![]() ![]() ago Thanks for that info, I had already tested another posters suggestion of Hashtab and that was perfect for my needs. ![]() If you'd rather use a hashing utility with an interface, QuickHash GUI and HashTools are good options. HashCheck is a shell extension that enables you to check various hashes in the 'properties' window. As Windows desktop software HashTab runs as a Windows shell extension and on the Mac, it is implemented as a Finder plugin. HashTab provides OS extensions to calculate file hashes and supports many hash algorithms such as MD5, SHA1, SHA2, RipeMD, HAVAL, and Whirlpool. The lack of a stand-alone interface can sometimes be a good thing and in this case with the native Windows approach is nice. The name suggests that the program may have been inspired by the freeware tool HashTab, which in my opinion is still a good application. Use Hashtab as a simple MD5 checker or for a more advanced file integrity check. No portable version is available since the application is a shell extension. Real world tests of the program done on my computer turned out to be clean. Out of the 4 detections, two are machine learning based "confidence" scores, which is generally a result of an application having a small user base flagged as false-positives. Warning: As is the case with new programs, there are some detections for this program on VirusTotal. Do note that this method does not save the file name to the clipboard, just the hash value. There is a simpler way to copy the hash values, just double-click on one of the values and it gets copied to the clipboard. The Copy to Clipboard option saves the same content, but to the Windows Clipboard The exported sumfile contains the Hash value of the selected file, followed by the name of the file. It will be saved in the algorithm that you choose, e.g.MD5. The Export to sumfile option can be used to create a checksum file that is readable by text editors and hashing tools. You can use it to check the integrity of a downloaded file. Get the hash value from the download page/developer's website and paste it in the "Check against" field, and OpenHashTab will tell you if the values match, or not. That's not all that the program is capable of. You don't need to restart Explorer for the changes to take effect, but you have to re-open the properties dialog. When you have made your selection, click the X button to close the window. You can disable or enable as many hash values as you want. Selecting it opens a pop-up menu that contains more hashing algorithms. How do you customize the program? There is a gear icon displayed in the Hashes tab, it's just below and to the right the hash values pane. By default, the tab will list the MD5, SHA-1, SHA-256, and SHA-512 values. It may take a moment for the values to appear. Click on it and you will see the hash values of the selected file. You won't find a new context menu rather right-click on a file and select the Properties option. The question mark icon will then change into a red X or a green check if the hash doesn’t match any of the calculated hashes or if it does match, respectively.Install the application and restart any Explorer window that is open so that the new menu option becomes visible. Instead of eyeballing the results and the provided hash, you can just paste the provided hash into the blank below. HashTab adds a tab to the Properties window that displays the hash of the file. You just right-click the file and go to Properties. The application HashTab for Windows makes it a very simple, intuitive process to check the hashes of a file. To use the hash, you need to calculate the copy of the file you have to generate your own hash to see if they are identical. Different algorithms can be used to calculate hashes and the results might look like this: You can use these hashes to compare with the file you downloaded to ensure that the file hasn’t been tampered with or wasn’t corrupted during the download. Websites that provide downloads will often list accompanying CRC32, MD5, or other hashes to go along with the downloads.
