/*
Key Store Port
A port that defines how the application stores and validates keys. This is a
a secure system such as a key management service, a hardware
security module, or any other secure key storage mechanism.
The key store port is responsible for providing an abstraction layer that allows the application
to securely store and validate keys without being tightly coupled to the details of how those keys
are stored and retrieved. This way a centralized storage mechanism can be used to manage keys
across the application and other applications.
A typical implementation of this port would be for the adapter to translate key storage
and validation requests from the application into calls to the key storage mechanism, and to
translate responses from the key storage mechanism back into a format
that the application can use.
Configuration of the environment and access control to the key store would be managed by the
infrastructue config and security mechanisms.
