Answer
TLS and SHA256 digests ensure confidentiality and integrity.
Quick Answer
Copying images between registries (registry-to-registry) is done with tools like crane, skopeo, or docker pull + push. These transfer image manifests and only the layers the destination registry doesn't already have. TLS is used in transit; content-addressable SHA256 digests verify integrity on both ends.
