Updates cryptography to 50.0.0

Changelog

Sourced from cryptography's changelog.

50.0.0 - 2026-07-31

* **SECURITY ISSUE**:
  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der`
  and its PEM and S/MIME variants no longer expose distinguishable errors or
  timing when unwrapping a ``RecipientInfo``'s ``encryptedKey``, which could
  act as a Bleichenbacher oracle for callers that decrypt untrusted messages.
  A random key is now substituted on failure, as described in :rfc:`3218`.
  Credit to **@X1AOxiang** for reporting the issue. **CVE-2026-69247**
* Deprecated Diffie-Hellman key exchange over finite fields (FFDH).
  Everything FFDH is deprecated, including the types in
  ``cryptography.hazmat.primitives.asymmetric.dh`` and loading FFDH keys or
  parameters with the key loading APIs. Users should migrate to a more
  modern key exchange algorithm.
* Added ``xof()`` class methods to
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE128` and
  :class:`~cryptography.hazmat.primitives.hashes.SHAKE256` for constructing
  algorithm instances configured for use with
  :class:`~cryptography.hazmat.primitives.hashes.XOFHash`.
* The :mod:`X.509 verification <cryptography.x509.verification>` APIs are now
  considered stable and are subject to our API stability policy.
* Added the :doc:`/cobblestone` recipe, an implementation of the
  Cobblestone-128 and Cobblestone-256 instantiations of the `C2SP
  chunked-encryption specification
  <https://c2sp.org/chunked-encryption>`_ for streaming authenticated
  encryption of large messages.
* Parsing a Signed Certificate Timestamp list now rejects encodings that
  carry trailing bytes after the list or after an individual SCT, instead of
  silently ignoring them.
* Added support for using :class:`~cryptography.x509.Name` as a field type in
  the :doc:`/hazmat/asn1/index` module.
* Loading a public key or an EC private key now rejects DER where the
  ``subjectPublicKey`` (or EC ``publicKey``) ``BIT STRING`` declares a non-zero
  number of unused bits, instead of silently ignoring it.
* Parsing a CRL entry's ``InvalidityDate`` extension now rejects a
  ``GeneralizedTime`` that carries fractional seconds or another non-DER form,
  matching the strict encoding already required for every other X.509 time
  field.
* :func:`~cryptography.x509.ocsp.load_der_ocsp_request` and
  :func:`~cryptography.x509.ocsp.load_der_ocsp_response` now reject a request
  or response whose ``version`` field is not ``v1``, the only version defined
  by RFC 6960, matching the version validation already performed when loading
  certificates, CSRs and CRLs.
* :class:`~cryptography.hazmat.primitives.hashes.XOFHash` is now supported
  when building against AWS-LC.
* HMAC (and therefore PBKDF2-HMAC) with SHA-3 hashes is now supported when
  building against AWS-LC.
* Diffie-Hellman (:doc:`/hazmat/primitives/asymmetric/dh`) is now supported
  when building against AWS-LC.

Updates requests to 2.34.2

Release notes

Sourced from requests's releases.

v2.34.2

2.34.2 (2026-05-14)

• Moved headers input type back to Mapping to avoid invariance issues with MutableMapping and inferred dict types. Users calling Request.headers.update() may need to narrow typing in their code. (#7441)

2.34.2 (2026-05-14)

• Moved headers input type back to Mapping to avoid invariance issues with MutableMapping and inferred dict types. Users calling Request.headers.update() may need to narrow typing in their code. (#7441)

2.34.1 (2026-05-13)

Bugfixes

• Widened json input type from dict and list to Mapping and Sequence. (#7436)
• Changed headers input type to MutableMapping and removed None from Request.headers typing to improve handling for users. (#7431)
• Response.reason moved from str | None to str to improve handling for users. (#7437)
• Fixed a bug where some bodies with custom __getattr__ implementations weren't being properly detected as Iterables. (#7433)

2.34.0 (2026-05-11)

Announcements

• Requests 2.34.0 introduces inline types, replacing those provided by typeshed. Public API types should be fully compatible with mypy, pyright, and ty. We believe types are comprehensive but if you find issues, please report them to the pinned tracking issue.

  Special thanks to @​bastimeyer, @​cthoyt, @​edgarrmondragon, and @​srittau for helping review and test the types ahead of the release. (#7272)

Improvements

• Digest Auth hashing algorithms have added usedforsecurity=False to clarify security considerations. (#7310)
• Requests added support for Python 3.15 based on beta1. Downstream projects should be able to start testing prior to its release in October. (#7422)
• Requests added support for Python 3.14t. (#7419)

Bugfixes

• Response.history no longer contains a reference to itself, preventing accidental looping when traversing the history list. (#7328)
• Requests no longer performs greedy matching on no_proxy domains. The proxy_bypass implementation has been updated with CPython's fix from bpo-39057. (#7427)
• Requests no longer incorrectly strips duplicate leading slashes in URI paths. This should address user issues with specific presigned URLs. Note the full fix requires urllib3 2.7.0+. (#7315)
