How to use a .pfx file with Python requests – also works with .p12 files
import contextlib
import OpenSSL.crypto
import os
import requests
import ssl
import tempfile
@contextlib.contextmanager
def pfx_to_pem(pfx_path, pfx_password):
''' Decrypts the .pfx file to be used with requests. '''
with tempfile.NamedTemporaryFile(suffix='.pem') as t_pem:
f_pem = open(t_pem.name, 'wb')
pfx = open(pfx_path, 'rb').read()
p12 = OpenSSL.crypto.load_pkcs12(pfx, pfx_password)
f_pem.write(OpenSSL.crypto.dump_privatekey(OpenSSL.crypto.FILETYPE_PEM, p12.get_privatekey()))
f_pem.write(OpenSSL.crypto.dump_certificate(OpenSSL.crypto.FILETYPE_PEM, p12.get_certificate()))
ca = p12.get_ca_certificates()
if ca is not None:
for cert in ca:
f_pem.write(OpenSSL.crypto.dump_certificate(OpenSSL.crypto.FILETYPE_PEM, cert))
f_pem.close()
yield t_pem.name
# HOW TO USE:
# with pfx_to_pem('foo.pem', 'bar') as cert:
# requests.post(url, cert=cert, data=payload)
