Cryptography

~~~~~~~~~~~~~~~~~~

* Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2i.
* Resolved a ``UserWarning`` when used with cffi 1.8.3.
* Fixed a memory leak in name creation with X.509.
* Added a workaround for old versions of setuptools.
* Fixed an issue preventing ``cryptography`` from compiling against
OpenSSL 1.0.2i.



.. _v1-5:

~~~~~~~~~~~~~~~~

* Added
:func:`~cryptography.hazmat.primitives.asymmetric.padding.calculate_max_pss_salt_length`.
* Added "one shot"
:meth:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey.sign`
and
:meth:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey.verify`
methods to DSA keys.
* Added "one shot"
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey.sign`
and
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.verify`
methods to ECDSA keys.
* Switched back to the older callback model on Python 3.5 in order to mitigate
the locking callback problem with OpenSSL <1.1.0.
* :class:`~cryptography.x509.CertificateBuilder`,
:class:`~cryptography.x509.CertificateRevocationListBuilder`, and
:class:`~cryptography.x509.RevokedCertificateBuilder` now accept timezone
aware ``datetime`` objects as method arguments
* ``cryptography`` now supports OpenSSL 1.1.0 as a compilation target.



.. _v1-4:

~~~~~~~~~~~~~~~~

* Support for OpenSSL 0.9.8 has been removed. Users on older versions of
OpenSSL will need to upgrade.
* Added :class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFHMAC`.
* Added support for ``OpenSSH`` public key serialization.
* Added support for SHA-2 in RSA
:class:`~cryptography.hazmat.primitives.asymmetric.padding.OAEP` when using
OpenSSL 1.0.2 or greater.
* Added "one shot"
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey.sign`
and
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.verify`
methods to RSA keys.
* Deprecated the ``serial`` attribute on
:class:`~cryptography.x509.Certificate`, in favor of
:attr:`~cryptography.x509.Certificate.serial_number`.



.. _v1-3-4:

~~~~~~~~~~~~~~~~~~

* Added another OpenSSL function to the bindings to support an upcoming
``pyOpenSSL`` release.



.. _v1-3-3:

~~~~~~~~~~~~~~~~~~

* Added two new OpenSSL functions to the bindings to support an upcoming
``pyOpenSSL`` release.


.. _v1-3-2:

~~~~~~~~~~~~~~~~~~

* Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2h.
* Fixed an issue preventing ``cryptography`` from compiling against
LibreSSL 2.3.x.


.. _v1-3-1:
