Changelog

43.0.1

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.3.2.

.. _v43-0-0:

43.0.0

~~~~~~~~~~~~~~~~~~~

* **BACKWARDS INCOMPATIBLE:** Support for OpenSSL less than 1.1.1e has been
removed.  Users on older version of OpenSSL will need to upgrade.
* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 3.8.
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.3.1.
* Updated the minimum supported Rust version (MSRV) to 1.65.0, from 1.63.0.
* :func:`~cryptography.hazmat.primitives.asymmetric.rsa.generate_private_key`
now enforces a minimum RSA key size of 1024-bit. Note that 1024-bit is still
considered insecure, users should generally use a key size of 2048-bits.
* :func:`~cryptography.hazmat.primitives.serialization.pkcs7.serialize_certificates`
now emits ASN.1 that more closely follows the recommendations in :rfc:`2315`.
* Added new :doc:`/hazmat/decrepit/index` module which contains outdated and
insecure cryptographic primitives.
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.CAST5`,
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.SEED`,
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.IDEA`, and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.Blowfish`, which were
deprecated in 37.0.0, have been added to this module. They will be removed
from the ``cipher`` module in 45.0.0.
* Moved :class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES`
and :class:`~cryptography.hazmat.primitives.ciphers.algorithms.ARC4` into
:doc:`/hazmat/decrepit/index` and deprecated them in the ``cipher`` module.
They will be removed from the ``cipher`` module in 48.0.0.
* Added support for deterministic
:class:`~cryptography.hazmat.primitives.asymmetric.ec.ECDSA` (:rfc:`6979`)
* Added support for client certificate verification to the
:mod:`X.509 path validation <cryptography.x509.verification>` APIs in the
form of :class:`~cryptography.x509.verification.ClientVerifier`,
:class:`~cryptography.x509.verification.VerifiedClient`, and
``PolicyBuilder``
:meth:`~cryptography.x509.verification.PolicyBuilder.build_client_verifier`.
* Added Certificate
:attr:`~cryptography.x509.Certificate.public_key_algorithm_oid`
and Certificate Signing Request
:attr:`~cryptography.x509.CertificateSigningRequest.public_key_algorithm_oid`
to determine the :class:`~cryptography.hazmat._oid.PublicKeyAlgorithmOID`
Object Identifier of the public key found inside the certificate.
* Added :attr:`~cryptography.x509.InvalidityDate.invalidity_date_utc`, a
timezone-aware alternative to the naïve ``datetime`` attribute
:attr:`~cryptography.x509.InvalidityDate.invalidity_date`.
* Added support for parsing empty DN string in
:meth:`~cryptography.x509.Name.from_rfc4514_string`.
* Added the following properties that return timezone-aware ``datetime`` objects:
:meth:`~cryptography.x509.ocsp.OCSPResponse.produced_at_utc`,
:meth:`~cryptography.x509.ocsp.OCSPResponse.revocation_time_utc`,
:meth:`~cryptography.x509.ocsp.OCSPResponse.this_update_utc`,
:meth:`~cryptography.x509.ocsp.OCSPResponse.next_update_utc`,
:meth:`~cryptography.x509.ocsp.OCSPSingleResponse.revocation_time_utc`,
:meth:`~cryptography.x509.ocsp.OCSPSingleResponse.this_update_utc`,
:meth:`~cryptography.x509.ocsp.OCSPSingleResponse.next_update_utc`,
These are timezone-aware variants of existing properties that return naïve
``datetime`` objects.
* Added
:func:`~cryptography.hazmat.primitives.asymmetric.rsa.rsa_recover_private_exponent`
* Added :meth:`~cryptography.hazmat.primitives.ciphers.CipherContext.reset_nonce`
for altering the ``nonce`` of a cipher context without initializing a new
instance. See the docs for additional restrictions.
* :class:`~cryptography.x509.NameAttribute` now raises an exception when
attempting to create a common name whose length is shorter or longer than
:rfc:`5280` permits.
* Added basic support for PKCS7 encryption (including SMIME) via
:class:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7EnvelopeBuilder`.

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.2.2.

.. _v42-0-7:

42.0.7

~~~~~~~~~~~~~~~~~~~

* Restored Windows 7 compatibility for our pre-built wheels. Note that we do
not test on Windows 7 and wheels for our next release will not support it.
Microsoft no longer provides support for Windows 7 and users are encouraged
to upgrade.

