scapy does not support cryptography modules past cryptography 41.0.7

[russdm]

Brief description

Additional modules needed to run scapy are being removed or rewritten from the hazmat directory.
file path: C:\Users\username\AppData\Local\Programs\Python\Python312\Lib\site-packages\cryptography\hazmat\backends\openssl\

So far these modules have disappeared as of cryptography 42.0.2 in the above directory:
ec.py
rsa.py
utils.py
cmac.py

This causes reference errors in the scapy cert.py library accessing the InvalidSignature class.
from cryptography.hazmat.backends.openssl.ec import InvalidSignature

Scapy version

2.5.0

Python version

3.12.1

Operating system

Windows 11

Additional environment information

Missing modules in cryptography

How to reproduce

Update to cryptography 42.0.2

Actual result

from scapy.layers.tls.all import *
from cryptography.hazmat.backends.openssl.ec import InvalidSignature #from cryptography.hazmat.backends.openssl.ec import InvalidSignature
ModuleNotFoundError: No module named 'cryptography.hazmat.backends.openssl.ec'

Expected result

Module to be present or a work around to remove this functionality in the code as deprecated.

This is fixed on master. See #4236

@gpotter2 you've only fixed this in master branch which currently has no ETA for a release since it's blocked by #4196

Please can a patch version of 2.5.x be released which pins the dependency to cryptography<42 ? As it stands the version of scapy on PyPI is broken because of this.

It works if you use the master from github, just patch it yourself and copy and paste the files from the scapy module on github into the C:\Users\username\AppData\Local\Programs\Python\Python312\Lib\site-packages\scapy folder until your cryptography module errors disappear.
