chore(deps): Bump pyopenssl from 26.2.0 to 26.4.0

[dependabot]

Bumps pyopenssl from 26.2.0 to 26.4.0.

Changelog

Sourced from pyopenssl's changelog.

26.4.0 (2026-08-01)

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

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

Changes: ^^^^^^^^

• Maximum supported cryptography version is now 50.x.

26.3.0 (2026-06-12)

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

• Dropped support for Python 3.8.
• The minimum cryptography version is now 49.0.0.
• Removed deprecated OpenSSL.crypto.X509Req, OpenSSL.crypto.dump_certificate_request, and OpenSSL.crypto.load_certificate_request. cryptography.x509 should be used instead.
• OpenSSL.SSL.Connection.set_session now raises ValueError if the Session was obtained from a Connection that was using a different Context than this one. OpenSSL requires (but does not verify) that sessions only be re-used with a compatible SSL_CTX, so this contract is now enforced.

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

• Deprecated OpenSSL.crypto.PKey.generate_key and OpenSSL.crypto.PKey.check. The key generation and loading APIs in cryptography should be used instead.
• Deprecated OpenSSL.crypto.dump_privatekey. The serialization APIs on cryptography private key types should be used instead.
• Deprecated all the mutable APIs on OpenSSL.crypto.X509: set_version, set_pubkey, sign, set_serial_number, gmtime_adj_notAfter, gmtime_adj_notBefore, set_notBefore, set_notAfter, set_issuer, and set_subject. cryptography.x509.CertificateBuilder should be used instead.
• Deprecated OpenSSL.SSL.Context.set_passwd_cb. Users should decrypt and load their private keys themselves, with cryptography's key loading APIs, and then call OpenSSL.SSL.Context.use_privatekey.
• Deprecated OpenSSL.crypto.X509Name, as well as the remaining APIs that consume or return it: OpenSSL.crypto.X509.get_issuer, OpenSSL.crypto.X509.get_subject, and OpenSSL.SSL.Context.set_client_ca_list. The APIs in cryptography.x509 should be used instead.

Changes: ^^^^^^^^

• OpenSSL.SSL.Connection.get_client_ca_list now takes an as_cryptography keyword-argument. When True is passed then cryptography.x509.Name are returned, instead of OpenSSL.crypto.X509Name. In the future, passing False (the default) will be deprecated.
