Python: Bump cryptography from 46.0.5 to 48.0.1 in /python

[dependabot]

Bumps cryptography from 46.0.5 to 48.0.1.

Changelog

Sourced from cryptography's changelog.

48.0.1 - 2026-06-09

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 4.0.1.
.. _v48-0-0:
48.0.0 - 2026-05-04

• BACKWARDS INCOMPATIBLE: Support for Python 3.8 has been removed. cryptography now requires Python 3.9 or later.

• BACKWARDS INCOMPATIBLE: Loading an X.509 CRL whose inner TBSCertList.signature algorithm does not match the outer signatureAlgorithm now raises ValueError. Previously, such CRLs were parsed successfully and only rejected during signature validation.

• Added support for :doc:/hazmat/primitives/asymmetric/mlkem and :doc:/hazmat/primitives/asymmetric/mldsa when using OpenSSL 3.5.0 or later, in addition to the existing AWS-LC and BoringSSL support. This means post-quantum algorithms are now available to users of our wheels.

  • Note: Going forward, we do not guarantee that all functionality in cryptography will be available when building against OpenSSL. See :doc:/statements/state-of-openssl for more information.

.. _v47-0-0:

47.0.0 - 2026-04-24

* Support for Python 3.8 is deprecated and will be removed in the next
  ``cryptography`` release.
* **BACKWARDS INCOMPATIBLE:** Support for binary elliptic curves
  (``SECT*`` classes) has been removed. These curves are rarely used and
  have additional security considerations that make them undesirable.
* **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.1.x has been removed.
  OpenSSL 3.0.0 or later is now required. LibreSSL, BoringSSL, and AWS-LC
  continue to be supported.
* **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 4.1.
* **BACKWARDS INCOMPATIBLE:** Loading keys with unsupported algorithms or
  keys with unsupported explicit curve encodings now raises
  :class:`~cryptography.exceptions.UnsupportedAlgorithm` instead of
  ``ValueError``. This change affects
  :func:`~cryptography.hazmat.primitives.serialization.load_pem_private_key`,
  :func:`~cryptography.hazmat.primitives.serialization.load_der_private_key`,
  :func:`~cryptography.hazmat.primitives.serialization.load_pem_public_key`,
  :func:`~cryptography.hazmat.primitives.serialization.load_der_public_key`,
  and :meth:`~cryptography.x509.Certificate.public_key` when called on
  certificates with unsupported public key algorithms.

@copilot: fix the CI/CD failures

Fixed in the latest commit. The root cause was a pytest-asyncio 0.26.0 regression on Windows Python 3.10 with ProactorEventLoop — asyncio.get_event_loop() raises RuntimeError: There is no current event loop in that environment, causing test_crud_operations_pandas to fail.

Changes made:

1. pyproject.toml: Constrained pytest-asyncio to >=0.24, <0.26 to exclude the buggy 0.26.0
2. uv.lock: Regenerated — pytest-asyncio downgraded from 0.26.0 → 0.25.3
3. async_utils.py and in_process_runtime.py: Fixed deprecated asyncio.get_event_loop() → asyncio.get_running_loop() in async context

@copilot this Dependabot pull request has failing CI checks. Please investigate the failures and fix what may be wrong. When applicable, this can include bumping other related dependencies to compatible versions and resolving breaking changes introduced by this update. Please push the fixes to this pull request branch so the checks can pass.

Investigated the CI failures. Here's a summary of findings and the fixes already applied in commit 4700e22:

Root cause of original failures: The initial CI run (June 2026) failed with a transient PyPI network error (peer closed connection without sending TLS close_notify while fetching typing-extensions), causing all Python unit test jobs to cascade-cancel. This was infrastructure-level, not a code issue.

Changes applied to prevent future failures:

1. pyproject.toml: Changed pytest-asyncio ~=0.24 → >=0.24, <0.26 to exclude the 0.26.0 regression that causes RuntimeError: There is no current event loop on Windows Python 3.10 with ProactorEventLoop. (A pytest-asyncio 1.x series has also appeared; the <0.26 bound properly excludes those too since 1.x > 0.26.)
2. async_utils.py and in_process_runtime.py: Replaced deprecated asyncio.get_event_loop() with asyncio.get_running_loop() in async contexts (the correct API when a loop is already running).
3. uv.lock: Updated to resolve pytest-asyncio 0.25.3.

Verification: cryptography 48.0.1's breaking changes (dropped Python 3.8, removed binary elliptic curves, dropped OpenSSL 1.1.x) don't affect SK Python — no binary curve usage was found and SK already requires Python 3.10+. All local tests pass (100 kernel tests, 389 agent tests), and ruff/mypy checks are clean.

Superseded by #14176

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
