[pyup-bot]

This PR updates cryptography from 3.4.6 to 38.0.4.

Changelog

38.0.4

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

* Fixed compilation when using LibreSSL 3.6.0.
* Fixed error when using ``py2app`` to build an application with a
``cryptography`` dependency.

.. _v38-0-3:

38.0.3

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

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.7,
which resolves *CVE-2022-3602* and *CVE-2022-3786*.

.. _v38-0-2:

38.0.2

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

.. attention::

 This release was subsequently yanked from PyPI due to a regression in OpenSSL.

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.6.


.. _v38-0-1:

38.0.1

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

* Fixed parsing TLVs in ASN.1 with length greater than 65535 bytes (typically
seen in large CRLs).

.. _v38-0-0:

38.0.0

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

* 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
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.signature_hash_algorithm`,
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.signature_algorithm`,
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.signature`, and
:attr:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp.extension_bytes`.
* Added :attr:`~cryptography.x509.Certificate.tbs_precertificate_bytes`, allowing
users to access the to-be-signed pre-certificate data needed for signed
certificate timestamp verification.
* :class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFHMAC` and
:class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFCMAC` now support
:attr:`~cryptography.hazmat.primitives.kdf.kbkdf.CounterLocation.MiddleFixed`
counter location.
* Fixed :rfc:`4514` name parsing to reverse the order of the RDNs according
to the section 2.1 of the RFC, affecting method
:meth:`~cryptography.x509.Name.from_rfc4514_string`.
* It is now possible to customize some aspects of encryption when serializing
private keys, using
:meth:`~cryptography.hazmat.primitives.serialization.PrivateFormat.encryption_builder`.
* Removed several legacy symbols from our OpenSSL bindings. Users of pyOpenSSL
versions older than 22.0 will need to upgrade.
* Added
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES128` and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES256` classes.
These classes do not replace
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES` (which
allows all AES key lengths), but are intended for applications where
developers want to be explicit about key length.

.. _v37-0-4:

37.0.4

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

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.5.

.. _v37-0-3:

37.0.3

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

.. attention::

 This release was subsequently yanked from PyPI due to a regression in OpenSSL.

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.4.

.. _v37-0-2:

37.0.2

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

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.3.
* Added a constant needed for an upcoming pyOpenSSL release.

.. _v37-0-1:

37.0.1

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

* 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``.

.. _v37-0-0:

37.0.0

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

* 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.
In the next release we will raise MSRV to 1.48.0. 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.
* Deprecated
: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` because
they are legacy algorithms with extremely low usage. These will be removed
in a future version of ``cryptography``.
* Added limited support for distinguished names containing a bit string.
* We now ship ``universal2`` wheels on macOS, which contain both ``arm64``
and ``x86_64`` architectures. Users on macOS should upgrade to the latest
``pip`` to ensure they can use this wheel, although we will continue to
ship ``x86_64`` specific wheels for now to ease the transition.
* This will be the final release for which we ship ``manylinux2010`` wheels.
Going forward the minimum supported ``manylinux`` ABI for our wheels will
be ``manylinux2014``. The vast majority of users will continue to receive
``manylinux`` wheels provided they have an up to date ``pip``. For PyPy
wheels this release already requires ``manylinux2014`` for compatibility
with binaries distributed by upstream.
* Added support for multiple
:class:`~cryptography.x509.ocsp.OCSPSingleResponse` in a
:class:`~cryptography.x509.ocsp.OCSPResponse`.
* Restored support for signing certificates and other structures in
:doc:`/x509/index` with SHA3 hash algorithms.
* :class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES` is
disabled in FIPS mode.
* Added support for serialization of PKCS12 CA friendly names/aliases in
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.serialize_key_and_certificates`
* Added support for 12-15 byte (96 to 120 bit) nonces to
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESOCB3`. This class
previously supported only 12 byte (96 bit).
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESSIV` when using
OpenSSL 3.0.0+.
* Added support for serializing PKCS7 structures from a list of
certificates with
:class:`~cryptography.hazmat.primitives.serialization.pkcs7.serialize_certificates`.
* Added support for parsing :rfc:`4514` strings with
:meth:`~cryptography.x509.Name.from_rfc4514_string`.
* Added :attr:`~cryptography.hazmat.primitives.asymmetric.padding.PSS.AUTO` to
:class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS`. This can
be used to verify a signature where the salt length is not already known.
* Added :attr:`~cryptography.hazmat.primitives.asymmetric.padding.PSS.DIGEST_LENGTH`
to :class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS`. This
constant will set the salt length to the same length as the ``PSS`` hash
algorithm.
* Added support for loading RSA-PSS key types with
:func:`~cryptography.hazmat.primitives.serialization.load_pem_private_key`
and
:func:`~cryptography.hazmat.primitives.serialization.load_der_private_key`.
This functionality is limited to OpenSSL 1.1.1e+ and loads the key as a
normal RSA private key, discarding the PSS constraint information.

