Qthashsum
Version: 1.6.0 Web: https://github.com/ fffaraz/qthashsum
There are many ways to check the integrity of a downloaded file. In those cases when we use Windows, Hashtab is good (it adds an extra tab to the file properties dialog). In Linux it’s the command line md5sum and the graphical Gtkhash. If you need more features or smoother exterior, try Qthashsum.
This small and practical accessory looks like a Swiss Army knife. A one-person project created by Faraz Fallahi, Qthashsum offers a lot more than just a hash checker. We examined all its features and concluded that excessiveness isn’t always a negative trait. Qthashsum has five tabs, each for a specific purpose. The first one does the main thing: it calculates checksums using MD5, SHA1, SHA2 and SHA3. It’s up to you to decide what algorithm will be used, and it is also possible to select several options at once. Make the choice, select the source file and hit Start – Qthashsum will show a separate window with results.
The second tab is Create Digest, which searches for duplicate files. Select a directory, a hash method out of several options that include flavour of MD4, MD5, SHA3 and KECCAK, and an output format. This feature doesn’t modify your filesystem in any way – it only suggests duplicate files based on matching hash sums. The third tab is for Settings – it is currently only possible to define the number of CPU cores engaged in hash calculations. Then there’s the About tab, and finally the last one is Restic! Much to our surprise, Qthashsum sports a neat integration with Rest, a robust backup system written in Go (https:// github. com/restic/restic). To make things work for you, it is important to edit the path to the ‘restic’ executable, define source and target paths and optionally change some Restic parameters (see the FORGET field).
