As of this writing, ggbutcher’s program already does exactly what it’s supposed to do for the simple raw file formats that it can handle. I think it is already a good, working proof-of-concept program.
I’m already using it to calculate hashes for a bunch of older raw files going back 15+ years, testing multiple file types, and incorporating the hashes into my workflow to see what kinds of issues I encounter in my particular scenarios.
I might eventually write an FAQ to address the questions that keep coming up.