.. _v36-0-2:

36.0.2

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

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 1.1.1n.

.. _v36-0-1:

36.0.1

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

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 1.1.1m.

.. _v36-0-0:

36.0.0

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

* **FINAL DEPRECATION** Support for ``verifier`` and ``signer`` on our
asymmetric key classes was deprecated in version 2.0. 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 :doc:`/x509/index` 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:
:class:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey`).
* :ref:`Deprecated the backend argument<faq-missing-backend>` for all
functions.
* Added support for
:class:`~cryptography.hazmat.primitives.ciphers.aead.AESOCB3`.
* Added support for iterating over arbitrary request
:attr:`~cryptography.x509.CertificateSigningRequest.attributes`.
* Deprecated the ``get_attribute_for_oid`` method on
:class:`~cryptography.x509.CertificateSigningRequest` in favor of
:meth:`~cryptography.x509.Attributes.get_attribute_for_oid` on the new
:class:`~cryptography.x509.Attributes` object.
* Fixed handling of PEM files to allow loading when certificate and key are
in the same file.
* Fixed parsing of :class:`~cryptography.x509.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
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.load_pkcs12`,
which will return an object of type
:class:`~cryptography.hazmat.primitives.serialization.pkcs12.PKCS12KeyAndCertificates`.
* :meth:`~cryptography.x509.Name.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
:meth:`~cryptography.x509.Name.rfc4514_string` methods from version 35.0.

The previous behavior can be restored with:
``name.rfc4514_string({NameOID.EMAIL_ADDRESS: "E"})``
* Allow
:class:`~cryptography.hazmat.primitives.asymmetric.x25519.X25519PublicKey`
and
:class:`~cryptography.hazmat.primitives.asymmetric.x448.X448PublicKey` to
be used as public keys when parsing certificates or creating them with
:class:`~cryptography.x509.CertificateBuilder`. These key types must be
signed with a different signing algorithm as ``X25519`` and ``X448`` do
not support signing.
* Extension values can now be serialized to a DER byte string by calling
:func:`~cryptography.x509.ExtensionType.public_bytes`.
* Added experimental support for compiling against BoringSSL. As BoringSSL
does not commit to a stable API, ``cryptography`` tests against the
latest commit only. Please note that several features are not available
when building against BoringSSL.
* Parsing ``CertificateSigningRequest`` from DER and PEM now, for a limited
time period, allows the ``Extension`` ``critical`` field to be incorrectly
encoded. See `the issue <https://github.com/pyca/cryptography/issues/6368>`_
for complete details. This will be reverted in a future ``cryptography``
release.
* When :class:`~cryptography.x509.OCSPNonce` are parsed and generated their
value is now correctly wrapped in an ASN.1 ``OCTET STRING``. This conforms
to :rfc:`6960` but conflicts with the original behavior specified in
:rfc:`2560`. For a temporary period for backwards compatibility, we will
also parse values that are encoded as specified in :rfc:`2560` but this
behavior will be removed in a future release.

.. _v35-0-0:

35.0.0

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

* Changed the :ref:`version scheme <api-stability:versioning>`. This will
result in us incrementing the major version more frequently, but does not
change our existing backwards compatibility policy.
* **BACKWARDS INCOMPATIBLE:** The :doc:`/x509/index` PEM parsers now require
that the PEM string passed have PEM delimiters of the correct type. For
example, parsing a private key PEM concatenated with a certificate PEM will
no longer be accepted by the PEM certificate parser.
* **BACKWARDS INCOMPATIBLE:** The X.509 certificate parser no longer allows
negative serial numbers. :rfc:`5280` has always prohibited these.
* **BACKWARDS INCOMPATIBLE:** Additional forms of invalid ASN.1 found during
:doc:`/x509/index` parsing will raise an error on initial parse rather than
when the malformed field is accessed.
* Rust is now required for building ``cryptography``, the
``CRYPTOGRAPHY_DONT_BUILD_RUST`` environment variable is no longer
respected.
* Parsers for :doc:`/x509/index` no longer use OpenSSL and have been
rewritten in Rust. This should be backwards compatible (modulo the items
listed above) and improve both security and performance.
* Added support for OpenSSL 3.0.0 as a compilation target.
* Added support for
:class:`~cryptography.hazmat.primitives.hashes.SM3` and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.SM4`,
when using OpenSSL 1.1.1. These algorithms are provided for compatibility
in regions where they may be required, and are not generally recommended.
* We now ship ``manylinux_2_24`` and ``musllinux_1_1`` wheels, in addition to
our ``manylinux2010`` and ``manylinux2014`` wheels. Users on distributions
like Alpine Linux should ensure they upgrade to the latest ``pip`` to
correctly receive wheels.
* Added ``rfc4514_attribute_name`` attribute to :attr:`x509.NameAttribute
<cryptography.x509.NameAttribute.rfc4514_attribute_name>`.
* Added :class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFCMAC`.
