Gaia-X support

[dotChris90]

Currently Walt-ID seems to be not sync with Gaia-X GXDCH

I was trying happily Walt.ID CLI tools again and noticed that there is maybe could be a chance that Walt-ID is able to generate VC SD JWT for me which are accepted (compliant) by the Gaia-X GXDCH.

First of all - the converting feature of the CLI is pretty handy and useful. thanks for that. We could e.g. convert a private key in PEM format into jwk format.

next we wanted to take the payload of example from https://compliance.lab.gaia-x.eu/development/docs/#/conformity/CredentialOfferController_verifyBasicConformityLevel (if convert jwt into human readable form - be careful the " at end and begin does not belong to the jwt) and then sign it with Walt-ID CLI.

The process of sign and all works fine seems - so far so good. but the compliance apis does not accept it because they expect header have more informations like issuer. the example payload have headers of the form
{
"alg": "ES256",
"typ": "vc+ld+json+jwt",
"cty": "vc+ld+json",
"iss": "did:web:gaia-x.unicorn-home.com",
"kid": "did:web:gaia-x.unicorn-home.com#X509-JWK2020"
}

So there are several questions related to the relationship between Gaia-X, Aster-X and Walt-ID :

• is there a sync between Gaia-x / aster-X and Walt-ID? since i know for Demos Walt-ID is their prefered solution in past
• if there is no sync : do you care Gaia-X compliance in general? I mean at least it's at least a EU try to shape the future of identity so ....
• is it possible to add fields in the header of jwt or is the header truly fixed? i saw that the issuer is written in the payload of the Walt-ID jwt
• will the Rest-APIs and SDKs result in the same format of jwt?

Thanks for your time and great work until now but i am wondering if there will be some cooperation with Gaia-x ...
