[[!meta title="Calculating checksums using GtkHash"]]

[<span class="application">GtkHash</span>](http://gtkhash.sourceforge.net/)
allows you to calculate [[!wikipedia checksum desc="checksums"]]. Checksums can
be useful to verify the integrity of a file, for example, if you downloaded it
from the Internet.

     from the <span class="guimenu">Places</span> menu or the <span
     class="guilabel">home</span> icon on the desktop.

  1. Navigate to the folder containing the file that you want to calculate the
     checksum for.

  1. Right-click on the file and choose <span class="guimenuitem">Properties</span>.

  1. In the <span class="guimenuitem">Properties</span> dialog, click on the
     <span class="guilabel">Digests</span> tab.
