dependabot(deps): update cryptography requirement from <=3.2.1,>2.9.2 to >2.9.2,<3.4.0

[dependabot]

Updates the requirements on cryptography to permit the latest version.

Changelog

Sourced from cryptography's changelog.

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.
.. _v3-2-1:
3.2.1 - 2020-10-27

• Disable blinding on RSA public keys to address an error with some versions of OpenSSL.

.. _v3-2:

3.2 - 2020-10-25

* **SECURITY ISSUE:** Attempted to make RSA PKCS#1v1.5 decryption more constant
  time, to protect against Bleichenbacher vulnerabilities. Due to limitations
  imposed by our API, we cannot completely mitigate this vulnerability and a
  future release will contain a new API which is designed to be resilient to
  these for contexts where it is required. Credit to **Hubert Kario** for
  reporting the issue. *CVE-2020-25659*
* Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL
</tr></table>
