A simple paper backup tool for GnuPG or SSH keys

by Flutter Awesome

Papyrus

About

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).

Installation

Go to the Releases page and download the package for your distribution and signatures.

Checksum and signature verification

  1. Download release files and checksums
  2. Get my GnuPG key to verify checksums
gpg --keyserver keyserver.ubuntu.com --recv-keys D854D9D85CB4910704BD9C5B2D33E2BD3D975818
  1. Verify SHA256SUMS file by running:
gpg --verify SHA256SUMS.asc
  1. Verify SHA256 checksums with:
sha256sum -c SHA256SUMS
