What are checksums, CRCs and hashes? What is required for a hash to be cryptographic, and how any of these affect your Mac? Some answers and explanations.
How can you check the integrity of important files you have stored in iCloud, or in a Time Machine backup, such as those made by Big Sur to APFS?
The command tool member of the Dintch suite for tagging files with their SHA256 digest, to keep a watch on their integrity.
They now run on macOS from El Capitan to Big Sur, on Intel and Apple Silicon Macs.
Nine more free apps available as Universal binaries, from Cirrus to xattred.
This can now be incorporated into your own scripts, to check the integrity of important files automatically.
Recommended for all users, particularly if you tag large folders using Dintch.
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?
