Update py-cryptography to 1.2.3:

1.2.3 - 2016-03-01
~~~~~~~~~~~~~~~~~~

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

Log message:
Update py-cryptography to 1.2.2:

1.2.2 - 2016-01-29
~~~~~~~~~~~~~~~~~~

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

Log message:
Update py-cryptography to 1.2.1:

1.2.1 - 2016-01-08
~~~~~~~~~~~~~~~~~~

* Reverts a change to an OpenSSL ``EVP_PKEY`` object that caused errors with
  ``pyOpenSSL``.

1.2 - 2016-01-08
~~~~~~~~~~~~~~~~

* **BACKWARDS INCOMPATIBLE:**
  :class:`~cryptography.x509.RevokedCertificate`
  :attr:`~cryptography.x509.RevokedCertificate.extensions` now uses extension
  classes rather than returning raw values inside the
  :class:`~cryptography.x509.Extension`
  :attr:`~cryptography.x509.Extension.value`. The new classes
  are:

  * :class:`~cryptography.x509.CertificateIssuer`
  * :class:`~cryptography.x509.CRLReason`
  * :class:`~cryptography.x509.InvalidityDate`
* Deprecated support for OpenSSL 0.9.8 and 1.0.0. At this time there is no time
  table for actually dropping support, however we strongly encourage all users
  to upgrade, as those versions no longer receives support from the OpenSSL
  project.
* The :class:`~cryptography.x509.Certificate` class now has
  :attr:`~cryptography.x509.Certificate.signature` and
  :attr:`~cryptography.x509.Certificate.tbs_certificate_bytes` attributes.
* The :class:`~cryptography.x509.CertificateSigningRequest` class now has
  :attr:`~cryptography.x509.CertificateSigningRequest.signature` and
  :attr:`~cryptography.x509.CertificateSigningRequest.tbs_certrequest_bytes`
  attributes.
* The :class:`~cryptography.x509.CertificateRevocationList` class now has
  :attr:`~cryptography.x509.CertificateRevocationList.signature` and
  :attr:`~cryptography.x509.CertificateRevocationList.tbs_certlist_bytes`
  attributes.
* :class:`~cryptography.x509.NameConstraints` are now supported in the
  :class:`~cryptography.x509.CertificateBuilder` and
  :class:`~cryptography.x509.CertificateSigningRequestBuilder`.
* Support serialization of certificate revocation lists using the
  :meth:`~cryptography.x509.CertificateRevocationList.public_bytes` method of
  :class:`~cryptography.x509.CertificateRevocationList`.
* Add support for parsing :class:`~cryptography.x509.CertificateRevocationList`
  :meth:`~cryptography.x509.CertificateRevocationList.extensions` in the
  OpenSSL backend. The following extensions are currently supported:

  * :class:`~cryptography.x509.AuthorityInformationAccess`
  * :class:`~cryptography.x509.AuthorityKeyIdentifier`
  * :class:`~cryptography.x509.CRLNumber`
  * :class:`~cryptography.x509.IssuerAlternativeName`
* Added :class:`~cryptography.x509.CertificateRevocationListBuilder` and
  :class:`~cryptography.x509.RevokedCertificateBuilder` to allow creation of
  CRLs.
* Unrecognized non-critical X.509 extensions are now parsed into an
  :class:`~cryptography.x509.UnrecognizedExtension` object.

* Fixed a SIGBUS crash with the OS X wheels caused by redefinition of a
  method.
* Fixed a runtime error ``undefined symbol EC_GFp_nistp224_method`` that
  occurred with some OpenSSL installations.

Log message:
Update py-cryptography to 1.1.1:

1.1.1 - 2015-11-19
~~~~~~~~~~~~~~~~~~

* Fixed several small bugs related to compiling the OpenSSL bindings with
  unusual OpenSSL configurations.
* Resolved an issue where, depending on the method of installation and
  which Python interpreter they were using, users on El Capitan (OS X 10.11)
  may have seen an ``InternalError`` on import.

Log message:
Update py-cryptography to 1.1:

1.1 - 2015-10-28
~~~~~~~~~~~~~~~~

* Added support for Elliptic Curve Diffie-Hellman with
  :class:`~cryptography.hazmat.primitives.asymmetric.ec.ECDH`.
* Added :class:`~cryptography.hazmat.primitives.kdf.x963kdf.X963KDF`.
* Added support for parsing certificate revocation lists (CRLs) using
  :func:`~cryptography.x509.load_pem_x509_crl` and
  :func:`~cryptography.x509.load_der_x509_crl`.
* Add support for AES key wrapping with
  :func:`~cryptography.hazmat.primitives.keywrap.aes_key_wrap` and
  :func:`~cryptography.hazmat.primitives.keywrap.aes_key_unwrap`.
* Added a ``__hash__`` method to :class:`~cryptography.x509.Name`.
* Add support for encoding and decoding elliptic curve points to a byte string
  form using
  \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers. \ 
encode_point`
  and
  \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers. \ 
from_encoded_point`.
* Added :meth:`~cryptography.x509.Extensions.get_extension_for_class`.
* :class:`~cryptography.x509.CertificatePolicies` are now supported in the
  :class:`~cryptography.x509.CertificateBuilder`.
* ``countryName`` is now encoded as a ``PrintableString`` when creating subject
  and issuer distinguished names with the Certificate and CSR builder classes.

Log message:
Update py-cryptography to 1.0.2:

1.0.2 - 2015-09-27
~~~~~~~~~~~~~~~~~~
* **SECURITY ISSUE**: The OpenSSL backend prior to 1.0.2 made extensive use
  of assertions to check response codes where our tests could not trigger a
  failure.  However, when Python is run with ``-O`` these asserts are optimized
  away.  If a user ran Python with this flag and got an invalid response code
  this could result in undefined behavior or worse. Accordingly, all response
  checks from the OpenSSL backend have been converted from ``assert``
  to a true function call. Credit **Emilia Käsper (Google Security Team)**
