Represents the metadata for a Google Cloud Storage HmacKeyResource.
HMAC keys allow applications to authenticate with Google Cloud Storage using HMAC authentication. Applications can create a limited number of HMAC keys associated with a service account. The application can use the HMAC keys to authenticate with GCS. GCS will use the service account permissions to determine if the request is authorized.
