SHA256
This can now be incorporated into your own scripts, to check the integrity of important files automatically.
A nimbler version of Dintch is designed to drag and drop files and smaller folders to tag then and check their integrity.
More about checking the integrity of files on macOS, with a new version of a free utility, news of the next apps, and error-correcting code perhaps?
To check the integrity of important documents, we’re going to calculate their SHA256 digests. But where should those be stored if HFS+ and APFS don’t have a suitable attribute?
If macOS can’t do it, how should we check the integrity of important files? Use a checksum, or a hash function? And which?
