Generate a SLSA provenance attestation for a build artifact using slsa-github-generator in GitHub Actions and verify it with slsa-verifier

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

Verified steps

  1. Add the slsa-framework/slsa-github-generator workflow as a reusable workflow call in your GitHub Actions pipeline after the build step; pass the artifact's name and digest as inputs
  2. The generator runs in an isolated GitHub-hosted runner and produces an in-toto provenance statement in SLSA v1 format, signed with a Fulcio certificate obtained via GitHub Actions OIDC, and records the attestation in Rekor
  3. Download the generated .intoto.jsonl provenance file from the workflow artifacts
  4. Install slsa-verifier: go install github.com/slsa-framework/slsa-verifier/v2/cli/slsa-verifier@latest
  5. Verify the provenance: slsa-verifier verify-artifact <artifact-path> --provenance-path <provenance.intoto.jsonl> --source-uri github.com/<org>/<repo> --builder-id https://github.com/slsa-framework/slsa-github-generator/.github/workflows/<workflow>.yml@refs/tags/<version>
  6. Confirm the output reports PASSED and shows the verified source repository and builder identity
