Secure Messaging Repository System 🔐 📧

University Project ( Class: Security )

Problem

The objective of this project is to develop a system enabling users to ex-change messages asynchronously. Messages are sent and received through a non-trustworthy central repository, which keeps messages for users until they fetch them. The resulting system is composed by a Rendezvous Point, or Server, and several clients exchanging messages. The system should be designed to support the following security features:

• Message confidentiality, integrity and authentication
• Message delivery confirmation
• Identity preservation

Requirements

You have two option for install requirements:

1. (Python3 required) pip install -r ./requirements.txt

2. (virtualenv required) ./create_venv.sh source venv/bin/activate

You will also need a middleware of the Portuguese Citizenship Card because to ensure identity preservation all messages are signed using CC's Authentication Key.

Deployment

First, it is needed to run the server:

 	# On project dir
	python Server/server.py 

After, for open one client interface, it is needed to plug the Citizenship Card and next:

 	# On project dir
	python Client/client.py
