Changelog

Sourced from cryptography's changelog.

48.0.0 - 2026-05-04

* **BACKWARDS INCOMPATIBLE:** Support for Python 3.8 has been removed.
  ``cryptography`` now requires Python 3.9 or later.
* **BACKWARDS INCOMPATIBLE:** Loading an X.509 CRL whose inner
  ``TBSCertList.signature`` algorithm does not match the outer
  ``signatureAlgorithm`` now raises ``ValueError``. Previously, such CRLs
  were parsed successfully and only rejected during signature validation.
* Added support for :doc:`/hazmat/primitives/asymmetric/mlkem` and
  :doc:`/hazmat/primitives/asymmetric/mldsa` when using OpenSSL 3.5.0 or
  later, in addition to the existing AWS-LC and BoringSSL support. This means
  post-quantum algorithms are now available to users of our wheels.

Note: Going forward, we do not guarantee that all functionality

in cryptography will be available when building against

OpenSSL. See :doc:/statements/state-of-openssl for more information.

.. _v47-0-0:
47.0.0 - 2026-04-24

• Support for Python 3.8 is deprecated and will be removed in the next cryptography release.
• BACKWARDS INCOMPATIBLE: Support for binary elliptic curves (SECT* classes) has been removed. These curves are rarely used and have additional security considerations that make them undesirable.
• BACKWARDS INCOMPATIBLE: Support for OpenSSL 1.1.x has been removed. OpenSSL 3.0.0 or later is now required. LibreSSL, BoringSSL, and AWS-LC continue to be supported.
• BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL < 4.1.
• BACKWARDS INCOMPATIBLE: Loading keys with unsupported algorithms or keys with unsupported explicit curve encodings now raises :class:~cryptography.exceptions.UnsupportedAlgorithm instead of ValueError. This change affects :func:~cryptography.hazmat.primitives.serialization.load_pem_private_key, :func:~cryptography.hazmat.primitives.serialization.load_der_private_key, :func:~cryptography.hazmat.primitives.serialization.load_pem_public_key, :func:~cryptography.hazmat.primitives.serialization.load_der_public_key, and :meth:~cryptography.x509.Certificate.public_key when called on certificates with unsupported public key algorithms.
• BACKWARDS INCOMPATIBLE: When parsing elliptic curve private keys, we now reject keys that incorrectly encode a private key of the wrong length because such keys are impossible to process in a constant-time manner. We do not believe keys with this problem are in wide use, however we may revert this change based on the feedback we receive.
• Deprecated passing 64-bit (8-byte) and 128-bit (16-byte) keys to :class:~cryptography.hazmat.decrepit.ciphers.algorithms.TripleDES. In a
