I am new to python. I have read the documentation of requests module. I am working on validating the crt file of the website using python requests module. Instead of validating with the /etc/ssl/certs, i want to access it in the custom location. In my code, the crt file will be placed in the custom location. The Code will access the file and validates it. It works great for crt file of various https websites. But it fails on self signed ssl. In browser, the webpage(https://192.168.1.27/) gets opened. but it can't accessed via python request module. I have added the path in the code. It shows match error. How can i make that possible. I saw Validate SSL certificate using python But i can't solve it. Here's the sample code:
import requests
certpath = '/home/paulsteven/cert_check/Jeba.crt'
response = requests.get('https://192.168.1.27/', verify = certpath)
Error i got:
