Record details and sources

Overview

Sigstore combines signing clients with certificate and transparency-log infrastructure. Cosign signs and verifies artifacts; Fulcio binds short-lived certificates to identities; Rekor records signing information. These components can work together or independently. Sigstore is a concrete software framework and public service ecosystem, not a generic name for artifact signing.

Typical use cases

Audit signing events through a transparency log.source 1
Sign and verify release artifacts, container images and SBOMs.source 1

Strengths

Clients can use a hosted public deployment or independently configured trust infrastructure.source 1 · source 2
Identity-based signing uses short-lived certificates and ephemeral keys, reducing the need for long-lived signing-key management.source 1

Limitations

Compromised identity providers or certificate-authority services can produce unauthorized certificates; detection depends on monitoring transparency logs.source 1
Verification must check the expected signer identity and issuer as well as cryptographic validity; a valid signature alone is not an assurance that software is safe.source 1 · source 2
