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
