I Have The Power
I Have The Power is a small and educational Windows utility designed to help users learn a little more about hashes. This approachable tool does not include complicated features or configuration settings, so it can be handled by anyone.
As there is no setup pack implies, you can save the EXE file anywhere on the hard disk and launch the tool by just clicking it.
This also means that you can save I Have The Power to a pen drive or other removable storage unit, in order to run it on any computer, without having to install anything beforehand.
The important aspect about it is that the app does not modify Windows registry or create extra files on the disk, so it does not leave any traces behind once it is removed.
Simple interface and options
The GUI is user-friendly, consisting of a regular window with a well-defined structure containing few UI elements. Pointing out a file is possible with the help of the file browser only, since the drag-and-drop method is not supported.
All you have to do is click the button of the checksum type you're interested in, and view the file's signature, number of zeros, and other technical data. I Have The Power offers support for MD5 (128 bits), SHA1 (160 bits), SHA256 (256 bits) and SHA512 (512 bits). Unfortunately, the app does not implement options for copying this information to the Clipboard, saving it to file, or printing it.
Evaluation and conclusion
As expected, the tool leaves a small footprint on system performance, since it runs on low CPU and RAM. It calculates hashes rapidly and displays information just the same. We have not come across any problems in our tests, since I Have The Power did not hang, crash or pop up error dialogs. Although it is not feature-rich, the tool provides useful information about the hash of any file.
