./security/py-cryptography, Cryptographic recipes and primitives for Python

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 3.3.2, Package name: py38-cryptography-3.3.2, Maintainer: pkgsrc-users

cryptography is a package designed to expose cryptographic recipes
and primitives to Python developers. Our goal is for it to be your
"cryptographic standard library".

cryptography includes both high level recipes, and low level
interfaces to common cryptographic algorithms such as symmetric
ciphers, message digests and key derivation functions.

Log message:
py-cryptography, py-cryptography_vectors: updated to 3.3.2

3.3.2:
SECURITY ISSUE: Fixed a bug where certain sequences of update() calls when \ 
symmetrically encrypting very large payloads (>2GB) could result in an \ 
integer overflow, leading to buffer overflows. CVE-2020-36242
   2020-12-14 08:31:18 by Adam Ciarcinski | Files touched by this commit (5) | Package updated
Log message:
py-cryptography py-cryptography_vectors: updated to 3.3.1

3.3.1:
* Re-added a legacy symbol causing problems for older ``pyOpenSSL`` users.

3.3:
* **BACKWARDS INCOMPATIBLE:** Support for Python 3.5 has been removed due to
  low usage and maintenance burden.
* **BACKWARDS INCOMPATIBLE:** The
  :class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` and
  :class:`~cryptography.hazmat.primitives.ciphers.aead.AESGCM` now require
  64-bit to 1024-bit (8 byte to 128 byte) initialization vectors. This change
  is to conform with an upcoming OpenSSL release that will no longer support
  sizes outside this window.
* **BACKWARDS INCOMPATIBLE:** When deserializing asymmetric keys we now
  raise ``ValueError`` rather than ``UnsupportedAlgorithm`` when an
  unsupported cipher is used. This change is to conform with an upcoming
  OpenSSL release that will no longer distinguish between error types.
* **BACKWARDS INCOMPATIBLE:** We no longer allow loading of finite field
  Diffie-Hellman parameters of less than 512 bits in length. This change is to
  conform with an upcoming OpenSSL release that no longer supports smaller
  sizes. These keys were already wildly insecure and should not have been used
  in any application outside of testing.
* Updated Windows, macOS, and ``manylinux`` wheels to be compiled with
  OpenSSL 1.1.1i.
* Python 2 support is deprecated in ``cryptography``. This is the last release
  that will support Python 2.
* Added the
  \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.recover_data_ \ 
from_signature`
  function to
  :class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`
  for recovering the signed data from an RSA signature.

Log message:
py-cryptography py-cryptography_vectors: updated to 3.2.1

3.2.1 - 2020-10-27

Disable blinding on RSA public keys to address an error with some versions of \ 
OpenSSL.

3.2 - 2020-10-25

SECURITY ISSUE: Attempted to make RSA PKCS#1v1.5 decryption more constant time, \ 
to protect against Bleichenbacher vulnerabilities. Due to limitations imposed by \ 
our API, we cannot completely mitigate this vulnerability and a future release \ 
will contain a new API which is designed to be resilient to these for contexts \ 
where it is required. Credit to Hubert Kario for reporting the issue. \ 
CVE-2020-25659
Support for OpenSSL 1.0.2 has been removed. Users on older version of OpenSSL \ 
will need to upgrade.
Added basic support for PKCS7 signing (including SMIME) via \ 
:class:`~cryptography.hazmat.primitives.serialization.pkcs7.PKCS7SignatureBuilde \ 
r`.

3.1.1 - 2020-09-22

Updated Windows, macOS, and manylinux wheels to be compiled with OpenSSL 1.1.1h.

3.1 - 2020-08-26

BACKWARDS INCOMPATIBLE: Removed support for idna based :term:`U-label` parsing \ 
in various X.509 classes. This support was originally deprecated in version 2.1 \ 
and moved to an extra in 2.5.
Deprecated OpenSSL 1.0.2 support. OpenSSL 1.0.2 is no longer supported by the \ 
OpenSSL project. The next version of cryptography will drop support for it.
Deprecated support for Python 3.5. This version sees very little use and will be \ 
removed in the next release.
backend arguments to functions are no longer required and the default backend \ 
will automatically be selected if no backend is provided.
Added initial support for parsing certificates from PKCS7 files with \ 
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates` \ 
and \ 
:func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates` \ 
.
Calling update or update_into on \ 
:class:`~cryptography.hazmat.primitives.ciphers.CipherContext` with data longer \ 
than 231 bytes no longer raises an OverflowError. This also resolves the same \ 
issue in :doc:`/fernet`.
3.0 - 2020-07-20

BACKWARDS INCOMPATIBLE: Removed support for passing an \ 
:class:`~cryptography.x509.Extension` instance to \ 
:meth:`~cryptography.x509.AuthorityKeyIdentifier.from_issuer_subject_key_identifier`, \ 
as per our deprecation policy.

BACKWARDS INCOMPATIBLE: Support for LibreSSL 2.7.x, 2.8.x, and 2.9.0 has been \ 
removed (2.9.1+ is still supported).

BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.9, macOS users must upgrade \ 
to 10.10 or newer.

BACKWARDS INCOMPATIBLE: RSA \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.generate_private_key` no \ 
longer accepts public_exponent values except 65537 and 3 (the latter for legacy \ 
purposes).

BACKWARDS INCOMPATIBLE: X.509 certificate parsing now enforces that the version \ 
field contains a valid value, rather than deferring this check until \ 
:attr:`~cryptography.x509.Certificate.version` is accessed.

Deprecated support for Python 2. At the time there is no time table for actually \ 
dropping support, however we strongly encourage all users to upgrade their \ 
Python, as Python 2 no longer receives support from the Python core team.

If you have trouble suppressing this warning in tests view the :ref:`FAQ entry \ 
addressing this issue <faq-howto-handle-deprecation-warning>`.

Added support for OpenSSH serialization format for ec, ed25519, rsa and dsa \ 
private keys: \ 
:func:`~cryptography.hazmat.primitives.serialization.load_ssh_private_key` for \ 
loading and \ 
:attr:`~cryptography.hazmat.primitives.serialization.PrivateFormat.OpenSSH` for \ 
writing.

Added support for OpenSSH certificates to \ 
:func:`~cryptography.hazmat.primitives.serialization.load_ssh_public_key`.

Added :meth:`~cryptography.fernet.Fernet.encrypt_at_time` and \ 
:meth:`~cryptography.fernet.Fernet.decrypt_at_time` to \ 
:class:`~cryptography.fernet.Fernet`.

Added support for the :class:`~cryptography.x509.SubjectInformationAccess` X.509 \ 
extension.

Added support for parsing \ 
:class:`~cryptography.x509.SignedCertificateTimestamps` in OCSP responses.

Added support for parsing attributes in certificate signing requests via \ 
:meth:`~cryptography.x509.CertificateSigningRequest.get_attribute_for_oid`.

Added support for encoding attributes in certificate signing requests via \ 
:meth:`~cryptography.x509.CertificateSigningRequestBuilder.add_attribute`.

On OpenSSL 1.1.1d and higher cryptography now uses OpenSSL's built-in CSPRNG \ 
instead of its own OS random engine because these versions of OpenSSL properly \ 
reseed on fork.

Added initial support for creating PKCS12 files with \ 
:func:`~cryptography.hazmat.primitives.serialization.pkcs12.serialize_key_and_ce \ 
rtificates`.
