It was created by Christopher Gurnee and is hosted on GitHub. This version of HashCheck is much newer and from 2016. Notable improvements include multithreading support, adding SHA-256 and SHA-512 (MD4 has been removed), calculating only selected checksums, adding extra translations, and digitally signing the files/installer.

The Save button can save the selected file checksums into a separate list for each hashing method which you can load later on to see if any of the files have changed.Ī list can be created quickly from the context menu by right clicking on the file(s) and selecting “Create checksum file”.Īs HashCheck is open source software, someone has taken the original code and updated it while adding some new features. Values for CRC-32, MD4, MD5, and SHA-1 will be shown in the window. Right click on one or more files or a folder and go to Properties > Checksums. The tiny (85KB) installer simply registers HashCheck.dll on the system so it’s very light on resources. A more recent version is available on GitHub which we’ll also mention below.

The original Hashcheck is from 2009 but seems to work fine in Windows 10. You’ll get an extra tab called Checksums alongside the standard tabs of Compatibility, Details, Previous versions and etc.

HashCheck works in a slightly different way to a traditional checking tool because it integrates into the system’s file properties window.

Here we show you 10 different tools that can calculate and compare hash values, they were tested on Windows 10 and 7. If you have something like an MD5 or an SHA based hash value from a website and want to check the integrity of the downloaded file, a way to calculate its hash value is required. All the official Windows ISO images will have an SHA-1 hash listed somewhere online which you can then compare against to see if the one you downloaded is identical to the original. A prime example is ISO images for operating systems like Linux and Windows.

A couple of popular hash algorithms are MD5 and SHA-1 and you will sometimes see these values listed on website download pages. If even one byte in the file changes, the value given when the check is run again will be different.

Every file has unique data contained within it, and when you apply a certain algorithm called a “cryptographic hash function” to it, a string value is returned which is only valid for that file in its current state. Or you can verify a file’s integrity by checking its hash value. One of the ways you can identify whether a file has been changed from its original state is to check its digital signature. This could either be by the site you are downloading from, corruption due to errors in the download process, an individual who has uploaded the file for you, or possibly the most dangerous, the file has been infected by malicious software. No error dialogs were shown in our tests, and the app did not hang or crash.Īll in all, SHA1Sum offers a simple method for calculating and comparing SHA1 signatures with minimum effort.When you download a file from the internet, quite often you cannot be 100% guaranteed that the file has not been changed in some way from the original. It has a good response time and quickly finishes a task. Note that the processed files must be placed in the same directory as SHA1Sum.Īs expected, the application has minimal impact on system performance, running on a very low quantity of CPU and RAM. You can compute an SHA1 signature, save it to an external file, as well as check the SHA1 checksm of an existing file and compare it with another. What's more, the Windows registry does not get updated with new entries, and files are not left behind on the HDD after removing the tool. It is also possible to save SHA1Sum to a USB flash disk or similar storage unit, in order to run it on any machine without prior installers. Installation is not required, so you can drop the program files somewhere on the hard disk and call SHA1Sum's process from a Command Prompt dialog. While most users prefer graphical interfaces with an intuitive structure for performing a simple task, some of them would rather work with a Command Prompt dialog, since a few inputted lines are usually enough to get the job done in no time. It comes packed with few features that can be quickly learned. SHA1Sum is a command-line application that enables users to calculate and compare the SHA1 checksums between two files.
