build(deps-dev): update cryptography requirement from >=49.0.0 to >=50.0.1

[dependabot]

User description

Updates the requirements on cryptography to permit the latest version.

Changelog

Sourced from cryptography's changelog.

50.0.1 - 2026-08-25

* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 4.0.2.
.. _v50-0-0:
50.0.0 - 2026-07-31

• SECURITY ISSUE: :func:~cryptography.hazmat.primitives.serialization.pkcs7.pkcs7_decrypt_der and its PEM and S/MIME variants no longer expose distinguishable errors or timing when unwrapping a RecipientInfo's encryptedKey, which could act as a Bleichenbacher oracle for callers that decrypt untrusted messages. A random key is now substituted on failure, as described in :rfc:3218. Credit to @​X1AOxiang for reporting the issue. CVE-2026-69247
• Deprecated Diffie-Hellman key exchange over finite fields (FFDH). Everything FFDH is deprecated, including the types in cryptography.hazmat.primitives.asymmetric.dh and loading FFDH keys or parameters with the key loading APIs. Users should migrate to a more modern key exchange algorithm.
• Added xof() class methods to :class:~cryptography.hazmat.primitives.hashes.SHAKE128 and :class:~cryptography.hazmat.primitives.hashes.SHAKE256 for constructing algorithm instances configured for use with :class:~cryptography.hazmat.primitives.hashes.XOFHash.
• The :mod:X.509 verification <cryptography.x509.verification> APIs are now considered stable and are subject to our API stability policy.
• Added the :doc:/cobblestone recipe, an implementation of the Cobblestone-128 and Cobblestone-256 instantiations of the C2SP chunked-encryption specification <https://c2sp.org/chunked-encryption>_ for streaming authenticated encryption of large messages.
• Parsing a Signed Certificate Timestamp list now rejects encodings that carry trailing bytes after the list or after an individual SCT, instead of silently ignoring them.
• Added support for using :class:~cryptography.x509.Name as a field type in the :doc:/hazmat/asn1/index module.
• Loading a public key or an EC private key now rejects DER where the subjectPublicKey (or EC publicKey) BIT STRING declares a non-zero number of unused bits, instead of silently ignoring it.
• Parsing a CRL entry's InvalidityDate extension now rejects a GeneralizedTime that carries fractional seconds or another non-DER form, matching the strict encoding already required for every other X.509 time field.
• :func:~cryptography.x509.ocsp.load_der_ocsp_request and :func:~cryptography.x509.ocsp.load_der_ocsp_response now reject a request or response whose version field is not v1, the only version defined by RFC 6960, matching the version validation already performed when loading

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 7 - Partially compliant Compliant requirements: typer requirement already permits >=0.24.1 (pyproject.toml pins typer>=0.27.1), though this was not changed by this PR. Non-compliant requirements: This PR does not touch the typer requirement at all; it updates the cryptography requirement instead, so it does not implement the ticket's change. Requires further human verification: Confirm whether the linked ticket (typer update) is the correct ticket for this cryptography dependency bump, or if the wrong ticket was attached.
