Introduction

Welcome to the readme file for the Socket Programming-project!

This project focusses on the security of transfering live video through socket programming using Python 3.12. This project consists of three seperate prototypes using different approached to encryption:
• Prototype 1 (ALE_Client.py & ALE_Server.py): Application Level Encryption (ALE)
• Prototype 2 (TLS_Client.py & TLS_Server.py): Transport Layer Security (TLS)
• Prototype 3 (ALE_TLS_Client.py & ALE_TLS_Server.py): ALE + TLS

This readme file will provide instruction on how to use each prototype in a ubuntu 20.04 environment:

Prototype 1 (ALE_Client.py & ALE_Server.py): Application Level Encryption (ALE)

1. Make sure to use two seperate terminals
2. In both terminals to the folder of this using the linux commandline. cd {path to project}
3. Only use this step if you want a fresh venv for this project! Otherwise skip to step 4.
   3.a Create a new virtualenv by using virtualenv venv
   3.b Activate the virtualenv by using source ./venv/bin/activate (note: this command is different for windows machines)
   3.c install dependecies of this project via pip install -r requirements.txt
   
4. In both terminals activate the the virtualenv by using source ./venv/bin/activate (note: this command is different for windows machines)
5. Run the server socket using python ALE_Server.py
6. Run the client socket using python ALE_Client.py
7. Video transmitted should be visible, press 'q' to exit and close both sockets.

Prototype 2 (TLS_Client.py & TLS_Server.py): Transport Layer Security (TLS)

1. For this prototype a root self signed certificate and private key must be used, follow the steps of: https://gist.github.com/cecilemuller/9492b848eb8fe46d462abeb26656c4f8 and place the files in the keys folder
2. Make sure to use two seperate terminals
3. In both terminals to the folder of this using the linux commandline. cd {path to project}
4. Only use this step if you want a fresh venv for this project! Otherwise skip to step 5.
   4.a Create a new virtualenv by using virtualenv venv
   4.b Activate the virtualenv by using source ./venv/bin/activate (note: this command is different for windows machines)
   4.c install dependecies of this project via pip install -r requirements.txt
   
5. In both terminals activate the the virtualenv by using source ./venv/bin/activate (note: this command is different for windows machines)
6. Run the server socket using python TLS_Server.py
7. Run the client socket using python TLS_Client.py
8. Video transmitted should be visible, press 'q' to exit and close both sockets.
