I know theres AES and PGP, but all electronics stuff still has backdoors. You can’t backdoor a piece of paper and a writing utensil.

That’s no longer a one time pad. That’s closer to a homebrew stream cipher with the weakness of having a key that you just hope no one notices.
Neat, yeah Wikipedia says steam cipher approximate one time pads but can also be completely insecure.
I think it would take one hell of an effort to crack, it would be like 3MB encryption right? Or if they guessed the scheme they could try all mp3s ever torrented XOR’ed in every possible combination.
Idk I think there’s something workable there but I only having a casual knowledge
Also I think OP wanted pen and paper so maybe use a book instead digital files.
