The Virtual Bank Project

• The repo name translates to Bank, it is encrpyted using the key "gotcha bitch"
• (88xiwfTl9kAcPccoELmUUQ==) => [gotcha] => (Bank)
• A similar key based Symmetric Encryption Algorithm is used in this project.

Introduction

• Welcome to the "V Bank" Banking Management System!
• This project is a research project that aims to provide a comprehensive banking management solution.
• The system utilizes a client-server architecture, allowing for multiple clients to connect and interact with the system simultaneously.
• The system is designed to be a complete banking management system with all necessary functionalities included such as account creation, money transfer, cash withdrawal, account management, and much more.
• The program is based on modern online banking systems and can handle multiple clients at once without much of a problem.
• It can run as a proper server and client based system (on multiple computers at once) if configured correctly.

Basic Requirements

• A Banking system mainly focused on the operations like adding new customers to the bank, depositing, withdrawing, and transferring money.

Add-ons

• A proper bank system with loaning feature made in a similar fashion to what normal banks do.
• Different account types such as savings or current.
• A proper encryption-based data transfer for security.
• An ATM made using python, that works synchronously with these bank accounts.

Technical Overview

• The system uses a custom implementation of the TCP/IP protocol for communication between clients and the server.
• On the server side, Winsock 2.0, a Windows Sockets API, is used for handling network communications.
• On the client side, QTCP, a QT-based library for creating TCP/IP clients and servers, is used.
• Encryption is done using the AES algorithm, which is a symmetric-key algorithm that uses the same key for both encryption and decryption.
• The server uses SQLite3 as the database management system, providing a lightweight and easy to use solution for data storage.
• Python is used for handling some small tasks such as money withdrawals, providing a versatile and powerful scripting language for the system.
• The user interface of the system is built using QT's built-in XML, which provides a simple and efficient way to create the front-end.
• The codebase of the project consists of around 4000 lines of plain code, making it a relatively small yet complete solution for banking management.
• Utilizes OOP concepts such as Abstract Classes, Singleton Class, Static Member, Constants, Static and Dynamic Type binding, Inheritance, Encapsulation, Overriding, Polymorphism, and Composition.

Dependencies

• QT Creator must be installed on every client machine.
• QMake compilation agent must also be installed, which is used for building the project.
• A C++ compiler with CMake integration is also required, as the project uses CMake as the build system.

Setup

1. Clone the repository from the git.
2. Open the project in QT Creator.
3. Build the project using the QMake compilation agent.
4. For the Server open the server folder.
5. Build the C++ files.
6. Run the Server.
7. Now you can run the QT client.

Additional Features

• Server-Client Model using Socket Programming.
• Multithreading.
• Symmetric Encryption during datatransfer.

A Random Snippet

• There are many more pages and features not shown here, if you are genuinely interested in it you can fork the repo and check it out yourself.

Known Issues

• The TCP/IP protocol implementation in the project is a custom implementation, and as such, it may fail to run properly once every ten times.
• This was made as a research project, and as such, it might not be a complete solution for banking management systems, because of that it contains some bugs and might not work on every system because of configuration issues.

Future Plans

• The project is currently in a working state, but it is not complete. And from the contributors side, it is not going to be updated anymore.
• The project is now open source, and anyone is free to contribute to it and make it better.

Conclusion

• This project serves as a comprehensive example of how a banking management system can be developed using C++, QT Creator, and various other technologies and how can such a system be built from scratch.
• The system provides a complete solution for banking management, with all the necessary functionalities included, and can serve as a starting point for further development and customization.
