* Fixed a bug where certain operations would fail if an object happened to be
in the top-half of the memory-space. This only impacted 32-bit systems.
.. _v40-0-0:
40.0.0 - 2023-03-24
BACKWARDS INCOMPATIBLE: As announced in the 39.0.0 changelog, the way
cryptography links OpenSSL has changed. This only impacts 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environment variables are no longer valid. Instead, users need to configure
their builds as documented here_.
Support for Python 3.6 is deprecated and will be removed in the next
release.
Deprecated the current minimum supported Rust version (MSRV) of 1.48.0.
In the next release we will raise MSRV to 1.56.0. 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 support for OpenSSL less than 1.1.1d. The next release of
cryptography will drop support for older versions.
Deprecated support for DSA keys in
:func:~cryptography.hazmat.primitives.serialization.load_ssh_public_key
and
:func:~cryptography.hazmat.primitives.serialization.load_ssh_private_key.
Deprecated support for OpenSSH serialization in
:class:~cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey
and
:class:~cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey.
The minimum supported version of PyPy3 is now 7.3.10.
Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.1.0.
Added support for parsing SSH certificates in addition to public keys with
:func:~cryptography.hazmat.primitives.serialization.load_ssh_public_identity.
:func:~cryptography.hazmat.primitives.serialization.load_ssh_public_key
continues to support only public keys.
Added support for generating SSH certificates with
:class:~cryptography.hazmat.primitives.serialization.SSHCertificateBuilder.
Added :meth:~cryptography.x509.Certificate.verify_directly_issued_by to
:class:~cryptography.x509.Certificate.
Added a check to :class:~cryptography.x509.NameConstraints to ensure that
:class:~cryptography.x509.DNSName constraints do not contain any *
wildcards.
Removed many unused CFFI OpenSSL bindings. This will not impact you unless
