Game's PCK file encrypted
==================

Once you have compiled Godot export templates with encryption key, you can export your project's PCK file encrypted with the same key.


When exporting a game from Godot, there are 2 ways to add the encryption key.

#. Adding an environment variable with the key.
#. Uploading your ``export_credentials.cg`` file.


Adding Environment Variable
---------------------------

A very simple way to Encrypt your game resources, is to add an environment variable. In order to do this


#. Visit the **Matrix Blueprints** page.
#. Click **Create Game Matrix**.
#. Click the **cog icon** to configure the matrix.

       :alt: Godot Modal
#. Click Advance Settings
    .. image:: ../img/game/advance.png
       :alt: Advance
#. Enable **Environment Variables** by clicking the corresponding button.
    .. image:: ../img/enable.png
       :alt: Enable vars
#. Click the **Add +** button to add a new environment variable.

       :alt: Add env var
#. Set the variable name to:
    ``GODOT_SCRIPT_ENCRYPTION_KEY``

#. On the value field, use the same KEY as the one used when compiling Godot,

    .. image:: ../img/game/var_value.png
       :alt: Var name

The form should look like this

    .. image:: ../img/game/full_form.png
       :alt: Full form

Click Save

   If you don't, the variables will not be added.

To validate the variables were added, the Game Matrix should look like.

Uploading export_credentials.cfg
--------------------------------

Whenever you configure a password or key on your godot project, all of these values are stored in a file ``.godot/export_credentials.cfg``. In order to upload this file you do:

#. Visit the **Matrix Blueprints** page.
#. Click **Create Game Matrix**.
#. Click the **cog icon** to configure the matrix.
    .. image:: ../img/game/modal.png
       :alt: Godot Modal
#. Click Advance Settings
    .. image:: ../img/game/advance.png
       :alt: Advance
#. Under `export_credentials.cfg` drop down, click "+ New" button
    .. image:: ../img/game/new_file.png
       :alt: Advance
#. Select your project export_credentials.cfg file.
    .. image:: ../img/game/upload_file.png
       :alt: Advance

The form should look like this

    .. image:: ../img/game/full_form2.png
       :alt: Full form

Click Save
