I need to visit a site (https://*) that requires me to install two certificates in Firefox before I can visit it successfully. One I can export as a .p12 file (Client Certificate), and one is a .crt file (CA Certificate). If I try accessing this site without these certificates, I get a "failed handshake error".
How do I visit this site in Python? I was thinking of using mechanize. Thanks.
I'd suggest you use webdriver to automate Firefox. It has a Python interface too.

I am trying to open a link in "tor" using python. I just want to execute the code and it should start to visit that web page.
I haven't tried anything yet because I am new to this field of python. I know only the basics so kindly tolerate me.
You should use Selenium module for tor browser.
Installation
pip install tbselenium
Basic usage
from tbselenium.tbdriver import TorBrowserDriver
with TorBrowserDriver("/path/to/TorBrowserBundle/") as driver:
driver.get('https://check.torproject.org')
Note: TorBrowserDriver does not download Tor Browser Bundle (TBB) for you. You should download, extract TBB and provide its path when you initialize TorBrowserDriver.
Reference: Check
I am using requests library to complete communication with https websites. This works great, my only problem is that wireshark no longer captures plain text information in the "Decrypted SSL Data" tab as it does after following this instructional :
https://jimshaver.net/2015/02/11/decrypting-tls-browser-traffic-with-wireshark-the-easy-way/
Setup enviromental variable that allows chrome and firefox to store ssl keys in file, wireshark uses this file in real time.
Is their a way I can modify a simple https request script such as this :
import requests
resp = requests.get("https://www.google.com", allow_redirects=True)
to also store the ssl key into file as chrome and firefox do?
From what I understand about OpenSSL implementations that would do similar, you'd have to find the master secret and session key in memory - is this doable when running from cmd or practical?
This appears to be possible now with Requests.
I have set SSLKEYLOGFILE=secrets.log and then ran a request via requests.get() and secrets.log is now populated with TLS secrets. I am using requests v2.25.1 and urllib3 v1.26.3.
Apparently, it took a while for OpenSSL to provide APIs necessary to extract keying information, and then time for bindings to be created in pyOpenSSL to utilize those APIs and then for that to bubble up to urllib3.
See this issue for more details: https://github.com/psf/requests/issues/3674
openssl s_client -connect www.google.com:443 -showcerts
you will see all certs that google site uses.
Hi I am new to SSL and I am trying to connect to an IIS ASP.NET web server which has issued to me a unique .pfx certificate to verify me to the server.
Using a browser where I have installed the certificate I am able to connect the site where I have to upload a file on a daily basis.
I am trying to write a python script to do the same task. I have tried to use the Python Mechanize library.
While adding certificate I converted the .pfx file to .key and .cer PEM file so that it could be attached to add_client_certificate method, but later, I found out that IIS server accepts only .pfx certificate and there is no way to attach a .pfx certificate directly to the Mechanize browser instance.
Is there a way or another library where I can do this task?
You can use requests library
import requests
requests.get("https://your_server", cert=('client01.cer', 'client01.key'))
I am a client to a secured HTTPS server who has issued to me a password protected .pfx certificate to identify me to its system every-time. Using browser where I have installed the certificate (apparently only IE6 and previous versions works) i am able to log in and upload a file which i need to do on a daily basis. Right now am trying to write a Python script to do the same task and I am not sure if it is doable this way.
I am trying to use python mechanize library to connect to the server.
Using OpenSSL I have broken down the .pfx file into .key and .cer PEM files.
And I am using them as certificate for my python script.
Here is my code snippet
br = mechanize.Browser()
br.add_client_certificate(host,"I:/Key.key","I:/certificate.crt:")
whatever I tried it throws various SSL exception .. namely
SSL_CTX_use_certificate_chain_file
SSL_CTX_use_PrivateKey_file
Can anyone please tell me what possibly I could be doing wrong or if at all this is not the right approach.
I was able to get rid of errors by ways described in this link.
It didn't solve my purpose though because the server I was trying to connect is a IIS based server and it only accepts .pfx certificates.
For the last few days I have been trying ti install the Native Client SDK for chrome in Windows and/or Ubuntu.
I'm behind a corporate network, and the only internet access is through an HTTP proxy with authentication involved.
When I run "naclsdk update" in Ubuntu, it shows
"urlopen error Tunnel connection failed: 407 Proxy Authentication Required"
Can anyone please help ?
Try to download this file:
http://commondatastorage.googleapis.com/nativeclient-mirror/nacl/nacl_sdk/naclsdk_manifest2.json
It is the native client update summary, but in the URL I replaced the https with http. If you view the JSON file, you will see the different pepper_xx versions available. Use the links to download the one you want, but again replace https with http.
The naclsdk update tool is very difficult to use for those of us behind a strict firewall. It would be nice if Google provided a direct link to the latest SDK.
I got a solution-
not a direct one, though.
managed to use a program to redirect the HTTPS traffic through the HTTP proxy.
I used the program called "proxifier". Works great.
