* **SECURITY ISSUE:** Attempted to make RSA PKCS#1v1.5 decryption more constant
time, to protect against Bleichenbacher vulnerabilities. Due to limitations
imposed by our API, we cannot completely mitigate this vulnerability and a
future release will contain a new API which is designed to be resilient to
these for contexts where it is required. Credit to **Hubert Kario** for
reporting the issue. *CVE-2020-25659*
* Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL
will need to upgrade.
* Added basic support for PKCS7 signing (including SMIME) via
:class:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilder`.
.. _v3-1-1:
3.1.1 - 2020-09-22
Updated Windows, macOS, and manylinux wheels to be compiled with
OpenSSL 1.1.1h.
.. _v3-1:
3.1 - 2020-08-26
* **BACKWARDS INCOMPATIBLE:** Removed support for ``idna`` based
:term:`U-label` parsing in various X.509 classes. This support was originally
deprecated in version 2.1 and moved to an extra in 2.5.
* Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer supported by
the OpenSSL project. The next version of ``cryptography`` will drop support
for it.
* Deprecated support for Python 3.5. This version sees very little use and will
be removed in the next release.
* ``backend`` arguments to functions are no longer required and the
default backend will automatically be selected if no ``backend`` is provided.
* Added initial support for parsing certificates from PKCS7 files with
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates`
and
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates`
.
* Calling ``update`` or ``update_into`` on
:class:`~cryptography.hazmat.primitives.ciphers.CipherContext` with ``data``
longer than 2\ :sup:`31` bytes no longer raises an ``OverflowError``. This
also resolves the same issue in :doc:`/fernet`.
