# Secret Loader System. System for loading secrets from a variety of sources. Usage: ```python import secret_loader secrets = secret_loader.SecretLoader(env_key_prefix = 'MYAPP') db_username = secrets.load_or_fail('DATABASE_USERNAME') db_password = secrets.load_or_fail('DATABASE_PASSWORD') ``` Secret loading order: 0. Hardcoded values. **This is purely for debugging, prototyping, and for configuring below options.** 1. Files pointed to by environment variables. Docker friendly. 2. Secrets folder. Also Docker friendly. 3. [Pass: the standard unix password manager](https://www.passwordstore.org/). Most suited for personal usage; very unsuited for server environments. Requires `pass` installed locally, and configuration of the `PASS_STORE_SUBFOLDER` through one of the above methods. 4. Vault instance if configured. Suited for production environments. ## TODO - [ ] Avoid leakage to swap files. * Possibly Mlock? [Does not seem to work](https://stackoverflow.com/questions/29524020/prevent-ram-from-paging-to-swap-area-mlock) * Alternatively use [mmap](https://docs.python.org/3/library/mmap.html) and [memoryview](https://stackoverflow.com/questions/18655648/what-exactly-is-the-point-of-memoryview-in-python)?§ - [ ] Wrap secrets in intelligent strings: * Instead of returning None on unloaded, return UnknownSecret, that produce error when formatted. * `repr(secret)` should not include contents, but only the secret and how it was loaded. * Methods on `Secret` should be kept minimal. - [ ] Vault: * [ ] Ensure vault code path works. * [ ] Document usage and requirements. ## License Copyright 2024 Jon Michael Aanes.
