Python module for encrypting and decryting .env files.

This module can be installed with pythons setuptools. It is not currently in pypi, so just run setup.py locally:

python setup.py install

After running the setup.py script, a cli tool called env-crypt is installed. This tool can be used to:

Encrypt the .env file with a password:

>>> env-crypt --env-path $PATH_TO_DOTENV --password $YOUR_PASSWORD encrypt

Decrypt the .env file with a password:

>>> env-crypt --env-path $PATH_TO_DOTENV --password $YOUR_PASSWORD decrypt

Encrypt the .env file with a keyfile:

>>> env-crypt --env-path $PATH_TO_DOTENV --keyfile $PATH_TO_SECRET_FILE encrypt

Decrypt the .env file with a keyfile:

>>> env-crypt --env-path $PATH_TO_DOTENV --keyfile $PATH_TO_SECRET_FILE decrypt

You can update the value of an encrypted .env key without having to decrypt it first:

>>> env-crypt --env-path $PATH_TO_DOTENV --password $YOUR_PASSWORD update --key $KEY_TO_UPDATE --value $NEW_VALUE

You can see what the current values in the .env file are without having to decrypt and re-encrypt the files

>>> env-crypt --env-path $PATH_TO_DOTENV --keyfile $PATH_TO_SECRET_FILE list

Once you have encrypted your env file, you can load it into the python environment by importing the module:

import os
from env_crypt import load_env

load_env('path/to/.env', password='your password',
keyfile='path/to/keyfile')

# Access the env value as normal, it will be decrypted for use
os.environ[key]
