AttestationProofCreator
class AttestationProofCreator(loadKeyAttestation: suspend (OpenId4VciClient.KeyAttestationInput) -> KmmResult<JwsCompactTyped<KeyAttestationJwt>>) : ProofCreator(source)
Creates proofs of the attestation proof type (OpenID4VCI 1.0, Appendix F.3): exactly one key attestation in JWT format (Appendix D.1), loaded with loadKeyAttestation, without a proof of possession of the attested keys. The c_nonce is passed to loadKeyAttestation as KeyAttestationInput.clientNonce, as it has to be the nonce of the key attestation if the issuer has a Nonce Endpoint (Appendix F.3).
Creating the proof fails if loadKeyAttestation fails. Creates no proof if the issuer does not accept the attestation proof type for the requested credential.
