Exporting for Universal Windows Platform
========================================

There's no extra requirement to export an ``.appx`` package that can be
installed as a Windows App or submited to the Windows Store. Exporting
packages also works from any platform, not only on Windows.

However, if you want to install an run the app, you need to sign it with a
trusted signature. Currently, Godot supports no signing of packages and you
need to use externals to tools to do so.

Also, make sure the Publisher name you set when export the package matches
the name on the certificate.

Creating a signing certificate
------------------------------

This requires the tools ``MakeCert.exe`` and ``Pvk2Pfx.exe`` which comes
with the Windows SDK. If you use Visual Studio, open one of its Developer
Prompts since they come with those tools available and in the path.

You can get more detailed instructions from `Microsof documentation
<https://msdn.microsoft.com/en-us/library/windows/desktop/jj835832(v=vs.85).aspx>`__.

First, run ``MakeCert`` to create a private key::

    MakeCert /n publisherName /r /h 0 /eku "1.3.6.1.5.5.7.3.3,1.3.6.1.4.1.311.10.3.13" /e expirationDate /sv MyKey.pvk MyKey.cer

Where ``publisherName`` matches the Publisher Name of your package and
``expirationDate`` is in the ``mm/dd/yyyy`` format.

Next, create a Personal Information Exchange (.pfx) file using ``Pvk2Pfx.exe``::

    Pvk2Pfx /pvk MyKey.pvk /pi pvkPassword /spc MyKey.cer /pfx MyKey.pfx [/po pfxPassword]

If you don't specify a password with ``/po`` argument, the PFX will have the
same password as the private key.

Signing the package
-------------------

Using the ``SignTool.exe`` this requires a single command:;

    SignTool sign /fd SHA256 /a /f MyKey.pfx /p pfxPassword package.appx

Installing the package
----------------------

After Windows 10 Anniversary Update you can install packages by just double
clicking the ``.appx`` file from the Windows Explorer.

It's also possible to install using the ``Add-AppxPackage`` PowerShell cmdlet.

Note that if you don't update the version number, you'll have to uninstall the
previous installed package before reinstalling it.
