| # Heavily depends on: | |
| # libqrencode (fukuchi.org/works/qrencode/) | |
| # paperkey (jabberwocky.com/software/paperkey/) | |
| # zbar (zbar.sourceforge.net) | |
| # Producing the QR codes: | |
| # Split over 4 codes to ensure the data per image is not too large. | |
| gpg --export-secret-key KEYIDGOESHERE | paperkey --output-type raw | base64 > temp | |
| split temp -n 4 IMG | |
| for f in IMG*; do cat $f | qrencode -o $f.png; done |
Run pdflatex --shell-escape gpgbackup.tex to produce a pdf that you can print and lock away.
In order to recover the key, you will have to scan extract individual QR Codes with names IMGa.png, IMGb.png, IMGc.png and IMGd.png, as given in the name of each figure, then run the recovery commands.
NOTE: The above command WILL leave some artefacts in /tmp which should be removed using the command rm /tmp/IMG*png
