WithInsecure passes name.Insecure to GetBundles/VerifyImageAttestations for v3 bundle discovery on HTTP registries. Follows the same pattern as notation's WithInsecureRegistry. WithTLSConfig passes a *tls.Config to the Rekor client, supporting private CAs from certSecretRef. Replaces the cosign CLI rekor wrapper with a direct rekor.GetRekorClient call to thread the option through. Includes a test using a fake non-loopback hostname to verify the insecure option is required for bundle discovery on HTTP registries. Signed-off-by: leigh capili <leigh@null.net>
Pass obj.Spec.Insecure and transport.TLSClientConfig to the cosign verifier so v3 bundle discovery and Rekor connections use the same transport settings as the registry. Signed-off-by: leigh capili <leigh@null.net>
…hart OCI Pass clientOpts.TLSConfig and clientOpts.Insecure to the cosign verifier in makeVerifiers so that HelmChart verification of OCI-sourced charts works against registries behind private CAs and on HTTP. Signed-off-by: leigh capili <leigh@null.net>
