Bumps cryptography from 2.4.2 to 3.3.2.

Changelog

Sourced from cryptography's changelog.

3.3.2 - 2021-02-07

* **SECURITY ISSUE:** Fixed a bug where certain sequences of ``update()`` calls
  when symmetrically encrypting very large payloads (>2GB) could result in an
  integer overflow, leading to buffer overflows. *CVE-2020-36242* **Update:**
  This fix is a workaround for *CVE-2021-23840* in OpenSSL, fixed in OpenSSL
  1.1.1j.
.. _v3-3-1:
3.3.1 - 2020-12-09

• Re-added a legacy symbol causing problems for older pyOpenSSL users.

.. _v3-3:

3.3 - 2020-12-08

* **BACKWARDS INCOMPATIBLE:** Support for Python 3.5 has been removed due to
  low usage and maintenance burden.
* **BACKWARDS INCOMPATIBLE:** The
  :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` and
  :class:`~cryptography.hazmat.primitives.ciphers.aead.AESGCM` now require
  64-bit to 1024-bit (8 byte to 128 byte) initialization vectors. This change
  is to conform with an upcoming OpenSSL release that will no longer support
  sizes outside this window.
* **BACKWARDS INCOMPATIBLE:** When deserializing asymmetric keys we now
  raise ``ValueError`` rather than ``UnsupportedAlgorithm`` when an
  unsupported cipher is used. This change is to conform with an upcoming
  OpenSSL release that will no longer distinguish between error types.
* **BACKWARDS INCOMPATIBLE:** We no longer allow loading of finite field
  Diffie-Hellman parameters of less than 512 bits in length. This change is to
  conform with an upcoming OpenSSL release that no longer supports smaller
  sizes. These keys were already wildly insecure and should not have been used
  in any application outside of testing.
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
  OpenSSL 1.1.1i.
* Python 2 support is deprecated in ``cryptography``. This is the last release
  that will support Python 2.
* Added the
  :meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.recover_data_from_signature`
  function to
  :class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`
  for recovering the signed data from an RSA signature.
