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. )rsysmodules__name__)r modeargskwargss&&*,rnewr$Vs%x #++h/ LT LV LL)__doc__r Crypto.CipherrCrypto.Util.py3compatrCrypto.Util._raw_apirrrrrrrr$MODE_ECBMODE_CBCMODE_CFBMODE_OFBMODE_CTR MODE_OPENPGPMODE_EAX block_sizerangerr%rr4sw,  (-99*-  $64<M|       F r%
