Sigstore Code Signing

Definition

Sigstore is a free, open-source project that makes code signing accessible for software artifacts by using short-lived certificates tied to OIDC identities instead of long-lived private keys. Signatures are recorded in a transparency log (Rekor) that provides tamper-evident proof of signing events.

Sigstore is rapidly becoming the standard for signing container images, npm packages, and Python distributions.
