Step 7 - Save Encryption Keys
-----------------------------

SavaPage creates the
``/opt/savapage/server/data/encryption.properties`` file at first
installation. The encryption keys held in this file are used to store
:ref:`Encrypted Secrets <ch-security-encrypted-secrets>` and 
:ref:`Document Signatures <ch-security-document-signature>` in the database.

*Make a backup of this file now, and store it at a secure place, so you
can restore it when you need to* :ref:`migrate to a new server <app-migrating>`.

.. warning::

   The ``encryption.properties`` file is *crucial* for decrypting secret
   data in the database and verifying the authenticity of document
   signatures. When you lose this file you won't be able to use any
   database copy which was based on its encryption keys **ever**.
