I'd like to transfer files between cold and hot wallets via QR codes. Python can't seem to decode/encode the bytes in the unsigned tx file. Can someone confirm they are mostly binary, and some sort of encryption scheme? Is there a way to decrypt then before rendering in QR?
I'm able to use the bitstring library to make the files into ones and zeroes, and make QR of that, but I don't know how to go in reverse to reconstitute the file on the other side. Is there a method for covering from 10001101... To the file again?
