PyCA cryptography 0.9 released
On behalf of all the contributors I am pleased to announce the release of PyCA/cryptography (https://github.com/pyca/cryptography) 0.9! Changelog: * Removed support for Python 3.2. This version of Python is rarely used and caused support headaches. Users affected by this should upgrade to 3.3+. * Deprecated support for Python 2.6. At the time there is no time table for actually dropping support, however we strongly encourage all users to upgrade their Python, as Python 2.6 no longer receives support from the Python core team. * Add support for the SECP256K1 elliptic curve. * Fixed compilation when using an OpenSSL which was compiled with the no-comp (OPENSSL_NO_COMP) option. * Support DER serialization of public keys using the public_bytes method of RSAPublicKeyWithSerialization, DSAPublicKeyWithSerialization, and EllipticCurvePublicKeyWithSerialization. * Support DER serialization of private keys using the private_bytes method of RSAPrivateKeyWithSerialization, DSAPrivateKeyWithSerialization, and EllipticCurvePrivateKeyWithSerialization. * Add support for parsing X.509 certificate signing requests (CSRs) with load_pem_x509_csr() and load_der_x509_csr(). * Moved cryptography.exceptions.InvalidToken to cryptography.hazmat.primitives.twofactor.InvalidToken and deprecated the old location. This was moved to minimize confusion between this exception and cryptography.fernet.InvalidToken. * Added support for X.509 extensions in Certificate objects. The following extensions are supported as of this release: - BasicConstraints - AuthorityKeyIdentifier - SubjectKeyIdentifier - KeyUsage - SubjectAlternativeName - ExtendedKeyUsage - CRLDistributionPoints - AuthorityInformationAccess - CertificatePolicies Note that unsupported extensions with the critical flag raise UnsupportedExtension while unsupported extensions set to non-critical are silently ignored. Read the X.509 documentation for more information. You can also view a more attractive version of the changelog here: https://cryptography.io/en/latest/changelog/ Master will be reopening for development of the tenth release shortly. -Paul Kehrer (reaperhulk) -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

We support Python 2.6-2.7, Python 3.3+, and PyPy. Changelog: * BACKWARDS INCOMPATIBLE: Elliptic Curve signature verification no longer returns True on success. This brings it in line with the interface’s documentation, and our intent. The correct way to use verify() has always been to check whether or not InvalidSignature was raised. * BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.7 and 10.8. * BACKWARDS INCOMPATIBLE: The minimum supported PyPy version is now 5.3. * Python 3.3 support has been deprecated, and will be removed in the next cryptography release. * Add support for providing tag during GCM finalization via finalize_with_tag(). * Fixed an issue preventing cryptography from compiling against LibreSSL 2.5.x. * Added key_size convenience methods for determining the bit size of a secret scalar for an elliptic curve. * Accessing an unrecognized extension marked critical on an X.509 object will no longer raise an UnsupportedExtension exception, instead an UnrecognizedExtension object will be returned. This behavior was based on a poor reading of the RFC, unknown critical extensions only need to be rejected on certificate verification. * The CommonCrypto backend has been removed. * MultiBackend has been removed. * Whirlpool and RIPEMD160 have been deprecated.

[Python-announce] PyCA cryptography 36.0.0 released
PyCA cryptography 36.0.0 has been released to PyPI. cryptography
includes both high level recipes and low level interfaces to common
cryptographic algorithms such as symmetric ciphers, asymmetric
algorithms, message digests, X509, key derivation functions, and much
more. We support Python 3.6+, and PyPy3.
(As a reminder, cryptography changed its versioning scheme with 35.0.
For more information see
https://cryptography.io/en/latest/api-stability/#versioning)
Changelog (https://cryptography.io/en/latest/changelog/#v36-0-0):
* FINAL DEPRECATION: Support for verifier and signer on our asymmetric
key classes was deprecated in version 2.1. These functions had an
extended deprecation due to usage, however the next version of
cryptography will drop support. Users should migrate to sign and
verify.
* The entire X.509 layer is now written in Rust. This allows alternate
asymmetric key implementations that can support cloud key management
services or hardware security modules provided they implement the
necessary interface (for example: EllipticCurvePrivateKey).
* Deprecated the backend argument for all functions.
* Added support for AESOCB3.
* Added support for iterating over arbitrary request attributes.
* Deprecated the get_attribute_for_oid method on
CertificateSigningRequest in favor of get_attribute_for_oid() on the
new Attributes object.
* Fixed handling of PEM files to allow loading when certificate and
key are in the same file.
* Fixed parsing of CertificatePolicies extensions containing legacy
BMPString values in their explicitText.
* Allow parsing of negative serial numbers in certificates. Negative
serial numbers are prohibited by RFC 5280 so a deprecation warning
will be raised whenever they are encountered. A future version of
cryptography will drop support for parsing them.
* Added support for parsing PKCS12 files with friendly names for all
certificates with load_pkcs12(), which will return an object of type
PKCS12KeyAndCertificates.
rfc4514_string() and related methods now have an optional
attr_name_overrides parameter to supply custom OID to name mappings,
which can be used to match vendor-specific extensions.
* BACKWARDS INCOMPATIBLE: Reverted the nonstandard formatting of email
address fields as E in rfc4514_string() methods from version 35.0. The
previous behavior can be restored with:
name.rfc4514_string({NameOID.EMAIL_ADDRESS: "E"})
* Allow X25519PublicKey and X448PublicKey to be used as public keys
when parsing certificates or creating them with CertificateBuilder.
These key types must be signed with a different signing algorithm as
X25519 and X448 do not support signing.
* Extension values can now be serialized to a DER byte string by
calling public_bytes().
* Added experimental support for compiling against BoringSSL. As
BoringSSL does not commit to a stable API, cryptography tests against
the latest commit only. Please note that several features are not
available when building against BoringSSL.
* Parsing CertificateSigningRequest from DER and PEM now, for a
limited time period, allows the Extension critical field to be
incorrectly encoded. See the issue for complete details. This will be
reverted in a future cryptography release.
* When OCSPNonce are parsed and generated their value is now correctly
wrapped in an ASN.1 OCTET STRING. This conforms to RFC 6960 but
conflicts with the original behavior specified in RFC 2560. For a
temporary period for backwards compatibility, we will also parse
values that are encoded as specified in RFC 2560 but this behavior
will be removed in a future release.

