public class OID4VCSubjectIdMapper
extends OID4VCMapper

Sets an ID for the credential subject, either from User ID or by attribute mapping

A Verifiable Credential (VC) is often bound to a Holder's Digital Identity (DID). The Holder's DID is in turn bound to Key Material that the Issuer + Verifier can discover from the DID Document. In case of "did:key:..." the Public Key is already encoded in the DID.

Here, we make sure that the default UserProfile has a 'did' attribute when --feature=oid4vc-vci is enabled. Conceptually, it is however debatable whether the Issuer should know even one of the Holder's DIDs

In future, it may be possible that ...

* The Holder communicates the DID at the time of Authorization * The Issuer then verifies Holder possession of the associated Key Material * The Issuer then somehow associates the AuthorizationRequest with a registered User * The VC is then issued to the Holder without the Issuer needing to remember that Holder DID

This kind of Authorization protocol is for example required by EBSI, which we aim to become compatible with. https:*hub.ebsi.eu/conformance/build-solutions/issue-to-holder-functional-flows

Note, that current EBSI Compatibility Tests use the Holder's DID as OIDC client_id in the AuthorizationRequest. That is something we need to work with, but I don't think we should model it like that in our realm config.

Here the attribute definition that we add by default (when not defined already)

{ "name": "did", "displayName": "DID", "permissions": { "view": ["admin", "user"], "edit": ["admin", "user"] }, "validations": { "pattern": { "pattern": "^did:.+:.+$", "error-message": "Value must start with 'did:scheme:'" } } }
