16.0 there's the option to install a plugin that adds x25519 ECDH-ES support.

also one for the chacha individual draft

That is very helpful! We will try it out!

^1.23.0 now supports ECDH-ES for X25519 and X448 without any plugins when Node.js runtime with the new and improved crypto.diffieHellman interface is detected.
