DJANGO OUTBOX ENCRYPTION

DJANGO OUTBOX ENCRYPTION

Sometimes, when you ready to publish your project to server.

There is a slight change between the application settings on the local and the server. Such as database name, password, etc. The second thing, is you need to encrypt information like password or other. The last one, you need to automatically select setting local when you work on local computer, and auto select server when application running on server.

You are on the right path...

Install package to your environment

> pip install outbox-encryption

How it works

On developing time, library will scan your environment variable
to get file name specific for you computer, for example : .env-outbox-python
this file must exists on your source code to make application continue.

On deploy time, for example your local computer, library again will scan your
environment variable and get file name base on computer where it running

if file found, application continue, else stop application

if you ready to deploy to server, just rename file .env-outbox-python to name 
which is must be found on server

How to use

Create Encrypt File

> python manage.py shell

> from encryption import OutboxEncryption
> lib = OutboxEncryption()
> mplaint_text = {
        'DB_PASSWORD': '',
        'SECRET_KEY': 'xxg_7me8rl2m#a_h2oresgt2#ni=3_4*!ai*=rtsq)yi!g7_5-51xx'
    }
> lib.enc_environ(mplaint_text)
# new file is created (maybe file is hidden, CTRL+H to show it)

# Open file .env.local
    You have to write other setting that no encrypt apply, such as:
    DEBUG=True
    UNDER_CONSTRUCTION=False
    DB_ENGINE=django.db.backends.mysql
    DB_NAME=db_name
    DB_USER=root
    DB_HOST=127.0.0.1
    DB_PORT=3306

Note:

File name auto create base on environment variable on running computer.
If run on server just rename this file, and write setting needed to run website on server

Decrypt environment file

> python manage.py shell

> from encryption import OutboxEncryption
> lib = OutboxEncryption()

> mplaint_key = {
    'DB_PASSWORD',
    'SECRET_KEY'
    }
> mplaint_list = {
    'ALLOWED_HOSTS',
    'CSRF_TRUSTED_ORIGINS'
    }
> key = lib.dec_environ(mplaint_key, mplaint_list)
> print (key)

Change your settings.py file

Run inside settings.py (django project settings)            
> from encryption import OutboxEncryption
> lib = OutboxEncryption()

# List of key variable that must be encrypt or decrypt before set or get data
> mplaint_key = ['DB_PASSWORD', 'SECRET_KEY']

Variable that must be cast as list from environmnet to settings.py
> mplaint_list = ['ALLOWED_HOSTS', 'CSRF_TRUSTED_ORIGINS']

Variable that must be cast as tuple from environment to settings.py
> mplaint_tuple = ['SECURE_PROXY_SSL_HEADER']

Get encryption data
> key = lib.decrypt_environ(mplaint_key, mplaint_list, mplaint_tuple)

Setting variable :
> DEBUG = key['DEBUG']
> UNDER_CONSTRUCTION = key['UNDER_CONSTRUCTION']
> DEBUG = key['DEBUG']
> SECRET_KEY = key['SECRET_KEY']
> ALLOWED_HOSTS = key['ALLOWED_HOSTS']

> tmp_engine = key['DB_ENGINE']
> if 'sqlite3' in tmp_engine:
    DATABASES = {
        'default': {
            'ENGINE': tmp_engine,                
            'NAME': key['DB_NAME'],   # Path lengkap
        }
    }
> else: # default 
>   DATABASES = {
        'default': {
            'ENGINE'    : key['DB_ENGINE'],
            'NAME'      : key['DB_NAME'],
            'USER'      : key['DB_USER'],
            'PASSWORD'  : key['DB_PASSWORD'],
            'HOST'      : key['DB_HOST'],
            'PORT'      : key['DB_PORT'],
        }

> SECURE_PROXY_SSL_HEADER = key['SECURE_PROXY_SSL_HEADER']

# Optional:
> tmp = key.get('CSRF_TRUSTED_ORIGINS') 
> if tmp:
>   CSRF_TRUSTED_ORIGINS=key['CSRF_TRUSTED_ORIGINS']

# # use default value if setting not exists
> tmp = key.get('STATIC_ROOT')  # True if exists, None if not exists
> STATIC_ROOT = key['STATIC_ROOT'] if tmp else os.path.join(BASE_DIR, 'staticfiles')

> tmp = key.get('MEDIA_ROOT')
> MEDIA_ROOT = key['MEDIA_ROOT'] if tmp else os.path.join(BASE_DIR, 'media')
