+ Args:
+ key(bytes/bytearray/memoryview):
+ The secret key to use in the symmetric cipher.
+
+ It must be 16 (*AES-128)*, 24 (*AES-192*) or 32 (*AES-256*) bytes long.
+
+ 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,

+ **Use PKCS#1 OAEP instead**.
+
+ This implementation attempts to mitigate the risk

+ implement and the way you handle errors make a big difference.

+ Specifically, you should make it very hard for the (malicious)
+ party that submitted the ciphertext to quickly understand if decryption
+ succeeded or not.
+
+ To this end, it is recommended that your protocol only encrypts
+ plaintexts of fixed length (``expected_pt_len``),
+ that ``sentinel`` is a random byte string of the same length,
+ and that processing continues for as long
+ as possible even if ``sentinel`` is returned (i.e. in case of

+ This is an Authenticated Encryption with Associated Data (`AEAD`_) mode.
+ It provides both confidentiality and authenticity.
+
+ The header of the message may be left in the clear, if needed, and it will
+ still be subject to authentication. The decryption step tells the receiver
+ if the message comes from a source that really knowns the secret key.
+ Additionally, decryption detects if any part of the message - including the
+ header - has been modified or corrupted.
+
+ This mode requires a nonce. The nonce shall never repeat for two
+ different messages encrypted with the same key, but it does not need
+ to be random.
+ Note that there is a trade-off between the size of the nonce and the
+ maximum size of a single message you can encrypt.
+
+ It is important to use a large nonce if the key is reused across several
+ messages and the nonce is chosen randomly.
+
+ It is acceptable to us a short nonce if the key is only used a few times or
+ if the nonce is taken from a counter.
+
+ The following table shows the trade-off when the nonce is chosen at
+ random. The column on the left shows how many messages it takes
+ for the keystream to repeat **on average**. In practice, you will want to
+ stop using the key way before that.

+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

+
+ This is an Authenticated Encryption with Associated Data (`AEAD`_) mode.
+ It provides both confidentiality and authenticity.
+
+ The header of the message may be left in the clear, if needed, and it will
+ still be subject to authentication. The decryption step tells the receiver
+ if the message comes from a source that really knowns the secret key.
+ Additionally, decryption detects if any part of the message - including the
+ header - has been modified or corrupted.
+
+ Unlike other AEAD modes such as CCM, EAX or GCM, accidental reuse of a
+ nonce is not catastrophic for the confidentiality of the message. The only
+ effect is that an attacker can tell when the same plaintext (and same
+ associated data) is protected with the same key.
+
+ The length of the MAC is fixed to the block size of the underlying cipher.
+ The key size is twice the length of the key of the underlying cipher.
+
+ This mode is only available for AES ciphers.

+
+ pkcs (integer):
+ (*Private keys only*) The standard to use for
+ serializing the key: PKCS#1 or PKCS#8.
+
+ With ``pkcs=1`` (*default*), the private key is encoded with a
+ simple `PKCS#1`_ structure (``RSAPrivateKey``). The key cannot be

+
+ You can only specify a value if ``pkcs=8``.
+ For all possible protection schemes,
+ refer to :ref:`the encryption parameters of PKCS#8<enc_params>`.
+ The recommended value is
+ ``'PBKDF2WithHMAC-SHA512AndAES256-CBC'``.
+
+ If ``None`` (default), the behavior depends on :attr:`format`:
+
+ - if ``format='PEM'``, the obsolete PEM encryption scheme is used.
+ It is based on MD5 for key derivation, and 3DES for encryption.

+ - if ``format='DER'``, the ``'PBKDF2WithHMAC-SHA1AndDES-EDE3-CBC'``

+ prot_params (dict):
+ (*For private keys only*)
+
+ The parameters to use to derive the encryption key
+ from the passphrase. ``'protection'`` must be also specified.
+ For all possible values,
+ refer to :ref:`the encryption parameters of PKCS#8<enc_params>`.
+ The recommendation is to use ``{'iteration_count':21000}`` for PBKDF2,

+# - oid an ASCII string with the registered ASN.1 Object ID
+# - context a raw pointer to memory holding a context for all curve operations (can be None)
+# - canonical the canonical name of the curve
+# - openssh the ASCII string used in OpenSSH id files for public keys on this curve
+# - rawlib the reference to the dynamic libary with the low-level functions

