And anyone know about OSX? Would OSX use the getentropy the article you linked to mentions for OpenBSD?
As far as I can see, there's no "getentropy" on macOS. I see references to it online, but I cannot find it in any header files.
Or something else?
I found something called "arc4random" and a couple of related functions [1].
Or just fallback to /dev/(u)random?
/dev/(u)random does exist on macOS. This is what Apple seems to recommend [2].
