Backwards incompatible changes:
- Removed support for passing an Extension instance to
from_issuer_subject_key_identifier(), as per our deprecation policy.
- Support for LibreSSL 2.7.x, 2.8.x, and 2.9.0 has been removed (2.9.1+
is still supported).
- Dropped support for macOS 10.9, macOS users must upgrade to 10.10 or
newer.
- RSA generate_private_key() no longer accepts public_exponent values
except 65537 and 3 (the latter for legacy purposes).
- X.509 certificate parsing now enforces that the version field contains
a valid value, rather than deferring this check until version is
accessed.
Deprecations:
- 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.
Backwards incompatible changes:
- Support for Python 3.4 has been removed due to low usage and
maintenance burden.
- Support for OpenSSL 1.0.1 has been removed. Users on older version of
OpenSSL will need to upgrade.
- Support for LibreSSL 2.6.x has been removed.
- Reversed the order in which rfc4514_string() returns the RDNs as
required by RFC 4514.
Note: The first three changes should have no impact on Nixpkgs as we
already removed Python 3.4 and OpenSSL 1.0.1. Additionally we don't
support LibreSSL for this package.
Changelog:
https://cryptography.io/en/latest/changelog/#v2-8
Important changes:
- Deprecated support for OpenSSL 1.0.1. Support will be removed in
cryptography 2.9.
- cryptography no longer depends on asn1crypto.
- Added support for Python 3.8.
Changelog:
https://cryptography.io/en/latest/changelog/#v2-7
Important changes:
- BACKWARDS INCOMPATIBLE: We no longer distribute 32-bit manylinux1
wheels. Continuing to produce them was a maintenance burden.
- BACKWARDS INCOMPATIBLE: Removed the
cryptography.hazmat.primitives.mac.MACContext interface.
The CMAC and HMAC APIs have not changed, but they are no longer
registered as MACContext instances.
Changelog:
https://cryptography.io/en/latest/changelog/#v2-6-1
Important changes:
- BACKWARDS INCOMPATIBLE: Removed
cryptography.hazmat.primitives.asymmetric.utils.encode_rfc6979_signature
and
cryptography.hazmat.primitives.asymmetric.utils.decode_rfc6979_signature,
which had been deprecated for nearly 4 years. Use
encode_dss_signature() and decode_dss_signature() instead.
- BACKWARDS INCOMPATIBLE: Removed cryptography.x509.Certificate.serial,
which had been deprecated for nearly 3 years. Use serial_number
instead.
This should make the management easier. The package cryptography_vectors
contains the test vectors for cryptography and should therefore always
have the same version. By linking the version of cryptography_vectors to
cryptography, this simply cannot be forgotten.
Changelog:
https://cryptography.io/en/latest/changelog/#v2-5
Important changes:
- BACKWARDS INCOMPATIBLE: U-label strings were deprecated in version
2.1, but this version removes the default idna dependency as well.
- BACKWARDS INCOMPATIBLE: The minimum supported PyPy version is now 5.4.
Changelog:
https://cryptography.io/en/latest/changelog/#v2-4-2
Important changes:
- BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL 2.4.x.
- Deprecated OpenSSL 1.0.1 support. OpenSSL 1.0.1 is no longer supported
by the OpenSSL project. At this time there is no time table for
dropping support, however we strongly encourage all users to upgrade
or install cryptography from a wheel.
