Configure gitsign for keyless Git commit signing using Sigstore Fulcio and Rekor, and verify signed commits

domain: docs.sigstore.dev · 6 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed

Verified steps

  1. Install gitsign: download the binary from the sigstore/gitsign releases page or via your package manager
  2. Configure Git to use gitsign as the signing program: git config --global gpg.x509.program gitsign and git config --global gpg.format x509
  3. Enable automatic commit signing: git config --global commit.gpgsign true
  4. Make a commit; gitsign will open a browser-based OIDC flow (or use the ambient OIDC token in CI) to obtain a Fulcio certificate and record the signature in Rekor
  5. Verify a commit with gitsign verify --certificate-identity <expected-identity> --certificate-oidc-issuer <expected-issuer> HEAD
  6. For CI environments, set GITSIGN_CONNECTOR_ID and ensure the OIDC token is available as an environment variable so gitsign authenticates non-interactively
