what do I do with the _cert object? Please provide some example use-cases, like using the certs in an api call

@ashupednekar, I will implement something using the same class as this project.

from contextlib import contextmanager
from tempfile import NamedTemporaryFile

from cryptography.hazmat.primitives.serialization import Encoding, PrivateFormat, NoEncryption
from cryptography.hazmat.primitives.serialization.pkcs12 import load_key_and_certificates


@contextmanager
def pfx_to_pem(pfx_path, pfx_password):
    pfx = open(pfx_path, 'rb').read()
    private_key, main_cert, add_certs = load_key_and_certificates(pfx, pfx_password.encode('utf-8'), None)

    with NamedTemporaryFile(suffix='.pem') as t_pem:
        with open(t_pem.name, 'wb') as pem_file:
            pem_file.write(private_key.private_bytes(Encoding.PEM, PrivateFormat.PKCS8, NoEncryption()))
            pem_file.write(main_cert.public_bytes(Encoding.PEM))
            for ca in add_certs:
                pem_file.write(ca.public_bytes(Encoding.PEM))
        yield t_pem.name

Use:

with pfx_to_pem(pfx_file_path, pfx_password) as cert:
    response = requests.get(
        url=url,
        headers=headers,
        cert=cert,
        verify=True
    )
    return response.text

Hello,
def .serial_number() is returning the incorrect serial number.
We can see inside the certificate posted in your git, after installing the certificate the serial number 168fda5ffe955cbd601bd563c3fd0165ef58cb7d is displayed and not the number 128805826665071774012132547883470073087342988157 assigned by the query.
Could you say if this is correct?
