Cryptography

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

* Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2g.


.. _v1-2-2:

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

* Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2f.


.. _v1-2-1:

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

* Reverts a change to an OpenSSL ``EVP_PKEY`` object that caused errors with
``pyOpenSSL``.


.. _v1-2:

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

* **BACKWARDS INCOMPATIBLE:**
:class:`~cryptography.x509.RevokedCertificate`
:attr:`~cryptography.x509.RevokedCertificate.extensions` now uses extension
classes rather than returning raw values inside the
:class:`~cryptography.x509.Extension`
:attr:`~cryptography.x509.Extension.value`. The new classes
are:

* :class:`~cryptography.x509.CertificateIssuer`
* :class:`~cryptography.x509.CRLReason`
* :class:`~cryptography.x509.InvalidityDate`
* Deprecated support for OpenSSL 0.9.8 and 1.0.0. At this time there is no time
table for actually dropping support, however we strongly encourage all users
to upgrade, as those versions no longer receive support from the OpenSSL
project.
* The :class:`~cryptography.x509.Certificate` class now has
:attr:`~cryptography.x509.Certificate.signature` and
:attr:`~cryptography.x509.Certificate.tbs_certificate_bytes` attributes.
* The :class:`~cryptography.x509.CertificateSigningRequest` class now has
:attr:`~cryptography.x509.CertificateSigningRequest.signature` and
:attr:`~cryptography.x509.CertificateSigningRequest.tbs_certrequest_bytes`
attributes.
* The :class:`~cryptography.x509.CertificateRevocationList` class now has
:attr:`~cryptography.x509.CertificateRevocationList.signature` and
:attr:`~cryptography.x509.CertificateRevocationList.tbs_certlist_bytes`
attributes.
* :class:`~cryptography.x509.NameConstraints` are now supported in the
:class:`~cryptography.x509.CertificateBuilder` and
:class:`~cryptography.x509.CertificateSigningRequestBuilder`.
* Support serialization of certificate revocation lists using the
:meth:`~cryptography.x509.CertificateRevocationList.public_bytes` method of
:class:`~cryptography.x509.CertificateRevocationList`.
* Add support for parsing :class:`~cryptography.x509.CertificateRevocationList`
:meth:`~cryptography.x509.CertificateRevocationList.extensions` in the
OpenSSL backend. The following extensions are currently supported:

* :class:`~cryptography.x509.AuthorityInformationAccess`
* :class:`~cryptography.x509.AuthorityKeyIdentifier`
* :class:`~cryptography.x509.CRLNumber`
* :class:`~cryptography.x509.IssuerAlternativeName`
* Added :class:`~cryptography.x509.CertificateRevocationListBuilder` and
:class:`~cryptography.x509.RevokedCertificateBuilder` to allow creation of
CRLs.
* Unrecognized non-critical X.509 extensions are now parsed into an
:class:`~cryptography.x509.UnrecognizedExtension` object.


.. _v1-1-2:

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

* Fixed a SIGBUS crash with the OS X wheels caused by redefinition of a
method.
* Fixed a runtime error ``undefined symbol EC_GFp_nistp224_method`` that
occurred with some OpenSSL installations.
* Updated Windows and OS X wheels to be compiled against OpenSSL 1.0.2e.


.. _v1-1-1:

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

* Fixed several small bugs related to compiling the OpenSSL bindings with
unusual OpenSSL configurations.
* Resolved an issue where, depending on the method of installation and
which Python interpreter they were using, users on El Capitan (OS X 10.11)
may have seen an ``InternalError`` on import.
