    """Create a new CAST cipher
    :param key:
        The secret key to use in the symmetric cipher.
        Its length can vary from 5 to 16 bytes.
    :type key: bytes, bytearray, memoryview
    :param mode:
        The chaining mode to use for encryption or decryption.
    :type mode: One of the supported ``MODE_*`` constants
    :Keyword Arguments:
        *   **iv** (*bytes*, *bytearray*, *memoryview*) --
            (Only applicable for ``MODE_CBC``, ``MODE_CFB``, ``MODE_OFB``,
            and ``MODE_OPENPGP`` modes).
            The initialization vector to use for encryption or decryption.
            For ``MODE_CBC``, ``MODE_CFB``, and ``MODE_OFB`` it must be 8 bytes long.
            For ``MODE_OPENPGP`` mode only,
            it must be 8 bytes long for encryption
            and 10 bytes for decryption (in the latter case, it is
            actually the *encrypted* IV which was prefixed to the ciphertext).
            If not provided, a random byte string is generated (you must then
            read its value with the :attr:`iv` attribute).
        *   **nonce** (*bytes*, *bytearray*, *memoryview*) --
            (Only applicable for ``MODE_EAX`` and ``MODE_CTR``).
            A value that must never be reused for any other encryption done
            with this key.
            For ``MODE_EAX`` there are no
            restrictions on its length (recommended: **16** bytes).
            For ``MODE_CTR``, its length must be in the range **[0..7]**.
            If not provided for ``MODE_EAX``, a random byte string is generated (you
            can read it back via the ``nonce`` attribute).
        *   **segment_size** (*integer*) --
            (Only ``MODE_CFB``).The number of **bits** the plaintext and ciphertext
            are segmented in. It must be a multiple of 8.
            If not specified, it will be assumed to be 8.
        *   **mac_len** : (*integer*) --
            (Only ``MODE_EAX``)
            Length of the authentication tag, in bytes.
            It must be no longer than 8 (default).
        *   **initial_value** : (*integer*) --
            (Only ``MODE_CTR``). The initial value for the counter within
            the counter block. By default it is **0**.
    :Return: a CAST object, of the applicable mode.
