* Support DH q (subgroup order) * Change RFC5114.txt to NIST format * Add tests for DH q * Update docs for DH q * Fix pep8 * Improve test covergae for DH q * Create _dh_params_dup that copy q if DHparams_dup don't On OpenSSL < 1.0.2 DHparams_dup don't copy q. _dh_params_dup call DHparams_dup and if the version is smaller than 1.0.2 copy q manually * Copy q manually on libressl * Add to test vectors serialized RFC5114 2048 bit DH parameters with 224 bit subgroup * Support serialization of DH with q * Add tests for serialization of DH with q * Support DH serialization with q only if Cryptography_HAS_EVP_PKEY_DHX is true * Raise exception when trying to serialize DH X9.42 when not supported * raise unsupported key type when deserilizing DH X9.42 if not supported * pep8 fixes * Fix test_serialization * Add dhx_serialization_supported method to DHBacked * document q in dh_parameters_supported * Rename dhx_serialization_supported to dh_x942_serialization_supported |

``cryptography`` is a package which provides cryptographic recipes and
primitives to Python developers. Our goal is for it to be your "cryptographic
standard library". It supports Python 2.6-2.7, Python 3.3+, and PyPy 2.6+.
``cryptography`` includes both high level recipes, and low level interfaces to
common cryptographic algorithms such as symmetric ciphers, message digests and
key derivation functions. For example, to encrypt something with
``cryptography``'s high level symmetric encryption recipe:
.. code-block:: pycon
>>> from cryptography.fernet import Fernet
>>> # Put this somewhere safe!
>>> key = Fernet.generate_key()
>>> f = Fernet(key)
>>> token = f.encrypt(b"A really secret message. Not for prying eyes.")
>>> token
'...'
>>> f.decrypt(token)
'A really secret message. Not for prying eyes.'
You can find more information in the `documentation`_.
You can install ``cryptography`` with:
.. code-block:: console
$ pip install cryptography
For full details see `the installation documentation`_.
Discussion
~~~~~~~~~~
If you run into bugs, you can file them in our `issue tracker`_.
We maintain a `cryptography-dev`_ mailing list for development discussion.
You can also join ``#cryptography-dev`` on Freenode to ask questions or get
involved.
