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?
