Would you like to explain a bit such schemes? I am aware, for example,
that GnuPG on a mini offline laptop can beat *all* smartphone crypto
messenger, when it comes to endpoint security, when used with a dumb
phone with a USB port and while sending GnuPG MMS messages. All
users need for that is a software from GitHub, which can convert GnuPG
messages to .png images and back. Simply search there for 'imgify'.
https://github.com/dmshaw/paperkey/ is one such scheme, intended for
making a private key back-up. It could probably be adapted to store
arbitrary data.
There may be others, I just can't put my finger on them now.
Ah ok, you referred to encoding key material.
I just did a quick look and found this, which I may explore a little.
