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.

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?
We take for granted that our files remain uncorrupted, but know that isn’t always true. How can we fix or even detect such changes?
