Rekor

Rekór - Greek for “Record”

Rekor's goals are to provide an immutable tamper resistant ledger of metadata generated within a software projects supply chain. Rekor will enable software maintainers and build systems to record signed metadata to an immutable record. Other parties can then query said metadata to enable them to make informed decisions on trust and non-repudiation of an object's lifecycle. For more details visit the sigstore website.

The Rekor project provides a restful API based server for validation and a transparency log for storage. A CLI application is available to make and verify entries, query the transparency log for inclusion proof, integrity verification of the transparency log or retrieval of entries by either public key or artifact.

Rekor fulfils the signature transparency role of sigstore's software signing infrastructure. However, Rekor can be run on its own and is designed to be extensible to working with different manifest schemas and PKI tooling.

Current State of Rekor v1

Rekor v1 is in maintenance mode.

We are actively developing a new version of Rekor designed to be easy to maintain and cheaper to operate. Building on the active development in the Certificate Transparency ecosystem, Rekor v2 will be backed by a tile-based log and will use a modernized version of Trillian, Trillian-Tessera.

Follow its progress on the rekor-tiles repo, and learn more about Rekor v2 on the proposal and design doc. As we near a V2 release, we plan to merge the rekor-tiles codebase into this repository.

Public Instance

Rekor is officially Generally Available with a 1.0.0 release, and follows semver rules for API stability. This means production workloads can rely on the Rekor public instance, which has a 24/7 oncall rotation supporting it and offers a 99.5% availability SLO for the following API endpoints: /api/v1/log /api/v1/log/publicKey /api/v1/log/proof /api/v1/log/entries /api/v1/log/entries/retrieve

For uptime data on the Rekor public instance, see https://status.sigstore.dev.

More details on the public instance can be found at docs.sigstore.dev.

The attestation size limit for uploads to the public instance is 100KB. If you need to upload larger files, please run your own instance of Rekor. You can find instructions for doing so in the installation documentation.

Installation

Please see the installation page for details on how to install the rekor CLI and set up / run the rekor server

Usage

For examples of uploading signatures for all the supported types to rekor, see the types documentation.

Verifying releases

Starting with Rekor v1.6.0, release binaries and container images can be verified using either GitHub Artifact Attestations (gh CLI) or Sigstore's release artifact signing key (artifact.pub with cosign).
