Description: django-encrypted-filefield
        ==========================
        
        Encrypt uploaded files, store them wherever you like and stream them back
        unencrypted.
        
        
        Why This Exists
        ---------------
        
        It's increasingly common to use products like S3 to host static files, but
        sometimes those static files aren't exactly meant for public eyes.  You might
        push some bit of personal client information into S3 and then anyone with the
        URL will be able to see it.
        
        Sure, the URL may be really hard to guess, but I'm not a fan of "security
        through obscurity" so I wrote this to encrypt stuff I push to S3.  Now, only
        encrypted blobs are available publicly, but internally, behind a
        ``MyPermissionRequiredMixin``, the images and documents are loaded magically
        and transparently.
        
        
        How's It Work?
        --------------
        
        ``EncryptedFileField`` is a thin wrapper around Django's native ``FileField``
        that transparently encrypts whatever the user has uploaded and passes off the
        now encrypted data to whatever storage engine you've specified.  It also
        overrides the ``.url`` value to return a reference to your own view, which does
        the decryption for you on the way back to the user.
        
        So where you may have once had this:
        
        .. code:: python
        
            # my_app/models.py
        
            class MyModel(models.Model):
        
                name = models.CharField(max_length=128)
                attachment = models.FileField(upload_to="attachments")
                image = models.ImageField(
                    upload_to="images",
                    width_field="image_width",
                    height_field="image_height"
                )
                image_width = models.PositiveIntegerField()
                image_height = models.PositiveIntegerField()
        
        All you have to do is change the file fields and you've got encrypted files
        
        .. code:: python
        
            # settings.py
        
            DEFF_SALT = b"The secret key.  This should be long."
            DEFF_PASSWORD = b"The password.  This should be long too."
            DEFF_FETCH_URL_NAME = "whatever-url-name-you-want"
        
        
            # my_app/models.py
        
            from django_encrypted_filefield.fields import (
                EncryptedFileField,
                EncryptedImageField
            )
        
            class MyModel(models.Model):
        
                name = models.CharField(max_length=128)
                attachment = EncryptedFileField(upload_to="attachments")
                image = EncryptedImageField(
                    upload_to="images",
                    width_field="image_width",
                    height_field="image_height"
                )
                image_width = models.PositiveIntegerField()
                image_height = models.PositiveIntegerField()
        
        
            # my_app/views.py
        
            from django.contrib.auth.mixins import AuthMixin
            from django_encrypted_filefield.views import FetchView
        
        
            class MyPermissionRequiredMixin(AuthMixin)
                """
                Your own rules live here
                """
                pass
        
        
            class MyFetchView(MyPermissionRequiredMixin, FetchView):
                pass
        
        
            # my_app/urls.py
        
            from .views import MyFetchView
        
            urlpatterns = [
                # ...
                url(
                    r"^my-fetch-url/(?P<path>.+)",  # up to you, but path is required
                    MyFetchView.as_view(),          # your view, your permissions
                    name=settings.DEFF_FETCH_URL_NAME
                ),
                # ...
            ]
        
        
        Is There a Demo?
        ----------------
        
        There is!  Just check out the code and run the mini django app in the ``demo``
        directory:
        
        .. code:: bash
        
            $ git clone git@github.com:danielquinn/django-encrypted-filefield.git
            $ cd django-encrypted-filefield/demo
            $ ./manage migrate
            $ ./manage.py runserver
        
        ...then open http://localhost:8000 and submit two files via the form.  In this
        case we're using Django's default_storage, but the same logic should apply to
        all storage engines.
        
        You can also run the tests from there:
        
        .. code:: bash
        
            $ ./manage.py test
        
        
        What's the Status of the Project?
        ---------------------------------
        
        Alpha.  I'm actively developing this, so if you find a bug, please let me know.
        If you use it yourself, great!  But if it breaks, you've been warned.
