Sigstore
A .NET library for generating and verifying Sigstore signatures.
Overview
Sigstore is a pure .NET implementation of the Sigstore Client Specification. It supports keyless signing and verification using the Sigstore public good instance (Fulcio, Rekor, RFC 3161 TSA) — no external tools required.
Features
- Keyless signing — ephemeral ECDSA P-256 keys tied to OIDC identities
- Bundle verification — full Sigstore bundle verification (v0.1, v0.2, v0.3)
- Certificate validation — hybrid time model per RFC 5280
- Transparency log — Merkle inclusion proof and checkpoint verification
- RFC 3161 timestamps — timestamp authority integration
- DSSE attestations — in-toto statement signing and verification
- DI-friendly — constructor injection with sensible defaults
- AOT-compatible — fully trimmer and NativeAOT safe
Quick Start
Verification
using Sigstore;
var verifier = new SigstoreVerifier(trustRootProvider);
var policy = new VerificationPolicy
{
CertificateIdentity = CertificateIdentity.ForGitHubActions(
owner: "owner",
repository: "repo")
};
var result = await verifier.VerifyStreamAsync(artifactStream, bundle, policy);
Signing
var signer = new SigstoreSigner(fulcioClient, rekorClient, tsaClient, oidcProvider);
SigstoreBundle bundle = await signer.SignAsync(artifactStream);
string json = bundle.Serialize();
Bundle I/O
SigstoreBundle bundle = SigstoreBundle.Deserialize(json);
string json = bundle.Serialize();
