Installation

$ pip install keep_it_secret

Usage

Keep It Secret gives a developer API needed to declare secrets used by the app and access them in a secure, uniform manner.

Consider the following example:

from secrets_manager import (
    AbstractField, EnvField, LiteralField, Secrets, SecretsField,
)
from secrets_manager.ext.aws import AWSSecrets, AWSSecretsManagerField

class AppSecrets(Secrets):
    secret_key: str = AbstractField.new()
    db_password: str = EnvField.new('APP_DB_PASSWORD', required=True)
    pbkdf2_iterations_count: int = EnvField(
        'APP_PBKDF2_ITERATIONS_COUNT',
        default=16384,
        required=False,
        as_type=int,
    )

class DevelopmentSecrets(AppSecrets):
    secret_key: str = LiteralField.new('thisisntsecure')

class ProductionSecrets(AppSecrets):
    aws: AWSSecrets = SecretsField.new(AWSSecrets)
    secret_key: str = AWSSecretsManagerField(
        'app/production/secret_key', required=True,
    )
    db_password: str = AWSSecretsManagerField(
        'app/production/db_password', required=True,
    )

The AppSecrets class serves as base class for environment specific classes. The environment specific classes can overload any field, add new fields and extend the base class to provide custom behaviour.

The DevelopmentSecrets class uses environment variables and literal values to provide secrets suitable for the development environment:

>>> development_secrets = DevelopmentSecrets()
>>> development_secrets.secret_key
'thisisntsecure'
>>> development_secrets.db_password
'spam'
>>> development_secrets.pbkdf2_iterations_count
1024

The ProductionSecrets class uses environment variables and AWS Secrets Manager to provide secrets suitable for the production environment:

>>> production_secrets = ProductionSecrets()
>>> production_secrets.aws.access_key_id
'anawsaccesskey'
>>> production_secrets.secret_key
'asecuresecretkey'
>>> production_secrets.db_password
'asecuredbpassword'
>>> production_secrets.pbkdf2_iterations_count
16384
