Bumps [cryptography](https://github.com/pyca/cryptography) from 49.0.0 to 50.0.0. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/pyca/cryptography/blob/main/CHANGELOG.rst";>cryptography's changelog</a>.</em></p> <blockquote> <p>50.0.0 - 2026-07-31</p> <pre><code> * **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. </tr></table> </code></pre> </blockquote> <p>...
