Changelog ========= 0.7 - `master`_ ~~~~~~~~~~~~~~~ .. note:: This version is not yet released and is under active development. * Cryptography has been relicensed from the Apache Software License, Version 2.0, to being available under *either* the Apache Software License, Version 2.0, or the BSD license. * Added key-rotation support to :doc:`Fernet ` with :class:`~cryptography.fernet.MultiFernet`. * More bit-lengths are now support for ``p`` and ``q`` when loading DSA keys from numbers. * Added :class:`~cryptography.hazmat.primitives.interfaces.MACContext` as a common interface for CMAC and HMAC and deprecated :class:`~cryptography.hazmat.primitives.interfaces.CMACContext`. * Added support for encoding and decoding :rfc:`6979` signatures in :doc:`/hazmat/primitives/asymmetric/utils`. * Added :func:`~cryptography.hazmat.primitives.serialization.load_ssh_public_key` to support the loading of OpenSSH public keys (:rfc:`4253`). Currently, only RSA keys are supported. 0.6.1 - 2014-10-15 ~~~~~~~~~~~~~~~~~~ * Updated Windows wheels to be compiled against OpenSSL 1.0.1j. * Fixed an issue where OpenSSL 1.0.1j changed the errors returned by some functions. * Added our license file to the ``cryptography-vectors`` package. * Implemented DSA hash truncation support (per FIPS 186-3) in the OpenSSL backend. This works around an issue in 1.0.0, 1.0.0a, and 1.0.0b where truncation was not implemented. 0.6 - 2014-09-29 ~~~~~~~~~~~~~~~~ * Added :func:`~cryptography.hazmat.primitives.serialization.load_pem_private_key` to ease loading private keys, and :func:`~cryptography.hazmat.primitives.serialization.load_pem_public_key` to support loading public keys. * Removed the, deprecated in 0.4, support for the ``salt_length`` argument to the :class:`~cryptography.hazmat.primitives.asymmetric.padding.MGF1` constructor. The ``salt_length`` should be passed to :class:`~cryptography.hazmat.primitives.asymmetric.padding.PSS` instead. * Fix compilation on OS X Yosemite. * Deprecated ``elliptic_curve_private_key_from_numbers`` and ``elliptic_curve_public_key_from_numbers`` in favor of ``load_elliptic_curve_private_numbers`` and ``load_elliptic_curve_public_numbers`` on :class:`~cryptography.hazmat.backends.interfaces.EllipticCurveBackend`. * Added :class:`~cryptography.hazmat.primitives.interfaces.EllipticCurvePrivateKeyWithNumbers` and :class:`~cryptography.hazmat.primitives.interfaces.EllipticCurvePublicKeyWithNumbers` support. * Work around three GCM related bugs in CommonCrypto and OpenSSL. * On the CommonCrypto backend adding AAD but not subsequently calling update would return null tag bytes. * One the CommonCrypto backend a call to update without an empty add AAD call would return null ciphertext bytes. * On the OpenSSL backend with certain versions adding AAD only would give invalid tag bytes. * Support loading EC private keys from PEM. 0.5.4 - 2014-08-20 ~~~~~~~~~~~~~~~~~~ * Added several functions to the OpenSSL bindings to support new functionality in pyOpenSSL. * Fixed a redefined constant causing compilation failure with Solaris 11.2. 0.5.3 - 2014-08-06 ~~~~~~~~~~~~~~~~~~ * Updated Windows wheels to be compiled against OpenSSL 1.0.1i. 0.5.2 - 2014-07-09 ~~~~~~~~~~~~~~~~~~ * Add :class:`~cryptography.hazmat.backends.interfaces.TraditionalOpenSSLSerializationBackend` support to :doc:`/hazmat/backends/multibackend`. * Fix compilation error on OS X 10.8 (Mountain Lion). 0.5.1 - 2014-07-07 ~~~~~~~~~~~~~~~~~~ * Add :class:`~cryptography.hazmat.backends.interfaces.PKCS8SerializationBackend` support to :doc:`/hazmat/backends/multibackend`. 