      # An ImportJob can be used to create CryptoKeys and CryptoKeyVersions using pre-

      # key pair. You use the wrapping key to encrypt (also known as wrap) the pre-
      # existing key material to protect it during the import process. The nature of
      # the wrapping key depends on the choice of import_method. When the wrapping key
      # generation is complete, the state will be set to ACTIVE and the public_key can
      # be fetched. The fetched public key can then be used to wrap your pre-existing
      # key material. Once the key material is wrapped, it can be imported into a new
      # CryptoKeyVersion in an existing CryptoKey by calling ImportCryptoKeyVersion.
      # Multiple CryptoKeyVersions can be imported with a single ImportJob. Cloud KMS
