A simple paper backup tool
If you are working with GnuPG or SSH, you will probably understand the fear of losing your keys. This tool makes a "hard copy" of your text files including but not limited to your keys, 2FA backups, config files etc.
Papyrus can produce a PDF output which consist of QR codes made from your file to restore easily, in addition to OCR-friendly plain text version of your file, to prevent any failure on QR codes, with checksums for each line.
My personal recommendation is to print your paper backup with laser printer to acid-free paper, put it into a plastic bag (Mylar is preferred) and seal it with a heat sealer (you can find one around 25 USD, also useful for food packaging).
