A: Take a look at Paperkey, https://wiki.archlinux.org/index.php/Paperkey; I think it serves this need well. Not to diminish your work, good job! It's probably a good thing to have diversity in implementations, so we don't get stuck with the only thing being written in OCaml.
B: I'm not well versed in Python, but have you tried `pip install qrencode`? C: If you're using an rsa4096 key, extracting just the secret key with paperkey will just barely fit in a QR code, and if you have subkeys then just forget it with "export-minimal". This, to me, is a good reason to migrate to an ed25519 key which is a deci-order of magnitude smaller (e.g. https://philihp.com/assets/id_ed25519.png) On 2020-09-14T08:16:19-0400 bexnews--- via Gnupg-users <gnupg-users@gnupg.org> wrote 7.3K bytes: > Hello Friends, > > Ok I am no coder so I am trying to bungle my way thru setting up > paperbackup.py. > > My goal was to be able to print out a paper encrypted backup of a strong > key that I can use to encrypt data or other keys.
