Mango Messenger Bachelor's Thesis

What is all about

Mango Messenger is an opensource instant messaging system such that implemented using ASP NET 5 framework as REST API backend along with Angular framework as frontend. In general, current project is considered to be a diploma project in order to get bachelor's degree of computer science. However, now it is considered to be a just example of ASP .NET Core API implementation using best practices in terms of architecture etc., where it is possible to apply different software development approaches and to see how it works on different environments such as Azure, Heroku etc. Moreover, a few cryptographical concepts are implemented such as DH key exchange that can be applied in order to implement secret chats in feature. Current repository contains a LeTeX documentation for the diploma project entitled Mango Messenger and available online as PDF.
