KeyLocator (Keycloak Docs Distribution 21.0.1 API)

All Known Implementing Classes:

CompositeKeyLocator, HardcodedKeyLocator
```
public interface KeyLocator
```
This interface defines a method for obtaining a security key by ID.
If the KeyLocator implementor wants to make all its keys available for iteration, it should implement Iterable<T extends Key> interface. The base KeyLocator does not extend this interface to enable KeyLocators that do not support listing their keys.
