Image Signing and Verification in Quay Repository Mirroring

Solution Verified - Updated -

Issue

  • We are mirroring various official/trusted images from Docker Hub and would like a way to sign the images to verify authenticity when mirrored.
    Or also verify if an image has been signed.
    Is there any functionality like this currently available in Quay for mirroring?
