Overview

Print OpenSlide quickhash-1 checksums for one or more virtual slide files, in a format similar to sha256sum(1).

quickhash-1 is a non-cryptographic, 256-bit hash of a subset of a slide's data. It uniquely identifies a particular virtual slide, but cannot be used to detect corruption or modification of the slide file.
