I’ve create a RogueAP with my RaspberryPI. With this cool tool i’m able to intercept HTTP authentification : https://github.com/DanMcInerney/net-creds

For the next level i want to try to intercept HTTPS.

My thoeriy is :

The client use the public certificate of the server to encrypt the data and the server use the private key to decode and read the data

If i get the private key of the server i’m able to read HTTPS ?

Exemple : i host the website : www.easyhack.com i install HTTPS with the certbot on this website i download the private key generated by certbot i start wireshark and i search create a pcap

how to use the cert to decode the HTTPS My thoery is exact ? I’m just curious not a brillant specialist

what do you think about that ? (sorry for my english, i’m french)
