[[!comment format=mdwn username="gernot" ip="85.197.15.125" subject="Paperkey" date="2013-12-05T11:37:02Z" content=""" Regarding backups, have you considered using [paperkey](http://www.jabberwocky.com/software/paperkey/) (also [in Debian](http://packages.debian.org/search?keywords=paperkey))? It only stores a minimal amount of key data and formats it in a human-readable way. The result is mainly meant to be printed but `paperkey` would probably also be a good way to keep the size of QR codes down. I've actually recovered a key from a such a printed backup (using OCR) and it worked great thanks to line-wise checksums. Maybe you could create paperkey PDF files with a proper OCR font through the web app? """]]
