Self-hosted Sigstore: the Fulcio certificate authority, the Rekor v2 transparency log and the Timestamp Authority in one install, for keyless signing with cosign against your own infrastructure.
Version
The latest line lives at the base page; older lines have their own page so you can pin and verify exactly that version. Only the most recent releases are listed — an older chart pins an older image digest.
Deployed image digest

oci://ghcr.io/quenchworks/charts/sigstore-stack:0.0.9The chart pins its image by this signed digest, so you never track it yourself. Signatures, SBOM, and provenance attach to the same digest.
