QuickHash GUI is an open-source Linux, Windows, and Apple Mac OSX graphical interface that enables easy and rapid data hashing of data : text, text files line by line, binary files, file comparisons, folder comparisons, disks and drive volumes (as administrator), Base64 data, as well as allowing files in one folder to be copied to another with data hashing conducted at either side for comparisons and data integrity.
It was originally designed for Linux, but is also available for Windows and Apple Mac OSX. MD5, SHA1, SHA256, SHA512 and xxHash hash algorithms are available.

We use it for forensic and utility verification files tools
I appreciate being able to obtain code-signed software.
Quickhash is fantastic!
Quickhash is reasonably priced, and works with most hash codes!
Ted Smith responds quickly if problems are reported!
The product is free, but the quality of the software justifies the inexpensive donation!
Thank you Ted!
QuickHash is easy to use, and does the simple security check that I want. Happy to pay for this.
I regularly use it for incorporating complex technical documents
QuickHash-GUI is a tool I regularly use for incorporating complex technical documents that cannot be adequately rendered in print into agreements if I cannot use agreements genuinely signed by a qualified electronic signature. It provides a quick and efficient way of identifying documents and other files securely.
It works simply and simply works
A “must have” piece of software
Ted Smith, thank you for your super helpful high performance tool
QuickHash-GUI is the perfect tool for capturing the originator proof of large amounts of data and thus for the protection of intellectual property.
With the «OSDSP Free-Proof» authors of media and measurement data (PDF, image, video, audio, text and so on…) can easily and free of charge anchor the hash of a QuickHash_GUI.csv file in the BLOCKCHAIN and in the OSDSP-REGISTER: https://www.mayerthaler.net/osdsp/ENG/
Very easy GUI. Makes hashing easy!
Best Graphical use of xxhash 32/64
I was searching for hashing program that made backup check an validation for big size files. The closest was blake2qs for cryptographical hashing, which would be fine, but its not my case. Thanks to Ted Smith and darealshinji. My next birthay I’ll be happy to donate something
Great utility & sorely needed on the Mac.
Used many hashing tools over the years, Quickhash is now my Hashing Tool of Choice
I use Quickhash all the time now and push it in my open source Internet investigation training courses. Simple to use for a variety of purposes. Students who have struggled with concepts of hashing material before find it very easy to use. It is cross platform which I personally like as I use Linux as my everyday platform.
Always happy to support someone who offers stuff like this to the community. I particularly like the feature of outputting the results to .csv or html file, very useful for embedding in reports.
Tool is exactly what we were looking for
Tool is exactly what we were looking for: a fast, easy to use, general purpose hashing tool that also worked across Windows and Mac. Very quick and helpful response when we had a question. Looking forward to some of the upcoming planned features.
Very intuitive and effective tool for all needs to calculate and confirm hashes
After a few days of using, I love this software.
I’m Professor at a University and I need this software for demonstrations during lectures. Great!
Very intuitive user interface, therefor easy to use. Covers all needs to calculate and confirm hashes. And: available for all platforms!
SHA256 Checksum Calculation for Dummies!
For years I have recognised the importance of verifying that the software I download is the original version, and not one that’s been tampered with, but, as a non technical user, I found it impossible to get to grips with command line prompts, so I’ve been playing a dangerous game…
Anyway, I went to download the ZenCash wallet the other day, and on their download page they wrote:
“Security check: You may decide to run a virus scan on it before proceeding… In addition using a tool such as http://quickhash-gui.org/ you may calculate the its SHA256 checksum.”
Not expecting to be able to make it work, I downloaded your software nonetheless, and was delighted when it worked flawlessly and without me needing any technical skills.
This is truly an answer to my prayers, so please accept my £20 donation with my sincere thanks!
QuickHash and File Backup Online
Having had serious problems with other backup/file-archiving methods, I now use the USAF Encryption Wizard (now called TENS, nothing to do with relief from pain) to encrypt-archive some crucial work files.
My procedure is to encrypt-archive the crucial files with the USAF Encryption Wizard and then I decrypt-expand the .wza file that the USAF Encryption Wizard has created to another folder. I then use QuickHash to check that the decrypted-expanded files are identical to the originals. Since there are over 180MB of crucial files, I cannot manually check each file, even though the USAF Encryption Wizard does support hashing files.
Without QuickHash I would be unable to use the method I currently use. The encrypted archive is uploaded to Dropbox, which does not support user-supplied encryption keys.
I have spot-checked the accuracy of what QuickHash is doing by using the USAF Encryption Wizard’s hashing function on some files. I did those spot-checks on an earlier version of QuickHash and will in due course do the same spot-check on the current version.
