  &krusader; checks which tools you have
  and if those tools allow recursive operation (in case you
  selected folders), you can generate a checksum by choosing a
  checksum type from the list (<guilabel>md5</guilabel>,
  <guilabel>sha</guilabel>, &etc;). You can then save the
  checksum to a file, usually called <filename>checksum.md5</filename>
  or <filename>checksum.sha1</filename>.</para>

  &krusader; checks if you have a tool that
  supports the type of checksum you need (from your specified
  checksum file) and displays the files that failed the checksum
  (if any).</para>
  <para>The system abstracts over different checksum mechanisms and
  Checksum Utilities. At the moment, the following checksums are
  supported: md5, sha1, sha256, sha224, sha256, sha384, sha512,
  tiger, whirlpool, cfv and crc. Please check your
