软件包摘要
Automates, normalizes, and verifies software artifact provenance
历史
项目历史与用法
Witness is an in-toto supply-chain security CLI for producing and verifying attestations about software artifacts and build steps. The project describes itself as a pluggable framework that automates, normalizes, and verifies software artifact provenance, combining attestation generation with a policy engine.
项目历史
Witness originated at TestifySec and was later donated to the CNCF in-toto ecosystem. TestifySec's open-source statement dates the formal donation of Witness and Archivista to January 2024, after ratification by the in-toto steering committee, giving the project community governance under the same ecosystem as the in-toto specification.
采用历史
Witness sits inside the broader in-toto adoption story. CNCF records in-toto as accepted on August 14, 2019, moved to Incubating on March 10, 2022, and Graduated on February 10, 2025. That matters for Witness because it implements the in-toto specification in a CLI intended for real pipelines, and its README points users to CNCF Slack channels and open community meetings rather than a vendor-only support path.
The project is also tied to adjacent supply-chain standards and systems. The Witness README lists support for in-toto enhancement work, OPA Rego policy, Sigstore and SPIFFE/SPIRE signing paths, timestamp authorities, and Archivista storage, reflecting the post-SolarWinds era movement toward verifiable build provenance, signed attestations, and policy-driven release gates.
使用方式
A typical Witness workflow runs a command under `witness run` during a build or release step, collects attestations from configured attestors, signs them, and later verifies the resulting collection against a signed policy. The goal is to answer who performed a supply-chain step, what materials and products were involved, and whether the step satisfied policy before an artifact is trusted or deployed.
为什么软件包爱好者会关心
For package and release engineers, Witness is significant because it turns provenance from a document attached at the end of a release into machine-verifiable metadata emitted by each lifecycle step. It is part of the same tooling vocabulary as SLSA provenance, Sigstore signing, OPA/Rego policy, and SBOM/attestation storage, making it a package-nerd tool for proving how an artifact came to exist.
