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
  • Format Metadata: Typed configuration models for dc+sd-jwt, mso_mdoc, jwt_vc_json, jwt_vc_json-ld, and ldp_vc
  • Request/Response Encryption Metadata: Issuer metadata for credential request and response encryption capabilities
  • 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();

using SdJwt.Net.Oid4Vci.Models;
using SdJwt.Net.Oid4Vci.Models.Formats;

var metadata = new CredentialIssuerMetadata
{
    CredentialIssuer = "https://issuer.example.com",
    CredentialConfigurationsSupported = new Dictionary<string, CredentialConfiguration>
    {
        ["employee_sd_jwt"] = new SdJwtVcCredentialConfiguration
        {
            Vct = "https://issuer.example.com/credentials/employee"
        },
        ["employee_jwt_vc_json_ld"] = new JwtVcJsonLdCredentialConfiguration
        {
            CredentialDefinition = new JwtVcJsonLdCredentialDefinition
            {
                Context = new[] { "https://www.w3.org/ns/credentials/v2" },
                Type = new[] { "VerifiableCredential", "EmployeeCredential" }
            }
        }
    }
};

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 for SD-JWT VC, W3C VCDM, and ISO mdoc formats

Test Notes

The test projects target net10.0. On Windows worktrees with restrictive inherited ACLs, use a serialized test run to avoid MSBuild worker buildup:

$env:MSBUILDDISABLENODEREUSE = "1"
dotnet test tests/SdJwt.Net.Oid4Vci.Tests/SdJwt.Net.Oid4Vci.Tests.csproj -f net10.0 -m:1 -nr:false -p:UseSharedCompilation=false
