12      Using the Cosign project, OCI images may be signed to ensure supply chain
13      security is maintained. Those signatures can be verified before pulling into
14      a cluster. This policy checks the signature of an image repo called
15      ghcr.io/kyverno/test-verify-image to ensure it has been signed by verifying
16      its signature against the provided public key. This policy serves as an illustration for
17      how to configure a similar rule and will require replacing with your image(s) and keys.
