This project implements a secure Server-Client application for basic banking operations, designed with TLS/SSL encryption to protect user data during transactions. The server and client can handle tasks like Account creation, Login, Balance checks, Deposits, and Withdrawals.
- Makefile: Compiles the Server and client code and generates SSL certificates automatically.
- server.cpp: Contains the server logic for handling client requests and user account management.
- client.cpp: Provides a client interface to interact with the server for various banking functions.
- auth.txt / auth_backup.txt: Stores user data persistently, with periodic backups.
- Ubuntu OS
- OpenSSL Library:
sudo apt updatesudo apt install libssl-dev - C++ Compiler: GCC and C++17.
- Directory Creation:
mkdir -p src build/bin certs
mv Bank_client.cpp src/
mv Bank_Server.cpp src/
-
Compile the Project:
-
Run the Makefile to compile both the server and client programs, as well as generate the necessary SSL certificates: make
-
This will generate:
- server and client binaries
- server_cert.pem and server_key.pem for Server SSL communication
- public_key.pem and private_key.pem for client-Server secure data handling
- Running the Application
- Start the Server:
- Run the server program with: ./bank
- The server listens on localhost at port 8080 for client connections.
- Start the Client:
- Open a new terminal session and run: ./atm
- The client connects to the server on 127.0.0.1 (localhost) at port 8080.
- Logs errors and provides user feedback on all operations.
- To remove generated binaries and certificates: make clean
Upon compilation, auth.txt and auth_backup.txt files are used to manage and backup user data. Ensure they are handled securely, especially in production.
