Cryptography

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

* Deprecated ``salt_length`` on
:class:`~cryptography.hazmat.primitives.asymmetric.padding.MGF1` and added it
to :class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS`. It will
be removed from ``MGF1`` in two releases per our :doc:`/api-stability`
policy.
* Added :class:`~cryptography.hazmat.primitives.ciphers.algorithms.SEED`
support.
* Added :class:`~cryptography.hazmat.primitives.cmac.CMAC`.
* Added decryption support to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey`
and encryption support to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`.
* Added signature support to
:class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey`
and verification support to
:class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey`.


.. _v0-3:

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

* Added :class:`~cryptography.hazmat.primitives.twofactor.hotp.HOTP`.
* Added :class:`~cryptography.hazmat.primitives.twofactor.totp.TOTP`.
* Added :class:`~cryptography.hazmat.primitives.ciphers.algorithms.IDEA`
support.
* Added signature support to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey`
and verification support to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`.
* Moved test vectors to the new ``cryptography_vectors`` package.


.. _v0-2-2:

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

* Removed a constant definition that was causing compilation problems with
specific versions of OpenSSL.


.. _v0-2-1:

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

* Fix a bug where importing cryptography from multiple paths could cause
initialization to fail.


.. _v0-2:

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

* Added ``commoncrypto``.
* Added initial ``commoncrypto``.
* Removed ``register_cipher_adapter`` method from ``CipherBackend``.
* Added support for the OpenSSL backend under Windows.
* Improved thread-safety for the OpenSSL backend.
* Fixed compilation on systems where OpenSSL's ``ec.h`` header is not
available, such as CentOS.
* Added :class:`~cryptography.hazmat.primitives.kdf.pbkdf2.PBKDF2HMAC`.
* Added :class:`~cryptography.hazmat.primitives.kdf.hkdf.HKDF`.
* Added ``multibackend``.
* Set default random for ``openssl`` to the OS random engine.
* Added :class:`~cryptography.hazmat.primitives.ciphers.algorithms.CAST5`
(CAST-128) support.


.. _v0-1:

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

* Initial release.
