I found the format somewhat difficult to digest. Is there are more
accessible version? I wonder if they used specifically hardened
devices, or just the regular CPU versions.

I'm not sure if that's worrying. I don't think a general-purpose
computing device I own should have private keys I cannot access or
read in the first place.
