// GetSignatures returns the image's signatures.  It may use a remote (= slow) service.

GetSignatures returns the image s signatures . It may use a remote ( = slow ) service . If instanceDigest is not nil it contains a digest of the specific manifest instance to retrieve signatures for ( when the primary manifest is a manifest list ) ; this never happens if the primary manifest is not a manifest list ( e . g . if the source never returns manifest lists ) .
