Project history and usage

Rekor CLI is the command-line client for Rekor, Sigstore's transparency log for signed software-supply-chain metadata.

Project history

Rekor was developed within Sigstore to provide an immutable, tamper-resistant ledger for signed software-supply-chain metadata. It combines a REST API server and transparency log with rekor-cli for submitting and verifying entries.

Rekor reached the stable 1.0 line after several years of pre-1.0 development. Rekor v1 later entered maintenance mode while Sigstore developed a tile-backed Rekor v2 architecture intended to reduce operational complexity and cost.

Adoption history

Rekor became Sigstore's signature-transparency component and provides a public production instance with operational availability commitments. The CLI is distributed as release binaries, container packages, and a Homebrew formula.

Its role in Sigstore placed transparency-log verification in mainstream software-supply-chain workflows, alongside Fulcio certificates and Cosign signing and verification.

How it is used

Maintainers use rekor-cli upload to submit signed artifact metadata. Verifiers use verify to check inclusion, get to retrieve entries, loginfo to validate signed tree information, and search to locate records by artifact, public key, or digest.

The CLI can cache the log's public key in ~/.rekor/rekor.yaml. Artifact signing keys are supplied explicitly to relevant commands and are not stored by Rekor as client credentials.

Why package nerds care

rekor-cli gives maintainers and verifiers direct access to an append-only software-supply-chain ledger. It exposes upload, verification, retrieval, search, and log-integrity operations that help make artifact-signing events independently auditable.

Timeline

2022: Rekor 1.0 established a stable API line and production-ready public service
v1 era: Rekor served as Sigstore's signature-transparency component
2026: Rekor v1 was in maintenance mode while tile-backed Rekor v2 development progressed