0.5 - 2014-07-07 ~~~~~~~~~~~~~~~~ * **BACKWARDS INCOMPATIBLE:** :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` no longer allows truncation of tags by default. Previous versions of ``cryptography`` allowed tags to be truncated by default, applications wishing to preserve this behavior (not recommended) can pass the ``min_tag_length`` argument. * Windows builds now statically link OpenSSL by default. When installing a wheel on Windows you no longer need to install OpenSSL separately. Windows users can switch between static and dynamic linking with an environment variable. See :doc:`/installation` for more details. * Added :class:`~cryptography.hazmat.primitives.kdf.hkdf.HKDFExpand`. * Added :class:`~cryptography.hazmat.primitives.ciphers.modes.CFB8` support for :class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES` and :class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES` on :doc:`/hazmat/backends/commoncrypto` and :doc:`/hazmat/backends/openssl`. * Added ``AES`` :class:`~cryptography.hazmat.primitives.ciphers.modes.CTR` support to the OpenSSL backend when linked against 0.9.8. * Added :class:`~cryptography.hazmat.backends.interfaces.PKCS8SerializationBackend` and :class:`~cryptography.hazmat.backends.interfaces.TraditionalOpenSSLSerializationBackend` support to the :doc:`/hazmat/backends/openssl`. * Added :doc:`/hazmat/primitives/asymmetric/ec` and :class:`~cryptography.hazmat.backends.interfaces.EllipticCurveBackend`. * Added :class:`~cryptography.hazmat.primitives.ciphers.modes.ECB` support for :class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES` on :doc:`/hazmat/backends/commoncrypto` and :doc:`/hazmat/backends/openssl`. * Deprecated :class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey` in favor of backend specific providers of the :class:`~cryptography.hazmat.primitives.interfaces.RSAPrivateKey` interface. * Deprecated :class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey` in favor of backend specific providers of the :class:`~cryptography.hazmat.primitives.interfaces.RSAPublicKey` interface. * Deprecated :class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey` in favor of backend specific providers of the :class:`~cryptography.hazmat.primitives.interfaces.DSAPrivateKey` interface. * Deprecated :class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey` in favor of backend specific providers of the :class:`~cryptography.hazmat.primitives.interfaces.DSAPublicKey` interface. * Deprecated :class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAParameters` in favor of backend specific providers of the :class:`~cryptography.hazmat.primitives.interfaces.DSAParameters` interface. * Deprecated ``encrypt_rsa``, ``decrypt_rsa``, ``create_rsa_signature_ctx`` and ``create_rsa_verification_ctx`` on :class:`~cryptography.hazmat.backends.interfaces.RSABackend`. * Deprecated ``create_dsa_signature_ctx`` and ``create_dsa_verification_ctx`` on :class:`~cryptography.hazmat.backends.interfaces.DSABackend`. 0.4 - 2014-05-03 ~~~~~~~~~~~~~~~~ * 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`. 0.3 - 2014-03-27 ~~~~~~~~~~~~~~~~ * 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. 0.2.2 - 2014-03-03 ~~~~~~~~~~~~~~~~~~ * Removed a constant definition that was causing compilation problems with specific versions of OpenSSL. 0.2.1 - 2014-02-22 ~~~~~~~~~~~~~~~~~~ * Fix a bug where importing cryptography from multiple paths could cause initialization to fail. 0.2 - 2014-02-20 ~~~~~~~~~~~~~~~~ * Added :doc:`/hazmat/backends/commoncrypto`. * Added initial :doc:`/hazmat/bindings/commoncrypto`. * Removed ``register_cipher_adapter`` method from :class:`~cryptography.hazmat.backends.interfaces.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 :doc:`/hazmat/backends/multibackend`. * Set default random for the :doc:`/hazmat/backends/openssl` to the OS random engine. * Added :class:`~cryptography.hazmat.primitives.ciphers.algorithms.CAST5` (CAST-128) support. 0.1 - 2014-01-08 ~~~~~~~~~~~~~~~~ * Initial release. .. _`master`: https://github.com/pyca/cryptography/
