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.

I’m certainly not an expert.
But could you generate pads from mutually accessible data sources?
Like use hit_me_baby_one_more_time_not_a_virus.mp3 appended with a password, as a seed in a pseudo random number generating algorithm, then do the same thing with another data source, repeat however many times, then XOR the generated numbers together, and use the result as a pad?
Steganography may be interesting in that vein. Hiding data within larger images / sound files etc.
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.
