Cryptoknife is an open source portable utility to allow hashing, encoding, and encryption through a simple drag-and-drop interface. It also comes with a collection of miscellaneous tools. The mainline branch officially supports Windows and Mac. Cryptoknife is free and licensed GPL v2 or later. It can be used for both commercial and personal use. Cryptoknife works by checking boxes for the calculations and then dragging files to run the calculation. Cryptoknife performs the work from every checked box on every tab and displays the output the log and saves to a log file. By default, very common hashing boxes are pre-checked.
