PyCA cryptography 1.4 released

[Paul Kehrer]

Courtesy of the PyCon sprints, PyCA cryptography 1.4 has been released to
PyPI. cryptography is a package which provides cryptographic recipes and
primitives to Python developers. Our goal is for it to be your
"cryptographic standard library". We support Python 2.6-2.7, Python 3.3+,
and PyPy.

Changelog:

* Support for OpenSSL 0.9.8 has been removed. Users on older versions of
OpenSSL will need to upgrade.
* Added KBKDFHMAC.
* Added support for OpenSSH public key serialization.
* Added support for SHA-2 in RSA OAEP when using OpenSSL 1.0.2 or greater.
* Added "one shot" sign() and verify() APIs to RSA keys.
