<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 &lt;cryptography.x509.verification&gt;`
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
&lt;https://c2sp.org/chunked-encryption&gt;`_ 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.
&lt;/tr&gt;&lt;/table&gt;