.. _v42-0-6:

42.0.6

~~~~~~~~~~~~~~~~~~~

* Fixed compilation when using LibreSSL 3.9.1.

.. _v42-0-5:

42.0.5

~~~~~~~~~~~~~~~~~~~

* Limit the number of name constraint checks that will be performed in
:mod:`X.509 path validation <cryptography.x509.verification>` to protect
against denial of service attacks.
* Upgrade ``pyo3`` version, which fixes building on PowerPC.

.. _v42-0-4:

42.0.4

~~~~~~~~~~~~~~~~~~~

* Fixed a null-pointer-dereference and segfault that could occur when creating
a PKCS12 bundle. Credit to **Alexander-Programming** for reporting the
issue. **CVE-2024-26130**
* Fixed ASN.1 encoding for PKCS7/SMIME signed messages. The fields ``SMIMECapabilities``
and ``SignatureAlgorithmIdentifier`` should now be correctly encoded according to the
definitions in :rfc:`2633` :rfc:`3370`.

.. _v42-0-3:

42.0.3

~~~~~~~~~~~~~~~~~~~

* Fixed an initialization issue that caused key loading failures for some
users.

.. _v42-0-2:

42.0.2

~~~~~~~~~~~~~~~~~~~

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.2.1.
* Fixed an issue that prevented the use of Python buffer protocol objects in
``sign`` and ``verify`` methods on asymmetric keys.

.. _v42-0-0:

42.0.0

~~~~~~~~~~~~~~~~~~~

* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 3.7.
* **BACKWARDS INCOMPATIBLE:** Loading a PKCS7 with no content field using
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates`
or
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates`
will now raise a ``ValueError`` rather than return an empty list.
* Parsing SSH certificates no longer permits malformed critical options with
values, as documented in the 41.0.2 release notes.
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.2.0.
* Updated the minimum supported Rust version (MSRV) to 1.63.0, from 1.56.0.
* We now publish both ``py37`` and ``py39`` ``abi3`` wheels. This should
resolve some errors relating to initializing a module multiple times per
process.
* Support :class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS` for
X.509 certificate signing requests and certificate revocation lists with the
keyword-only argument ``rsa_padding`` on the ``sign`` methods for
:class:`~cryptography.x509.CertificateSigningRequestBuilder` and
:class:`~cryptography.x509.CertificateRevocationListBuilder`.
* Added support for obtaining X.509 certificate signing request signature
algorithm parameters (including PSS) via
:meth:`~cryptography.x509.CertificateSigningRequest.signature_algorithm_parameters`.
* Added support for obtaining X.509 certificate revocation list signature
algorithm parameters (including PSS) via
:meth:`~cryptography.x509.CertificateRevocationList.signature_algorithm_parameters`.
* Added ``mgf`` property to
:class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS`.
* Added ``algorithm`` and ``mgf`` properties to
:class:`~cryptography.hazmat.primitives.asymmetric.padding.OAEP`.

:meth:`~cryptography.x509.Certificate.not_valid_after_utc`,
:meth:`~cryptography.x509.RevokedCertificate.revocation_date_utc`,
:meth:`~cryptography.x509.CertificateRevocationList.next_update_utc`,
:meth:`~cryptography.x509.CertificateRevocationList.last_update_utc`.
These are timezone-aware variants of existing properties that return naïve
``datetime`` objects.
* Deprecated the following properties that return naïve ``datetime`` objects:
:meth:`~cryptography.x509.Certificate.not_valid_before`,
:meth:`~cryptography.x509.Certificate.not_valid_after`,
:meth:`~cryptography.x509.RevokedCertificate.revocation_date`,
:meth:`~cryptography.x509.CertificateRevocationList.next_update`,
:meth:`~cryptography.x509.CertificateRevocationList.last_update`
in favor of the new timezone-aware variants mentioned above.
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.ChaCha20`
on LibreSSL.
* Added support for RSA PSS signatures in PKCS7 with
:meth:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder.add_signer`.
* In the next release (43.0.0) of cryptography, loading an X.509 certificate
with a negative serial number will raise an exception. This has been
deprecated since 36.0.0.
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESGCMSIV` when using
OpenSSL 3.2.0+.
* Added the :mod:`X.509 path validation <cryptography.x509.verification>` APIs
for :class:`~cryptography.x509.Certificate` chains. These APIs should be
considered unstable and not subject to our stability guarantees until
documented as such in a future release.
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.SM4`
:class:`~cryptography.hazmat.primitives.ciphers.modes.GCM`
when using OpenSSL 3.0 or greater.

.. _v41-0-7:
