QuickHash GUI is an open source hashing tool for Windows, Linux and macOS- gHacks Tech News

FastHash GUI is an open source hashing tool which is out there for Windows, Linux and macOS. If you are a safety aware particular person or wish to confirm file integrity, e.g. for backups, it’s essential to concentrate on hashing.

Tip: we reviewed a number of applications to compute hashes up to now: you’ll be able to use PowerShell to generate hashes, or use the applications Hashing, HashTab Shell extension, or Nirsoft’s Hash My Files.

For those that aren’t right here is a quick description.

What is a hash worth? Why is it vital?

QuickHash GUI is an open source hashing tool for Windows, Linux and macOS

A hash worth is an alpha-numerical string calculated by an algorithm which determines the integrity of a file. Every file has a hash worth and the worth is distinctive for every file.

The most typical utilization of hashes are to cross-verify them with the values given on the obtain web page of digitally distributed content material (software program, Android ROMs, apps, and so forth). If the values given by the developer and the downloaded file are an ideal match, it means the file has not been tampered with throughout transport.

If the values are completely different, one among two issues are possible. Either the downloaded file is corrupted, or worse, the file has been modified by somebody.

Tip: You can see how this works your self. Create a textual content in notepad, or doodle one thing in Paint and reserve it. Those recordsdata may have hash values of their very own. Note them down, edit the recordsdata and save them. Look on the hash values once more, they need to be completely different.

FastHash GUI

The interface (or GUI, if you’ll) of FastHash GUI is fairly easy. It has a tab bar with a number of tabs, every of which shows a set of choices. There is a side-bar which is persistent throughout all screens. It homes the algorithm panel and the System RAM panel, which reveals your laptop’s whole RAM, and out there RAM).

You can choose one of many 5 algorithms: MD5, SHA-1, SHA-256, SHA-512 and xxHash32, and FastHash will compute the corresponding worth.

Tip: MD5 is not precisely safe. So I like to recommend utilizing one of many different choices, all of that are cryptographic hash capabilities.


This is the second tab of this system. The cause I am starting right here is as a result of it could assist in making it simpler to grasp how hash comparability works. You can use the “choose file” button within the tab to navigate and select the file which you wish to examine, or drag and drop one to the interface, and the computed hash worth of the file will probably be displayed slightly below the button.

Copy and paste the hash worth from the developer’s web site within the “Expected hash worth” subject, and if each values are the identical, FastHash will show a message saying they match. You can swap the case of the checksum from decrease to UPPER utilizing the choice above the anticipated hash worth subject.

Let’s examine the hash of a KeePass archiv (check with the above picture). You can get the hash worth posted by the developer, and use it to match the hash of the file which you downloaded from the web site.

Tip: Spaces matter. FastHash doesn’t embrace areas within the computed hash subject, so if you happen to paste an anticipated worth that has areas, they will not match. Delete the areas manually to get the “matches” pop-up.


Text has its personal hash values. You can use the textual content tab to sort or paste some textual content and see its worth displayed within the subject on the underside. This tab has 2 buttons which can be utilized to transform the case of the textual content (Make UPPER and Make decrease), and a transparent textual content button. You may also configure the appliance to hash textual content, or an total file, line-by-line.


This tab allows you to compute hashes for all recordsdata in a folder. It consists of sub-folders, however you’ll be able to optionally disable that. You can set wildcards utilizing the file varieties choice, to solely compute the values of the recordsdata within the outlined format. It even has an choice to work with hidden folders, which might be helpful in case you are checking the System listing.

This is a really helpful choice if you end up transferring knowledge. Use the left pane to pick out the source folder which has the recordsdata that you simply want to copy. Now choose the vacation spot folder the place you need the content material to be copied to utilizing the precise pane.

Hit the Go! button and FastHash will provoke the method. The program will hash the values of the source recordsdata, copy the content material over, and re-hash (checks the values of the copied content material). It helps in avoiding corrupted recordsdata or errors in the course of the copying course of.

You can set customized choices to solely listing sub-folders or sub-folders + recordsdata, wildcards, ignore sub-folders. FastHash additionally shows the variety of recordsdata within the folder, a progress bar, the beginning time, finish time and the whole time it took for the method to be accomplished. Optionally, it can save you the outcomes to a CSV.

The file and the recordsdata tabs, and the Compare two recordsdata tab have a “Start at a time” choice. This is a timer, which routinely executes the hash computation, utilizing the outlined choices.

Compare Two Files

FastHash GUI can be utilized to match the hash values of two recordsdata. You simply want to pick out the 2 recordsdata, and use the evaluate now button. The outcome will let you know if they’re a match or a mis-match.

Compare Two Folders

This is much like the above choice, however used to match two folders. A results of the comparability might be saved in a textual content, if you happen to use the Log outcome choice.


Disks and Base64

Want to examine an total disk’s hash? You can achieve this with this system. But, within the Windows model, you’ll be able to solely run the SHA-1 algorithm to examine bodily disks, and you additionally have to run this system with administrator privileges. FastHash GUI can be used to decode Base64 knowledge from recordsdata.

FastHash GUI is a conveyable utility, and helps 32-bit and 64-bit methods.

Hashtab is a superb different for FastHash, although the previous hasn’t been up to date in 2 years.
