Takes a file digest and answers which released package version it is
Takes a file digest and answers which released package version it is. Useful for an artefact found in a container layer, a build directory or an attachment with no metadata attached. Hex and base64 input are both accepted and normalised, the digest length is checked against the declared algorithm before anything is fetched, and the response names every matching package version, since one artefact can be published under more than one coordinate.
