[pyup-bot]

This PR updates cryptography from 2.7 to 2.9.2.

Changelog

2.9.1

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

* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1g.

.. _v2-9:

2.9

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

* **BACKWARDS INCOMPATIBLE:** Support for Python 3.4 has been removed due to
low usage and maintenance burden.
* **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.0.1 has been removed.
Users on older version of OpenSSL will need to upgrade.
* **BACKWARDS INCOMPATIBLE:** Support for LibreSSL 2.6.x has been removed.
* Removed support for calling
:meth:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey.public_bytes`
with no arguments, as per our deprecation policy. You must now pass
``encoding`` and ``format``.
* **BACKWARDS INCOMPATIBLE:** Reversed the order in which
:meth:`~cryptography.x509.Name.rfc4514_string` returns the RDNs
as required by :rfc:`4514`.
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1f.
* Added support for parsing
:attr:`~cryptography.x509.ocsp.OCSPResponse.single_extensions` in an OCSP
response.
* :class:`~cryptography.x509.NameAttribute` values can now be empty strings.

.. _v2-8:

2.8

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

* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
OpenSSL 1.1.1d.
* Added support for Python 3.8.
* Added class methods
:meth:`Poly1305.generate_tag
<cryptography.hazmat.primitives.poly1305.Poly1305.generate_tag>`
and
:meth:`Poly1305.verify_tag
<cryptography.hazmat.primitives.poly1305.Poly1305.verify_tag>`
for Poly1305 sign and verify operations.
* Deprecated support for OpenSSL 1.0.1. Support will be removed in
``cryptography`` 2.9.
* We now ship ``manylinux2010`` wheels in addition to our ``manylinux1``
wheels.
* Added support for ``ed25519`` and ``ed448`` keys in the
:class:`~cryptography.x509.CertificateBuilder`,
:class:`~cryptography.x509.CertificateSigningRequestBuilder`,
:class:`~cryptography.x509.CertificateRevocationListBuilder` and
:class:`~cryptography.x509.ocsp.OCSPResponseBuilder`.
* ``cryptography`` no longer depends on ``asn1crypto``.
* :class:`~cryptography.x509.FreshestCRL` is now allowed as a
:class:`~cryptography.x509.CertificateRevocationList` extension.
