[ Part 1 – Part 2 – Part 3 – Part 4 – Part 5 – Part 6 – Part 7 – Part 8 ]

What’s up guys?

Welcome to part two of the Python control server series.

In the first part of the series we made a simple plaintext control server. It allows you to run commands and control your systems from a distance.

This time we’re stepping it up and adding AES encryption to it.

Traffic Encryption

Since the plan is to eventually add more functionality to our server such as file transfer and reading documents over public networks, traffic encryption is definitely essential to the project.

Imagine you are downloading a file from your computer at home to your laptop using a hotel’s public wireless connection. It’s hard to feel safe about it without using some form of encryption.

For this and other reasons, we’ll be using pyAesCrypt to encrypt the connection to our server using AES both ways (server and client).

I have a few posts already on the topic. One specifically for recursive file encryption and another for encrypted data over the network.

This time, however, we’ll be using in-memory encryption stream to make sure our connection is safe from the server to the client and vice versa.
