PKI Certificates and RSA

38664Project #2 PKI Certificates and RSA
Write a Python script that implements PKI Certificates and RSA Authentication.

Generate a fake root certificate whose public key will act as your Certificate Authority for both parties.

Using the Fake Root, generate a certificate for each party using openssl (or something similar) using RSA-1024. Keep the private key for each party locally.

You can (and should) use libraries for encryption and key generation.

The session key can be hardcoded string (unless you are feeling adventurous).

You can have both parties on the same computer if you like but I would like you to have two processes that communicate over IP (using a socket and localhost). This is a networking class after all. There are plenty of libraries for doing this in Python or whatever you choose to use.

General Steps:
1. A reads A’s certificate from file. B reads B’s certificate
2. A and B exchange Certificates
3. A and B verify the identity of the certificates with the local CA (file)
4. A encrypts a unique number and their ID with B’s public key from certificate
5. B encrypts A’s number and a new number with A’s public key from certificate
6. A responds with the second number encrypted with B’s public key
7. A then sends a session key encrypted with A’s private key and B’s public key

I have attached some work from this project. We were off to the right start, so hopefully, this is helpful.
