def increase_crypto_config(self, crypto_adapters,
                               crypto_domain_configurations):
        """
        Add crypto adapters and/or crypto domains to the crypto configuration
        of this partition.

        The general principle for maintaining crypto configurations of
        partitions is as follows: Each adapter included in the crypto
        configuration of a partition has all crypto domains included in the
        crypto configuration. Each crypto domain included in the crypto
        configuration has the same access mode on all adapters included in the
        crypto configuration.

        Example: Assume that the current crypto configuration of a partition
        includes crypto adapter A and crypto domains 0 and 1. When this method
        is called to add adapter B and domain configurations for domains 1 and
        2, the resulting crypto configuration of the partition will include
        domains 0, 1, and 2 on each of the adapters A and B.

        Authorization requirements:

        * Object-access permission to this Partition.
        * Task permission to the "Partition Details" task.

        Parameters:

          crypto_adapters (:term:`iterable` of :class:`~zhmcclient.Adapter`):
            Crypto adapters that should be added to the crypto configuration of
            this partition.

          crypto_domain_configurations (:term:`iterable` of `domain_config`):
            Crypto domain configurations that should be added to the crypto
            configuration of this partition.

            A crypto domain configuration (`domain_config`) is a dictionary
            with the following keys:

            * ``"domain-index"`` (:term:`integer`): Domain index of the crypto
              domain.

              The domain index is a number in the range of 0 to a maximum that
              depends on the model of the crypto adapter and the CPC model. For
              the Crypto Express 5S adapter in a z13, the maximum domain index
              is 84.

            * ``"access-mode"`` (:term:`string`): Access mode for the crypto
              domain.

              The access mode specifies the way the partition can use the
              crypto domain on the crypto adapter(s), using one of the
              following string values:

              * ``"control"`` - The partition can load cryptographic keys into
                the domain, but it may not use the domain to perform
                cryptographic operations.

              * ``"control-usage"`` - The partition can load cryptographic keys
                into the domain, and it can use the domain to perform
                cryptographic operations.

        Raises:

          :exc:`~zhmcclient.HTTPError`
          :exc:`~zhmcclient.ParseError`
          :exc:`~zhmcclient.AuthError`
