Updated py-cryptography to 1.7.2.

Add more test dependencies.
Self tests cause a python core dump, see
https://github.com/pyca/cryptography/issues/3372

1.7.2 - 2017-01-27
~~~~~~~~~~~~~~~~~~

* Updated Windows and macOS wheels to be compiled against OpenSSL 1.0.2k.

Log message:
Updated py-cryptography to 1.7.1.

1.7.1 - 2016-12-13
~~~~~~~~~~~~~~~~~~

* Fixed a regression in ``int_from_bytes`` where it failed to accept
  ``bytearray``.

1.7 - 2016-12-12
~~~~~~~~~~~~~~~~

* Support for OpenSSL 1.0.0 has been removed. Users on older version of OpenSSL
  will need to upgrade.
* Added support for Diffie-Hellman key exchange using
  \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.dh.DHPrivateKeyWithSerializati \ 
on.exchange`
* The OS random engine for OpenSSL has been rewritten to improve compatibility
  with embedded Python and other edge cases. More information about this change
  can be found in the
  `pull request <https://github.com/pyca/cryptography/pull/3229>`_.

Log message:
Updated py-cryptography to 1.6.

1.6 - 2016-11-22
~~~~~~~~~~~~~~~~

* Deprecated support for OpenSSL 1.0.0. Support will be removed in
  ``cryptography`` 1.7.
* Replaced the Python-based OpenSSL locking callbacks with a C version to fix
  a potential deadlock that could occur if a garbage collection cycle occurred
  while inside the lock.
* Added support for :class:`~cryptography.hazmat.primitives.hashes.BLAKE2b` and
  :class:`~cryptography.hazmat.primitives.hashes.BLAKE2s` when using OpenSSL
  1.1.0.
* Added
  :attr:`~cryptography.x509.Certificate.signature_algorithm_oid` support to
  :class:`~cryptography.x509.Certificate`.
* Added
  :attr:`~cryptography.x509.CertificateSigningRequest.signature_algorithm_oid`
  support to :class:`~cryptography.x509.CertificateSigningRequest`.
* Added
  :attr:`~cryptography.x509.CertificateRevocationList.signature_algorithm_oid`
  support to :class:`~cryptography.x509.CertificateRevocationList`.
* Added support for :class:`~cryptography.hazmat.primitives.kdf.scrypt.Scrypt`
  when using OpenSSL 1.1.0.
* Added a workaround to improve compatibility with Python application bundling
  tools like ``PyInstaller`` and ``cx_freeze``.
* Added support for generating a
  :meth:`~cryptography.x509.random_serial_number`.
* Added support for encoding ``IPv4Network`` and ``IPv6Network`` in X.509
  certificates for use with :class:`~cryptography.x509.NameConstraints`.
* Added :meth:`~cryptography.x509.Name.public_bytes` to
  :class:`~cryptography.x509.Name`.
* Added :class:`~cryptography.x509.RelativeDistinguishedName`
* :class:`~cryptography.x509.DistributionPoint` now accepts
  :class:`~cryptography.x509.RelativeDistinguishedName` for
  :attr:`~cryptography.x509.DistributionPoint.relative_name`.
  Deprecated use of :class:`~cryptography.x509.Name` as
  :attr:`~cryptography.x509.DistributionPoint.relative_name`.
* :class:`~cryptography.x509.Name` now accepts an iterable of
  :class:`~cryptography.x509.RelativeDistinguishedName`.  RDNs can
  be accessed via the :attr:`~cryptography.x509.Name.rdns`
  attribute.  When constructed with an iterable of
  :class:`~cryptography.x509.NameAttribute`, each attribute becomes
  a single-valued RDN.
* Added
  :func:`~cryptography.hazmat.primitives.asymmetric.ec.derive_private_key`.
* Added support for signing and verifying RSA, DSA, and ECDSA signatures with
  :class:`~cryptography.hazmat.primitives.asymmetric.utils.Prehashed`
  digests.

Log message:
Updated py-cryptography to 1.5.3.

1.5.3 - 2016-11-05
~~~~~~~~~~~~~~~~~~

* **SECURITY ISSUE**: Fixed a bug where ``HKDF`` would return an empty
  byte-string if used with a ``length`` less than ``algorithm.digest_size``.
  Credit to **Markus Döring** for reporting the issue.

Log message:
Remove some dead code, python-3.3 is no more.

Log message:
Updated py-cryptography to 1.5.2.

1.5.2 - 2016-09-26
~~~~~~~~~~~~~~~~~~

* Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2j.

Log message:
Updated py-cryptography to 1.5.1.

1.5.1 - 2016-09-22
~~~~~~~~~~~~~~~~~~

* 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.

ld with python-3.x and py-cffi-1.8.x and bump PKGREVISION.

Log message:
Updated py-cryptography to 1.5.

1.5 - 2016-08-26
~~~~~~~~~~~~~~~~

* 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.

Log message:
Updated py-cryptography to 1.4.

1.4 - 2016-06-04
~~~~~~~~~~~~~~~~

* 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 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
