 """ Create a new ``CryptoKey`` within a ``KeyRing``. ``CryptoKey.purpose`` and ``CryptoKey.version_template.algorithm`` are required. Example: Args: parent (str):
 Required. The ``name`` of the KeyRing associated with the ``CryptoKeys``. crypto_key_id (str):
 Required. It must be unique within a KeyRing and match the regular expression ``[a-zA-Z0-9_-]{1,63}`` crypto_key (Union[dict, ~google.cloud.kms_v1.types.CryptoKey]):
 A ``CryptoKey`` with initial field values. If a dict is provided, it must be of the same form as the protobuf message :class:`~google.cloud.kms_v1.types.CryptoKey` retry (Optional[google.api_core.retry.Retry]):
 A retry object used to retry requests. If ``None`` is specified, requests will not be retried. timeout (Optional[float]):
 The amount of time, in seconds, to wait for the request to complete. Note that if ``retry`` is specified, the timeout applies to each individual attempt. metadata (Optional[Sequence[Tuple[str, str]]]):
 Additional metadata that is provided to the method. Returns: A :class:`~google.cloud.kms_v1.types.CryptoKey` instance. Raises: google.api_core.exceptions.GoogleAPICallError: If the request failed for any reason. google.api_core.exceptions.RetryError: If the request failed due to a retryable error and retry attempts failed. ValueError: If the parameters are invalid. """
