Purpose

The aim of this project is to learn and improve aspects about the software development, design patterns, some technologies used in the market currently and cripthography techniques to protect the information, with application of all of them in a real chat app. These involve a previous research about the history of the most well-known chats and the common communication and security architectures used for chat apps including advantajes and disavantages for each one. When the chat functionalities were defined, the software architectures were specified too with reference to the investigation in order to develop the latter.

Description

MySocket is an open-source web chat app that allows the communication between users throghout messages in different ways. The backend holds a RESTful API to accomplish user session functionalities and the Websocket technology to exchange chat rooms and messages, getting instant messaging.

MySocket implements a mixed crypto system so as to protect the data. The algorithms used to achieve this level have been:

• AES (256 bits)
• RSA (2048 bits)
• SHA-3 (512 bits)
