RSA-communication-socketio

This is a RSA Communicatio implementation using websockets from Socketio in python without any UI.

Specs:

• Keys of 2048 bits for both Encryption and Signature.
• ECB encryption mode (Although this could be improved).
• Supports n length of message as input.
• Fast Encpryption and Decryption.
• Implemented as websockets, could be easily changed for a web application usage, or for remote comms with a dedicated server and domain.
• Supports as many users as needed, but comms are 1-1 private.

Running the code:

First of all download/clone the repository on your desired directory, then you have to install some dependencies if you dont have them:

  pip install "python-socketio" "python-socketio[client]" "gunicorn"

• Server: To run the server move to the server folder, then run in a command line

    gunicorn --threads 50 main:app

  and it should start in port 8000 over the localhost

• Client: Now to run the client, on a different command line, go to the client folder and run

    python3 main.py <username>

  Note: Sometimes python3 command will not be avialable on your machine, check if py, pythonor py3are available if none of them are, then check if you have a python distribution installed and if you have check that the PATH of the distribution is correct.

  This will start a new client on the chat, if you want two or more just open more command lines and run the same command with different usernames.

  Note that there is also an available docker environment version either here or from docker pull dleyvacastro/rsasocketio. When downloaded you can run: docker run -d -t --name rsasocketio dleyvacastro/rsasocketio to create the container and then use commands like docker exec -it rsasocketio /somefolder/Client/main.py <username> to get the instance running, from there you will be able to run the proyect with the commands described above.
