# secret-loader
### Load secrets from multiple locations

`secret-loader` provides a `SecretLoader` type that can load a `SecretString`
from an environment variable, a file, or directly as a String. The intended use case is to remove
hard-coded credentials in configuration files and replace them with hints on how an application should
load the secret instead. E.g. updating the following TOML configuration file:
```toml
[user.alice]
username = "alice"
key = "somecrazypassword"

[user.bob]
username = "bob"
key = "hello123"
```
With the following configuration file instead:
```toml
[user.alice]
username = "alice"
key = "env:ALICE_SECRET_KEY"

[user.bob]
username = "bob"
key = "file:/home/bob/.auth_token"
```

## Optional Features
`secret-loader` currently implements the following feature flags:

| Feature Name | Description |
| --- | --- |
| serde | Enable automatic deserialization of a `SecretLoader` |
