history
Project history and usage
slsa-verifier is the SLSA project's command-line verifier for provenance attached to software artifacts. It is used in CI and release workflows to check that an artifact, image, or package was built by an expected builder from expected source inputs.
Project history
The GitHub repository was created in March 2022 and its first public GitHub release, v0.0.1, was published in May 2022. The README describes the tool as a verifier for SLSA provenance generated by CI/CD builders, including checks of cryptographic signatures and expected builder, source repository, and ref values.
Adoption history
The official README documents installation through Go, release binaries, a GitHub Actions installer, and a community-maintained Homebrew formula. The supplied package metadata also lists Homebrew, Nix, and zypper package names, showing distribution through both developer workstations and reproducible-build/package-manager ecosystems.
How it is used
Common usage is to run `slsa-verifier` in a release or dependency-ingestion path to verify provenance for artifacts, containers, npm packages, Google Cloud Build output, and GitHub build-provenance attestations.
Why package nerds care
Package maintainers care about slsa-verifier because it turns SLSA provenance, in-toto statements, and Sigstore-style attestations into a concrete command that can be wired into package publication and consumption workflows.
Timeline
- 2022: GitHub repository created.
- 2022: v0.0.1 published as the first GitHub release.
- 2025: v2.7.1 documented in the README install examples.
Related projects
- SLSA generator, Google Cloud Build provenance, GitHub build-provenance attestations, npm provenance, in-toto, and Sigstore are adjacent parts of the same supply-chain verification culture.
