DRM ?

[TjapDjemboet]

*disclaimer i don't know programming, coding, scripting or some shit like that. just curiousity from a dumb fuck person*​

so learning a bit won't hurt right? even though it'll never enter my brain. my question is : what is hash on drm? is it some kind of key?

like image above, i can download the file but i can't open it. do i need to insert the hash? (if it involving a PC, i give up). thx.
