        Args:

                of the [ImportJob][google.cloud.kms.v1.ImportJob] to

                This corresponds to the ``name`` field

            metadata (Sequence[Tuple[str, str]]): Strings which should be
                sent along with the request as metadata.

        Returns:
            google.cloud.kms_v1.types.ImportJob:
                An [ImportJob][google.cloud.kms.v1.ImportJob] can be used to create [CryptoKeys][google.cloud.kms.v1.CryptoKey] and
                   [CryptoKeyVersions][google.cloud.kms.v1.CryptoKeyVersion]
                   using pre-existing key material, generated outside of
                   Cloud KMS.

                   When an [ImportJob][google.cloud.kms.v1.ImportJob] is
                   created, Cloud KMS will generate a "wrapping key",
                   which is a public/private 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][google.cloud.kms.v1.ImportJob.import_method].
                   When the wrapping key generation is complete, the
                   [state][google.cloud.kms.v1.ImportJob.state] will be
                   set to
                   [ACTIVE][google.cloud.kms.v1.ImportJob.ImportJobState.ACTIVE]
                   and the
                   [public_key][google.cloud.kms.v1.ImportJob.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][google.cloud.kms.v1.CryptoKeyVersion]
                   in an existing
                   [CryptoKey][google.cloud.kms.v1.CryptoKey] by calling
                   [ImportCryptoKeyVersion][google.cloud.kms.v1.KeyManagementService.ImportCryptoKeyVersion].
                   Multiple
                   [CryptoKeyVersions][google.cloud.kms.v1.CryptoKeyVersion]
                   can be imported with a single
                   [ImportJob][google.cloud.kms.v1.ImportJob]. Cloud KMS
                   uses the private key portion of the wrapping key to
                   unwrap the key material. Only Cloud KMS has access to
                   the private key.

                   An [ImportJob][google.cloud.kms.v1.ImportJob] expires
                   3 days after it is created. Once expired, Cloud KMS
                   will no longer be able to import or unwrap any key
                   material that was wrapped with the
                   [ImportJob][google.cloud.kms.v1.ImportJob]'s public
                   key.

                An [ImportJob][google.cloud.kms.v1.ImportJob] can be used to create [CryptoKeys][google.cloud.kms.v1.CryptoKey] and
                   [CryptoKeyVersions][google.cloud.kms.v1.CryptoKeyVersion]
                   using pre-existing key material, generated outside of
                   Cloud KMS.

                   When an [ImportJob][google.cloud.kms.v1.ImportJob] is
                   created, Cloud KMS will generate a "wrapping key",
                   which is a public/private 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][google.cloud.kms.v1.ImportJob.import_method].
                   When the wrapping key generation is complete, the
                   [state][google.cloud.kms.v1.ImportJob.state] will be
                   set to
                   [ACTIVE][google.cloud.kms.v1.ImportJob.ImportJobState.ACTIVE]
                   and the
                   [public_key][google.cloud.kms.v1.ImportJob.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][google.cloud.kms.v1.CryptoKeyVersion]
                   in an existing
                   [CryptoKey][google.cloud.kms.v1.CryptoKey] by calling
                   [ImportCryptoKeyVersion][google.cloud.kms.v1.KeyManagementService.ImportCryptoKeyVersion].
                   Multiple
                   [CryptoKeyVersions][google.cloud.kms.v1.CryptoKeyVersion]
                   can be imported with a single
                   [ImportJob][google.cloud.kms.v1.ImportJob]. Cloud KMS
                   uses the private key portion of the wrapping key to
                   unwrap the key material. Only Cloud KMS has access to
                   the private key.

                   An [ImportJob][google.cloud.kms.v1.ImportJob] expires
                   3 days after it is created. Once expired, Cloud KMS
                   will no longer be able to import or unwrap any key
                   material that was wrapped with the
                   [ImportJob][google.cloud.kms.v1.ImportJob]'s public
                   key.

                accounts, Google groups, and domains (such as G Suite).
                A ``role`` is a named list of permissions (defined by
                IAM or configured by users). A ``binding`` can
                optionally specify a ``condition``, which is a logic
                expression that further constrains the role binding
                based on attributes about the request and/or target
                resource.

                Defines an Identity and Access Management (IAM) policy.
                It is used to specify access control policies for Cloud
                Platform resources.
                A ``Policy`` is a collection of ``bindings``. A
                ``binding`` binds one or more ``members`` to a single
                ``role``. Members can be user accounts, service
                accounts, Google groups, and domains (such as G Suite).
                A ``role`` is a named list of permissions (defined by
                IAM or configured by users). A ``binding`` can
                optionally specify a ``condition``, which is a logic
                expression that further constrains the role binding
                based on attributes about the request and/or target
                resource.
