Hash Calculator

Hash Calculator is a lightweight and portable software application capable of calculating the SHA1, MD5 and CRC32 signatures of any files. It does not include configuration settings, making it accessible to advanced users and novices alike.
As installation is not a prerequisite, you can drop the EXE file anywhere on the hard disk and just click it to run.
It is also possible to save Hash Calculator to a USB flash disk or similar storage unit, in order to run it on any machine with minimum effort.
An important aspect to take into account is that it does not create new entries in the Windows registry, nor files on the computer, leaving it clean after removal.
The interface is based on a regular frame with a simple layout, where you can point out a file for calculating its SHA1, MD5 and CRC32 signatures using either the file browser or drag-and-drop support.
Fetching results is possible by just clicking a button. No additional configuration must be made beforehand. Each checksum can be copied to the Clipboard. However, you can copy all of them at once by extending the bottom part of the panel and clicking a button. There are no other features provided by this application.
As expected, Hash Calculator has minimal impact on computer performance, using low CPU and RAM. It finishes tasks almost instantly and without issues. No error dialogs were shown in our tests, and the tool did not hang or crash.
Although it does not comprise extensive features, Hash Calculator delivers a simple solution for rapidly calculating the SHA1, MD5 and CRC32 checksums of any files.
