SdJwt.Net.Vc - Verifiable Credentials

NuGet Version License

Implementation of SD-JWT-based Verifiable Credentials aligned with draft-ietf-oauth-sd-jwt-vc-15. Provides strongly-typed models and comprehensive validation for verifiable credentials using the SD-JWT format.

Features

  • Draft 15 Alignment: Core SD-JWT VC issuance and verification with draft-15 updates
  • Type Safety: Strongly-typed models for all VC components
  • Media Type Support: Support for both dc+sd-jwt and legacy vc+sd-jwt media types
  • Status Integration: Built-in support for status claims and revocation checking
  • VCT Validation: Collision-Resistant Name validation for VCT claims

Installation

dotnet add package SdJwt.Net.Vc

Quick Start

Issue a Verifiable Credential

using SdJwt.Net.Vc.Issuer;

var vcIssuer = new SdJwtVcIssuer(issuerKey, SecurityAlgorithms.EcdsaSha256);

var vcPayload = new SdJwtVcPayload
{
    Issuer = "https://university.example.edu",
    Subject = "did:example:student123",
    IssuedAt = DateTimeOffset.UtcNow.ToUnixTimeSeconds(),
    ExpiresAt = DateTimeOffset.UtcNow.AddYears(4).ToUnixTimeSeconds(),
    AdditionalData = new Dictionary<string, object>
    {
        ["degree"] = "Bachelor of Science",
        ["major"] = "Computer Science",
        ["gpa"] = 3.8,
        ["graduation_date"] = "2024-06-15"
    }
};

var credential = vcIssuer.Issue(
    "https://university.edu/credentials/degree",
    vcPayload,
    sdOptions,
    holderJwk);

Verify a Verifiable Credential

using SdJwt.Net.Vc.Verifier;

var vcVerifier = new SdJwtVcVerifier(keyResolver);
var expectedNonce = "nonce-123";

var result = await vcVerifier.VerifyAsync(
    presentation,
    validationParams,
    kbJwtValidationParameters: kbParams,
    expectedKbJwtNonce: expectedNonce,
    expectedVctType: "https://university.edu/credentials/degree");

var verifiedClaims = result.ClaimsPrincipal;
var verifiedVct = result.VctType;

Real-World Examples

  • Medical Licenses: Healthcare professional credentials
  • University Degrees: Academic achievement verification
  • Employment Records: Job position and verification workflows
  • Government IDs: Citizen identity credentials
