Simply drag one or multiples files and drop them onto the main area of the application window. You can select which hashes you want calculated by selecting one or more of the checkboxes in the toolbar.

My day job requires that, every now and then, I transfer files into a secure network. One control we have in place to maintain the integrity of data, are file hashes. We check the hash before and after any file copy into the secure zone. This utility makes that process much simpler and faster.
