This package allows for encrypting secret strings in python files in a human readable way using type hints. it also supports dynamic loading of python files which contain encrypted strings, providing the password via an environment variable

$ pip install etypes

or

$ poetry add etypes

Define a variable with the type hint DecryptedSecret

from etypes import DecryptedSecret
SECRET_VAR: DecryptedSecret = "some-secret-value"

To encrypt the file, run the following

$ etypes encrypt -p PASSWORD ./path/to/python_file.py

or

$ etypes encrypt -pf ./path/to/password_file ./path/to/python_file.py

results in

from etypes import EncryptedSecret
SECRET_VAR: EncryptedSecret = "gAAAAABmT9yA6HQOXF4BM6gvUG_ryKqrXK9BEgRY2W4lNQvDNBVbiCEOz50-viDLEMXA71upgcGgRbqvC-IAltbjE8w5MbSooJN5EV-8sVe1q3LndfBNzEg="

To decrypt the file run

$ etypes decrypt -p PASSWORD ./path/to/python_file.py

or

$ etypes v -pf ./path/to/password_file ./path/to/python_file.py

To import this python file in your project and have it decrypt itself seamlessly when accessed.

You must import the AutoLoader and configure it to accept a password via a environment variable or to look for a file at a path.

# app/settings/secrets.py

from etypes import EncryptedSecret, AutoLoader
SECRET_VAR: EncryptedSecret = "gAAAAABmT9yA6HQOXF4BM6gvUG_ryKqrXK9BEgRY2W4lNQvDNBVbiCEOz50-viDLEMXA71upgcGgRbqvC-IAltbjE8w5MbSooJN5EV-8sVe1q3LndfBNzEg="

AutoLoader(locals(), password_var_name="SOME_ENV_VAR_WHICH_CONTAINS_PASSWORD")
# or
AutoLoader(locals(), password_file="/path/to/your/secret_file")

import your settings/secrets file normally.

# app/main.py

from .settings import secrets
print(secrets.SECRET_VAR)

Run your application providing the password declaring in your AutoLoader $ SOME_ENV_VAR_WHICH_CONTAINS_PASSWORD="PASSWORD" ./main.py
