Paperback is a library that facilitates the creation of paper offline backups of small amounts of important data, such as encryption keys.

It is designed to be used for long-term paper storage. Arbitrary data to be backed up is encoded using QR codes and sixword English text.

By default, the backup data is GPG-encrypted with a symmetric passphrase to avoid exposing data to the printer (or scanner, assuming you cover the passphrase when scanning).


Typical usage will be through the paperback executable.
