FairStars HashFiles is a handy tool to have on your PC. Using this little tool, we can find the hashes of multiple files in seconds. It does not support a large number of the hashing algorithms but offers some very common algorithms like MD5, SHA1, SHA256 and CRC32. It appears to use the native Win32 API for calculating the file hashes which makes it a really fast file hashing tool.
This tool has a drag-n-drop user interface and allows you to drop a large number of files on its window. As soon as you drop the files, they are added to the list and starts to calculate the file hashes. By default, it calculates only the MD5 hashes. But you can quickly select which type of hashes are to be calculated from the toolbar – MD5, CRC32, SHA1, SHA256. You can select one or more of these algorithms at the same time. Selecting more of these algorithms will result in a longer time for calculation. In the list of files, it displays the file hashes and also some other information such as the full path of the files, the file sizes, as well as file dates.
You can copy the file hashes to the clipboard in order to compare them with the hashes obtained from the download websites. You can also save the hashes along with the list of the files in form of a plaintext file. The hashes can be displayed and saved either in lower-case or upper-case characters.
We tried it with very large files like the Windows 10 installation ISO (5.3 GB) and it took more than one and a half minutes to calculate MD5 and SHA1 hashes for the ISO file. Microsoft’s FCIV tool did the same job in only 1 minute and 10 seconds. For smaller files all the calculations were made instantly.
