SdJwt.Net.Oid4Vci - OpenID for Verifiable Credential Issuance

NuGet Version License

Implementation of OpenID4VCI 1.0 models and helpers for standardized credential issuance flows.

Features

  • OID4VCI 1.0 Models: Offer, token, request, and response payloads
  • Grant Flow Support: Authorization Code and Pre-Authorized Code patterns
  • Proof Support: Single-proof and multi-proof request models
  • Transport-Agnostic Design: Works with ASP.NET Core, worker services, and custom gateways
  • Deferred Issuance Support: Acceptance-token response model support

Installation

dotnet add package SdJwt.Net.Oid4Vci

Quick Start

Build a Credential Offer

using SdJwt.Net.Oid4Vci.Models;
using System.Text.Json;

var credentialOffer = new CredentialOffer
{
    CredentialIssuer = "https://issuer.example.com",
    CredentialConfigurationIds = new[] { "university_degree" }
};

credentialOffer.AddPreAuthorizedCodeGrant(
    preAuthorizedCode: "pre-auth-code-123");

var qrUrl =
    $"openid-credential-offer://?credential_offer={Uri.EscapeDataString(JsonSerializer.Serialize(credentialOffer))}";

Build a Credential Request

using SdJwt.Net.Oid4Vci.Models;

var credentialRequest = CredentialRequest.Create(
    vct: "https://issuer.example.com/credentials/university-degree",
    proofJwt: holderProofJwt);

credentialRequest.Validate();

Build a Credential Response

using SdJwt.Net.Oid4Vci.Models;

var credentialResponse = CredentialResponse.Success(
    credential: issuedCredential,
    format: Oid4VciConstants.SdJwtVcFormat);

Common Use Cases

  • University issuance with pre-authorized codes
  • Government onboarding with OAuth authorization code flow
  • Enterprise onboarding with batch and deferred issuance
  • Wallet interoperability through standard OpenID4VCI payloads
