libqrencode VS keysmith

> I'm not sure that qrencode CLI tool will automatically do this for you.

If I'm looking at the correct repository, it does [1].

[1] https://github.com/fukuchi/libqrencode/blob/master/split.c

qrencode (https://github.com/fukuchi/libqrencode) can create text based output of qr codes in ANSI, ASCII and a UTF8 formats, you can pipe the output through sed to change the output.

This doesn't look "simpler" after a quick look, and it's a hard dependency of the GP solution.

(I completely agree on the local-only guarantee that this one provides, though)

If we are talking truly massive amounts though the absolute safest is probably an airgapped device with keysmith https://github.com/dfinity/keysmith and quill https://github.com/dfinity/quill. This technical option though that I would only recommend if you are technical and familiar with the command line.

Keysmith

If you are a little more technical and familiar with the command line you could use keysmith together with dfx or quill

But also note that you don't have to use Internet Identity to control an account holding ICP or neurons. You can use keysmith and nano to create a seed and private keys on an airgapped computer, sign transactions on that computer, and then transfer those transactions to a connected machine and submit them to the IC.
