# openslide-quickhash1sum(1)

Print OpenSlide quickhash-1 checksums

## NAME

openslide-quickhash1sum - Print OpenSlide quickhash-1 checksums

## SYNOPSIS

**openslide-quickhash1sum** \[**--help**\] \[**--version**\] *slide*...

## DESCRIPTION

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

*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.

## OPTIONS

- **--help**

  Display usage summary.

- **--version**

  Display version and copyright information.

## EXIT STATUS

**openslide-quickhash1sum** returns 0 on success, 1 if a *quickhash-1* could not be calculated, or 2 if the arguments are invalid.

## NOTES

**openslide-quickhash1sum** is a legacy command and no new features will be added. Its replacement is the **slide quickhash1** subcommand of [**slidetool**(1)](/slidetool/1.md).

## BUGS

*quickhash-1* is not defined for all slide files supported by OpenSlide. If a slide does not have a *quickhash-1*, "No quickhash-1 available" will be printed.
