Eullo

Eullo is a secure chat web application that provides end-to-end encryption using asymmetric encryption and RSA key pairs. This project utilizes various technologies such as Flask, LDAP, Angular, AWS, Terraform, and Socket.io. It aims to provide a secure and private communication platform for users.

Project Structure

The project is organized into the following components:

1. Eullo-Back

The Eullo-Back directory contains the backend logic of the application. It is built using Flask, a Python web framework. The backend handles user authentication, message encryption and decryption, and communication with the frontend.

2. Eullo-Front

The Eullo-Front directory contains the frontend logic of the application implemented using Angular, a popular JavaScript framework. The frontend provides a user-friendly interface for interacting with the chat application, displaying messages, managing contacts, and handling encryption and decryption.

3. Infrastructure

The Infrastructure directory contains the Terraform configuration files required to deploy the application on AWS EC2 instances. Terraform is an infrastructure as code tool that enables automated provisioning and management of cloud resources. It ensures the infrastructure is created and maintained consistently.
