-"""DES symmetric cipher
-
-DES `(Data Encryption Standard)`__ is a symmetric block cipher standardized
-by NIST_ . It has a fixed data block size of 8 bytes.
-Its keys are 64 bits long, even though 8 bits were used for integrity (now they
-are ignored) and do not contribute to securty.
-
-DES is cryptographically secure, but its key length is too short by nowadays
-standards and it could be brute forced with some effort.
-
-DES should not be used for new designs. Use `AES`.
-
-As an example, encryption can be done as follows:
-
-    >>> from Crypto.Cipher import DES3
-    >>> from Crypto import Random
-    >>>
-    >>> key = b'Sixteen byte key'
-    >>> iv = Random.new().read(DES3.block_size)
-    >>> cipher = DES3.new(key, DES3.MODE_OFB, iv)
-    >>> plaintext = b'sona si latine loqueris '
-    >>> msg = iv + cipher.encrypt(plaintext)

-      key : byte string
-        The secret key to use in the symmetric cipher.
-        It must be 8 byte long. The parity bits will be ignored.
-    :Keywords:
-      mode : a *MODE_** constant
-        The chaining mode to use for encryption or decryption.
-        Default is `MODE_ECB`.
-      IV : byte string
-        The initialization vector to use for encryption or decryption.
-        
-        It is ignored for `MODE_ECB` and `MODE_CTR`.
-
-        For `MODE_OPENPGP`, IV must be `block_size` bytes long for encryption
-        and `block_size` +2 bytes for decryption (in the latter case, it is
-        actually the *encrypted* IV which was prefixed to the ciphertext).
-        It is mandatory.
-       
-        For all other modes, it must be `block_size` bytes longs. It is optional and
-        when not present it will be given a default value of all zeroes.
-      counter : callable
-        (*Only* `MODE_CTR`). A stateful function that returns the next
-        *counter block*, which is a byte string of `block_size` bytes.
-        For better performance, use `Crypto.Util.Counter`.
-      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 0 or not specified, it will be assumed to be 8.