+ ABSTRACT
+ --------
+
+ We present a simple way to test the correctness of a DES implementation:
+ Use the recurrence relation:
+
+ X0 = 9474B8E8C73BCA7D (hexadecimal)
+
+ X(i+1) = IF (i is even) THEN E(Xi,Xi) ELSE D(Xi,Xi)
+
+ to compute a sequence of 64-bit values: X0, X1, X2, ..., X16. Here
+ E(X,K) denotes the DES encryption of X using key K, and D(X,K) denotes
+ the DES decryption of X using key K. If you obtain
+
+ X16 = 1B1A2DDB4C642438
+
+ your implementation does not have any of the 36,568 possible single-fault

+"""Compatibility code for handling string/bytes changes from Python 2.x to Py3k
+
+In Python 2.x, strings (of type ''str'') contain binary data, including encoded
+Unicode text (e.g. UTF-8). The separate type ''unicode'' holds Unicode text.
+Unicode literals are specified via the u'...' prefix. Indexing or slicing
+either type always produces a string of the same type as the original.
+Data read from a file is always of '''str'' type.
+
+In Python 3.x, strings (type ''str'') may only contain Unicode text. The u'...'
+prefix and the ''unicode'' type are now redundant. A new type (called
+''bytes'') has to be used for binary data (including any particular
+''encoding'' of a string). The b'...' prefix allows one to specify a binary
+literal. Indexing or slicing a string produces another string. Slicing a byte
+string produces another byte string, but the indexing operation produces an
+integer. Data read from a file is of '''str'' type if the file was opened in
+text mode, or of ''bytes'' type otherwise.
+
+Since PyCrypto aims at supporting both Python 2.x and 3.x, the following helper
+functions are used to keep the rest of the library as independent as possible
+from the actual Python version.
+
+In general, the code should always deal with binary strings, and use integers
+instead of 1-byte character strings.
+
+b(s)
+ Take a text string literal (with no prefix or with u'...' prefix) and
+ make a byte string.
+bchr(c)
+ Take an integer and make a 1-character byte string.
+bord(c)
+ Take the result of indexing on a byte string and make an integer.
+tobytes(s)
+ Take a text string, a byte string, or a sequence of character taken from
+ a byte string and make a byte string.

+PyCryptodome
+============
+
+PyCryptodome is a self-contained Python package of low-level
+cryptographic primitives.
+
+It supports Python 2.7, Python 3.7 and newer, and PyPy.
+
+You can install it with::
+
+ pip install pycryptodome
+
+All modules are installed under the ``Crypto`` package.
+
+Check the pycryptodomex_ project for the equivalent library that
+works under the ``Cryptodome`` package.
+
+PyCryptodome is a fork of PyCrypto. It brings several enhancements
+with respect to the last official version of PyCrypto (2.6.1),
+for instance:
+
+* Authenticated encryption modes (GCM, CCM, EAX, SIV, OCB, KW, KWP)
+* Hybrid Public Key Encryption (HPKE)
+* Accelerated AES on Intel platforms via AES-NI
+* First class support for PyPy
+* Elliptic curves cryptography (NIST P-curves; Ed25519, Ed448, Curve25519)
+* Better and more compact API (`nonce` and `iv` attributes for ciphers,
+ automatic generation of random nonces and IVs, simplified CTR cipher mode,
+ and more)
+* SHA-3 (including SHAKE XOFs) and BLAKE2 hash algorithms
+* Salsa20 and ChaCha20 stream ciphers
+* scrypt and HKDF
+* Deterministic (EC)DSA and EdDSA
+* Password-protected PKCS#8 key containers
+* Shamir's Secret Sharing scheme
+* Random numbers get sourced directly from the OS (and not from a CSPRNG in userspace)
+* Simplified install process, including better support for Windows
+* Cleaner RSA and DSA key generation (largely based on FIPS 186-4)
+* Major clean ups and simplification of the code base
+
+PyCryptodome is not a wrapper to a separate C library like *OpenSSL*.
+To the largest possible extent, algorithms are implemented in pure Python.
+Only the pieces that are extremely critical to performance (e.g. block ciphers)
+are implemented as C extensions.
+
+For more information, see the `homepage`_.
+
+All the code can be downloaded from `GitHub`_.
