Bumps pyopenssl from 25.3.0 to 26.0.0.

Changelog

Sourced from pyopenssl's changelog.

26.0.0 (2026-03-15)

Backward-incompatible changes: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  • Dropped support for Python 3.7.
  • The minimum cryptography version is now 46.0.0.

Deprecations: ^^^^^^^^^^^^^

Changes: ^^^^^^^^

  • Added support for using aws-lc instead of OpenSSL.
  • Properly raise an error if a DTLS cookie callback returned a cookie longer than DTLS1_COOKIE_LENGTH bytes. Previously this would result in a buffer-overflow. Credit to dark_haxor for reporting the issue. CVE-2026-27459
  • Added OpenSSL.SSL.Connection.get_group_name to determine which group name was negotiated.
  • Context.set_tlsext_servername_callback now handles exceptions raised in the callback by calling sys.excepthook and returning a fatal TLS alert. Previously, exceptions were silently swallowed and the handshake would proceed as if the callback had succeeded. Credit to Leury Castillo for reporting this issue. CVE-2026-27448
