- update to 39.0.0:
* **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.1.0 has been removed.
Users on older version of OpenSSL will need to upgrade.
* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 3.5. The new
minimum LibreSSL version is 3.5.0. Going forward our policy is to support
versions of LibreSSL that are available in versions of OpenBSD that are
still receiving security support.
* **BACKWARDS INCOMPATIBLE:** Removed the ``encode_point`` and
``from_encoded_point`` methods on
:class:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers`,
which had been deprecated for several years.
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.public_bytes`
and
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.from_encoded_point`
should be used instead.
* **BACKWARDS INCOMPATIBLE:** Support for using MD5 or SHA1 in
:class:`~cryptography.x509.CertificateBuilder`, other X.509 builders, and
PKCS7 has been removed.
* **ANNOUNCEMENT:** The next version of ``cryptography`` (40.0) will
change
the way we link OpenSSL. This will only impact users who build
``cryptography`` from source (i.e., not from a ``wheel``), and specify their
own version of OpenSSL. For those users, the ``CFLAGS``, ``LDFLAGS``,
``INCLUDE``, ``LIB``, and ``CRYPTOGRAPHY_SUPPRESS_LINK_FLAGS`` environment
variables will no longer be respected. Instead, users will need to
configure their builds `as documented here`_.
* Added support for disabling the legacy provider in OpenSSL 3.0.x
* Added support for disabling RSA key validation checks when loading RSA
keys via
~cryptography.hazmat.primitives.serialization.load_pem_private_key

- update to 38.0.1:
* Fixed parsing TLVs in ASN.1 with length greater than 65535 bytes (typically
seen in large CRLs).
* Final deprecation of OpenSSL 1.1.0. The next release of ``cryptography``
will drop support.
* We no longer ship ``manylinux2010`` wheels. Users should upgrade to the
latest ``pip`` to ensure this doesn't cause issues downloading wheels on
their platform. We now ship ``manylinux_2_28`` wheels for users on new
enough platforms.
* Updated the minimum supported Rust version (MSRV) to 1.48.0, from 1.41.0.
Users with the latest ``pip`` will typically get a wheel and not need Rust
installed, but check :doc:`/installation` for documentation on installing a
newer ``rustc`` if required.
* :meth:`~cryptography.fernet.Fernet.decrypt` and related methods now accept
both ``str`` and ``bytes`` tokens.
* Parsing ``CertificateSigningRequest`` restores the behavior of enforcing
that the ``Extension`` ``critical`` field must be correctly encoded DER. See
`the issue <https://github.com/pyca/cryptography/issues/6368>`_ for complete
details.
* Added two new OpenSSL functions to the bindings to support an upcoming
``pyOpenSSL`` release.
* When parsing :class:`~cryptography.x509.CertificateRevocationList` and
:class:`~cryptography.x509.CertificateSigningRequest` values, it is now
enforced that the ``version`` value in the input must be valid according to
the rules of :rfc:`2986` and :rfc:`5280`.
* Using MD5 or SHA1 in :class:`~cryptography.x509.CertificateBuilder` and
other X.509 builders is deprecated and support will be removed in the next
version.
* Added additional APIs to
:class:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp`, including

- update to 37.0.2:
* Fixed an issue where parsing an encrypted private key with the public
loader functions would hang waiting for console input on OpenSSL 3.0.x rather
than raising an error.
* Restored some legacy symbols for older ``pyOpenSSL`` users. These will be
removed again in the future, so ``pyOpenSSL`` users should still upgrade
to the latest version of that package when they upgrade ``cryptography``.
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.2.
* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL 2.9.x and 3.0.x.
The new minimum LibreSSL version is 3.1+.
* **BACKWARDS INCOMPATIBLE:** Removed ``signer`` and ``verifier`` methods
from the public key and private key classes. These methods were originally
deprecated in version 2.0, but had an extended deprecation timeline due
to usage. Any remaining users should transition to ``sign`` and ``verify``.
* Deprecated OpenSSL 1.1.0 support. OpenSSL 1.1.0 is no longer supported by
the OpenSSL project. The next release of ``cryptography`` will be the last
to support compiling with OpenSSL 1.1.0.
* Deprecated Python 3.6 support. Python 3.6 is no longer supported by the
Python core team. Support for Python 3.6 will be removed in a future
``cryptography`` release.
* Deprecated the current minimum supported Rust version (MSRV) of 1.41.0.

``pip`` will typically get a wheel and not need Rust installed, but check
:doc:`/installation` for documentation on installing a newer ``rustc`` if

- update to 36.0.0:
* FINAL DEPRECATION Support for verifier and signer on our asymmetric key
classes was deprecated in version 2.1. These functions had an extended
deprecation due to usage, however the next version of cryptography will
drop support. Users should migrate to sign and verify.
* The entire X.509 layer is now written in Rust. This allows alternate
asymmetric key implementations that can support cloud key management
services or hardware security modules provided they implement the necessary
interface (for example: EllipticCurvePrivateKey).
* Deprecated the backend argument for all functions.
* Added support for AESOCB3.
* Added support for iterating over arbitrary request attributes.
* Deprecated the get_attribute_for_oid method on CertificateSigningRequest in
favor of get_attribute_for_oid() on the new Attributes object.
* Fixed handling of PEM files to allow loading when certificate and key are
in the same file.
* Fixed parsing of CertificatePolicies extensions containing legacy BMPString values in their explicitText.
* Allow parsing of negative serial numbers in certificates. Negative serial
numbers are prohibited by RFC 5280 so a deprecation warning will be raised
whenever they are encountered. A future version of cryptography will drop
support for parsing them.
* Added support for parsing PKCS12 files with friendly names for all
certificates with load_pkcs12(), which will return an object of type
PKCS12KeyAndCertificates.
* rfc4514_string() and related methods now have an optional
attr_name_overrides parameter to supply custom OID to name mappings, which
can be used to match vendor-specific extensions.
* BACKWARDS INCOMPATIBLE: Reverted the nonstandard formatting of email
address fields as E in rfc4514_string() methods from version 35.0.
* The previous behavior can be restored with:

- update to 3.3.0
- BACKWARDS INCOMPATIBLE: Support for Python 3.5 has been removed
due to low usage and maintenance burden.
- BACKWARDS INCOMPATIBLE: The GCM and AESGCM now require 64-bit
to 1024-bit (8 byte to 128 byte) initialization vectors. This
change is to conform with an upcoming OpenSSL release that will
no longer support sizes outside this window.
- BACKWARDS INCOMPATIBLE: When deserializing asymmetric keys we
now raise ValueError rather than UnsupportedAlgorithm when an
unsupported cipher is used. This change is to conform with an
upcoming OpenSSL release that will no longer distinguish
between error types.
- BACKWARDS INCOMPATIBLE: We no longer allow loading of finite
field Diffie-Hellman parameters of less than 512 bits in
length. This change is to conform with an upcoming OpenSSL
release that no longer supports smaller sizes. These keys were
already wildly insecure and should not have been used in any
application outside of testing.
- Updated Windows, macOS, and manylinux wheels to be compiled
with OpenSSL 1.1.1i.
- Python 2 support is deprecated in cryptography. This is the
last release that will support Python 2.
- Added the recover_data_from_signature() function to
RSAPublicKey for recovering the signed data from an RSA
signature.
- Remove unnecessary dependency virtualenv.

* **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`.
