PACKAGE_DESCRIPTION = """
# 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. **NOTE:
   This is barely supported.** Requires `hvac` python package.

## Future extensions

- [ ] Key casing should be more consistent
    * Case-insensitive for hardcoded and `load`.
    * Upper case for environment variables.
    * Lower case for files and others.
- [ ] New special configuration value for switching the `secrets` directory.
- [ ] 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.
- [ ] 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)?§
- [ ] Vault:
  * [ ] Ensure vault code path works.
  * [ ] Document usage and requirements.