[Python-announce] PyCA cryptography 37.0.0 released
PyCA cryptography 37.0.0 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, asymmetric algorithms, message digests, X509, key derivation functions, and much more. We support Python 3.6+, and PyPy3. Changelog (https://cryptography.io/en/latest/changelog/#v37-0-0): * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.2. * BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL 2.9.x and 3.0.x. The new minimum LibreSSL version is 3.1+. * BACKWARDS INCOMPATIBLE: Removed signer and verifier methods from the public key and private key classes. These methods were originally deprecated in version 2.0, but had an extended deprecation timeline due to usage. Any remaining users should transition to sign and verify. * Deprecated OpenSSL 1.1.0 support. OpenSSL 1.1.0 is no longer supported by the OpenSSL project. The next release of cryptography will be the last to support compiling with OpenSSL 1.1.0. * Deprecated Python 3.6 support. Python 3.6 is no longer supported by the Python core team. Support for Python 3.6 will be removed in a future cryptography release. * Deprecated the current minimum supported Rust version (MSRV) of 1.41.0. In the next release we will raise MSRV to 1.48.0. Users with the latest pip will typically get a wheel and not need Rust installed, but check Installation for documentation on installing a newer rustc if required. * Deprecated CAST5, SEED, IDEA, and Blowfish because they are legacy algorithms with extremely low usage. These will be removed in a future version of cryptography. * Added limited support for distinguished names containing a bit string. * We now ship universal2 wheels on macOS, which contain both arm64 and x86_64 architectures. Users on macOS should upgrade to the latest pip to ensure they can use this wheel, although we will continue to ship x86_64 specific wheels for now to ease the transition. * This will be the final release for which we ship manylinux2010 wheels. Going forward the minimum supported manylinux ABI for our wheels will be manylinux2014. The vast majority of users will continue to receive manylinux wheels provided they have an up to date pip. For PyPy wheels this release already requires manylinux2014 for compatibility with binaries distributed by upstream. * Added support for multiple OCSPSingleResponse in a OCSPResponse. * Restored support for signing certificates and other structures in X.509 with SHA3 hash algorithms. * TripleDES is disabled in FIPS mode. * Added support for serialization of PKCS#12 CA friendly names/aliases in serialize_key_and_certificates() * Added support for 12-15 byte (96 to 120 bit) nonces to AESOCB3. This class previously supported only 12 byte (96 bit). * Added support for AESSIV when using OpenSSL 3.0.0+. * Added support for serializing PKCS7 structures from a list of certificates with serialize_certificates. * Added support for parsing RFC 4514 strings with from_rfc4514_string(). * Added AUTO to PSS. This can be used to verify a signature where the salt length is not already known. * Added DIGEST_LENGTH to PSS. This constant will set the salt length to the same length as the PSS hash algorithm. * Added support for loading RSA-PSS key types with load_pem_private_key() and load_der_private_key(). This functionality is limited to OpenSSL 1.1.1e+ and loads the key as a normal RSA private key, discarding the PSS constraint information. -Paul Kehrer (reaperhulk) ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com

We support Python 3.6+, and PyPy3. Changelog (https://cryptography.io/en/latest/changelog/#v37-0-1): * Fixed an issue where parsing an encrypted private key with the public loader functions would hang waiting for console input on OpenSSL 3.0.x rather than raising an error. * Restored some legacy symbols for older pyOpenSSL users. These will be removed again in the future, so pyOpenSSL users should still upgrade to the latest version of that package when they upgrade cryptography. -Paul Kehrer (reaperhulk) ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com

