VouchProtocol.Core (.NET SDK)

The .NET SDK for the Vouch Protocol (#34). It P/Invokes the canonical Rust core (vouch-core) through its cbindgen C ABI, so .NET apps verify credentials with the exact same bytes as every other Vouch SDK. Apache-2.0.

What you get

  • JCS canonicalization, Ed25519, did:key/multikey
  • Data Integrity proofs (eddsa-jcs-2022): sign + verify, with validity-window checks
  • Post-quantum dual-proof and composite verification
  • BitstringStatusList revocation checks

Build

./build-native.sh     # builds the host native lib into runtimes/<rid>/native
dotnet test           # builds the library and runs the xUnit suite

Run build-native.sh on each platform you target (Linux, macOS, Windows) so all runtime identifiers are populated. The native library is bundled in the NuGet package under runtimes/<rid>/native, so consumers need no extra setup.

Use

using VouchProtocol.Core;
using System.Text.Json;

using var kp = JsonDocument.Parse(Vouch.GenerateEd25519());
var seed = kp.RootElement.GetProperty("seed_b64").GetString()!;
var pub  = kp.RootElement.GetProperty("public_b64").GetString()!;
var did  = kp.RootElement.GetProperty("did_key").GetString()!;

var signed = Vouch.Sign(credentialJson, seed, did + "#key-1", "2026-04-26T10:00:00Z");
bool ok = Vouch.VerifyProof(signed, pub);
var result = Vouch.Verify(signed, pub, nowIso);  // JSON {proofValid, timeValid, valid}

Binary values are base64 strings; credentials and proofs are JSON strings. Methods throw VouchException on error.

Interop

The xUnit suite includes a cross-implementation test: .NET verifies the shared eddsa-jcs-2022 vector and reproduces its exact proofValue through the native core. A proof built here verifies in every other Vouch SDK.
