'Implements Sigstore-based software signing and verification using Cosign.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Implementing Sigstore for Software Signing ## When to Use - Signing container images and software artifacts without managing long-lived cryptographic keys - Establishing verifiable provenance for build outputs in CI/CD pipelines using OIDC identity binding - Querying the Rekor transparency log to audit when and by whom an artifact was signed - Verifying that container images pulled from registries were signed by authorized identities and issuers - Integrating Sigstore verification into Kubernetes admission controllers to enforce signed-image policies **Do not use** for signing artifacts that require air-gapped or offline signing workflows where OIDC authentication is unavailable, for environments that cannot reach the public Sigstore infrastructure (Fulcio, Rekor) and have no private instance deployed, or as a replacement for traditional PGP/GPG signing where regulatory compliance mandates specific key management procedures. ## Prerequisites - Cosign CLI v2.4+ installed (`go install github.com/sigstore/cosign/v2/cmd/cosign@latest` or binary release) - Access to an OIDC identity provider supported by Fulcio (Google, GitHub, Microsoft, or a custom OIDC issuer) …

How to install
mdr add adriannoes/awesome-agentic-ai/implementing-sigstore-for-software-signing@sha256:4f1db3501f4427d3The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