We support Python 3.6+, and PyPy3. Changelog (https://cryptography.io/en/latest/changelog/#v38-0-0): * Final deprecation of OpenSSL 1.1.0. The next release of cryptography will drop support. * We no longer ship manylinux2010 wheels. Users should upgrade to the latest pip to ensure this doesn’t cause issues downloading wheels on their platform. We now ship manylinux_2_28 wheels for users on new enough platforms. * Updated the minimum supported Rust version (MSRV) to 1.48.0, from 1.41.0. Users with the latest pip will typically get a wheel and not need Rust installed, but check Installation for documentation on installing a newer rustc if required. decrypt() and related methods now accept both str and bytes tokens. * Parsing CertificateSigningRequest restores the behavior of enforcing that the Extension critical field must be correctly encoded DER. See the issue for complete details. * Added two new OpenSSL functions to the bindings to support an upcoming pyOpenSSL release. * When parsing CertificateRevocationList and CertificateSigningRequest values, it is now enforced that the version value in the input must be valid according to the rules of RFC 2986 and RFC 5280. * Using MD5 or SHA1 in CertificateBuilder and other X.509 builders is deprecated and support will be removed in the next version. * Added additional APIs to SignedCertificateTimestamp, including signature_hash_algorithm, signature_algorithm, signature, and extension_bytes. * Added tbs_precertificate_bytes, allowing users to access the to-be-signed pre-certificate data needed for signed certificate timestamp verification. * KBKDFHMAC and KBKDFCMAC now support MiddleFixed counter location. * Fixed RFC 4514 name parsing to reverse the order of the RDNs according to the section 2.1 of the RFC, affecting method from_rfc4514_string(). * It is now possible to customize some aspects of encryption when serializing private keys, using encryption_builder(). * Removed several legacy symbols from our OpenSSL bindings. Users of pyOpenSSL versions older than 22.0 will need to upgrade. * Added AES128 and AES256 classes. These classes do not replace AES (which allows all AES key lengths), but are intended for applications where developers want to be explicit about key length. -Paul Kehrer (reaperhulk) ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com

We support Python 3.6+, and PyPy3. Changelog (https://cryptography.io/en/latest/changelog/#v39-0-0): * BACKWARDS INCOMPATIBLE: Support for OpenSSL 1.1.0 has been removed. Users on older versions of OpenSSL will need to upgrade. Note that this does not affect users of our wheels. * BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL < 3.5. The new minimum LibreSSL version is 3.5.0. Going forward our policy is to support versions of LibreSSL that are available in versions of OpenBSD that are still receiving security support. * BACKWARDS INCOMPATIBLE: Removed the encode_point and from_encoded_point methods onEllipticCurvePublicNumbers, which had been deprecated for several years. public_bytes() andfrom_encoded_point() should be used instead. * BACKWARDS INCOMPATIBLE: Support for using MD5 or SHA1 in CertificateBuilder, other X.509 builders, and PKCS7 has been removed. * BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.10 and 10.11, macOS users must upgrade to 10.12 or newer. * ANNOUNCEMENT: The next version of cryptography (40.0) will change the way we link OpenSSL. This will only impact 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 will no longer be respected. Instead, users will need to configure their builds as documented here. * Added support for disabling the legacy provider in OpenSSL 3.0.x. * Added support for disabling RSA key validation checks when loading RSA keys via load_pem_private_key(), load_der_private_key(), and private_key(). This speeds up key loading but is unsafe if you are loading potentially attacker supplied keys. * Significantly improved performance for ChaCha20Poly1305 when repeatedly calling encrypt or decrypt with the same key. * Added support for creating OCSP requests with precomputed hashes using add_certificate_by_hash(). * Added support for loading multiple PEM-encoded X.509 certificates from a single input via load_pem_x509_certificates(). -Paul Kehrer (reaperhulk) ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com

This will not impact you unless you are using cryptography to directly invoke OpenSSL’s C API. Note that these have never been considered a stable, supported, public API by cryptography, this note is included as a courtesy. * The X.509 builder classes now raise UnsupportedAlgorithm instead of ValueError if an unsupported hash algorithm is passed. * Added public union type aliases for type hinting: Asymmetric types: PublicKeyTypes, PrivateKeyTypes, CertificatePublicKeyTypes, CertificateIssuerPublicKeyTypes, CertificateIssuerPrivateKeyTypes SSH keys: SSHPublicKeyTypes, SSHPrivateKeyTypes, SSHCertPublicKeyTypes, SSHCertPrivateKeyTypes PKCS12: PKCS12PrivateKeyTypes PKCS7: PKCS7HashTypes, PKCS7PrivateKeyTypes Two-factor: HOTPHashTypes * Deprecated previously undocumented but not private type aliases in the cryptography.hazmat.primitives.asymmetric.types module in favor of new ones above. -Paul Kehrer (reaperhulk) ___ Python-announce-list mailing list -- python-announce-list@python.org To unsubscribe send an email to python-announce-list-le...@python.org https://mail.python.org/mailman3/lists/python-announce-list.python.org/ Member address: arch...@mail-archive.com
