> be sure to store the hash type as well so that you can change it later if needed

Thanks for sharing this, I'd been doing this on my own for my own stuff (eg. foo.txt-xxh32-ea79e094), but it's good to know someone else has thought it through.

I ran into the problem once where someone had named some files foo-fb490c or something similar without any annotation, and when there was a problem, it took a file to figure out they were using truncated sha256 hashes.
