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.
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!
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!
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.
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.
Great utility & sorely needed on the Mac.
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
