+
+        For ``MODE_SIV`` only, it doubles to 32, 48, or 64 bytes.
+      mode (a ``MODE_*`` constant):
+        The chaining mode to use for encryption or decryption.
+        If in doubt, use ``MODE_EAX``.
+
+    Keyword Args:
+      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 16 bytes long.
+
+        For ``MODE_OPENPGP`` mode only,
+        it must be 16 bytes long for encryption
+        and 18 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_CCM``, ``MODE_EAX``, ``MODE_GCM``,
+        ``MODE_SIV``, ``MODE_OCB``, and ``MODE_CTR``).
+
+        A value that must never be reused for any other encryption done
+        with this key (except possibly for ``MODE_SIV``, see below).
+
+        For ``MODE_EAX``, ``MODE_GCM`` and ``MODE_SIV`` there are no
+        restrictions on its length (recommended: **16** bytes).
+
+        For ``MODE_CCM``, its length must be in the range **[7..13]**.
+        Bear in mind that with CCM there is a trade-off between nonce
+        length and maximum message size. Recommendation: **11** bytes.
+
+        For ``MODE_OCB``, its length must be in the range **[1..15]**
+        (recommended: **15**).
+
+        For ``MODE_CTR``, its length must be in the range **[0..15]**
+        (recommended: **8**).
+
+        For ``MODE_SIV``, the nonce is optional, if it is not specified,
+        then no nonce is being used, which renders the encryption
+        deterministic.
+
+        If not provided, for modes other than ``MODE_SIV``, a random
+        byte string of the recommended length is used (you must then
+        read its value with the :attr:`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``, ``MODE_GCM``, ``MODE_OCB``, ``MODE_CCM``)
+        Length of the authentication tag, in bytes.
+
+        It must be even and in the range **[4..16]**.
+        The recommended value (and the default, if not specified) is **16**.
+
+      msg_len (integer):
+        (Only ``MODE_CCM``). Length of the message to (de)cipher.
+        If not specified, ``encrypt`` must be called with the entire message.
+        Similarly, ``decrypt`` can only be called once.
+
+      assoc_len (integer):
+        (Only ``MODE_CCM``). Length of the associated data.
+        If not specified, all associated data is buffered internally,
+        which may represent a problem for very large messages.
+
+      initial_value (integer or bytes/bytearray/memoryview):
+        (Only ``MODE_CTR``).
+        The initial value for the counter. If not present, the cipher will
+        start counting from 0. The value is incremented by one for each block.
+        The counter number is encoded in big endian mode.
+
+      counter (object):
+        (Only ``MODE_CTR``).
+        Instance of ``Crypto.Util.Counter``, which allows full customization
+        of the counter block. This parameter is incompatible to both ``nonce``
+        and ``initial_value``.
+
+      use_aesni: (boolean):

+

+Offset Codebook (OCB) mode.
+
+OCB is Authenticated Encryption with Associated Data (AEAD) cipher mode
+designed by Prof. Phillip Rogaway and specified in `RFC7253`_.
+
+The algorithm provides both authenticity and privacy, it is very efficient,
+it uses only one key and it can be used in online mode (so that encryption
+or decryption can start before the end of the message is available).
+
+This module implements the third and last variant of OCB (OCB3) and it only
+works in combination with a 128-bit block symmetric cipher, like AES.
+
+OCB is patented in US but `free licenses`_ exist for software implementations
+meant for non-military purposes.
+
+Example:
+    >>> from Crypto.Cipher import AES
+    >>> from Crypto.Random import get_random_bytes
+    >>>
+    >>> key = get_random_bytes(32)
+    >>> cipher = AES.new(key, AES.MODE_OCB)
+    >>> plaintext = b"Attack at dawn"
+    >>> ciphertext, mac = cipher.encrypt_and_digest(plaintext)
+    >>> # Deliver cipher.nonce, ciphertext and mac
+    ...
+    >>> cipher = AES.new(key, AES.MODE_OCB, nonce=nonce)
+    >>> try:
+    >>>     plaintext = cipher.decrypt_and_verify(ciphertext, mac)
+    >>> except ValueError:
+    >>>     print "Invalid message"
+    >>> else:
+    >>>     print plaintext
