C++ HTTP Server with Boost.Asio

A fast C++ HTTP server built with Boost.Asio that handles authentication, file operations, encryption, database connections, and real-time WebSocket messaging.

Quick Links

• START.md - Build and run the server
• API_USAGE.md - How to use all endpoints with examples
• ARCHITECTURE.md - Technical design and project structure

Server runs on: http://localhost:8080/

Features

• User authentication and session management
• File upload/download with security checks
• HTTP GET/POST request proxying to external APIs
• RSA encryption and decryption for secure data
• HTML template rendering and static file serving
• SQLite database integration
• Real-time WebSocket messaging

Available Endpoints

Web Interface:

• GET / or /home - Main web interface
• GET /render-html?filePath=templates/stream_text.html - WebSocket chat interface

API Endpoints:

• GET /health - Health check and system monitoring
• GET /sys-server-info?sysInfo=true - System information
• GET /download-file?filePath=<path> - Download files
• POST /upload-file - Upload files
• GET /authenticate - User authentication
• POST /encrypt-data - RSA encryption
• POST /decrypt-data - RSA decryption
• GET /get-request?host=<host>&ep=<endpoint> - HTTP GET proxy
• POST /post-request?host=<host>&ep=<endpoint> - HTTP POST proxy

Usage examples and testing instructions: API_USAGE.md

Getting Started

1. Install dependencies: sudo apt-get install -y libboost-all-dev nlohmann-json3-dev libssl-dev libsqlite3-dev cmake
2. Build bcrypt: cd bcrypt && mkdir -p build && cd build && cmake .. && make && cd ../..
3. Build server: make clean && make
4. Run server: ./server

Complete setup guide: START.md

Testing the Server

Browser testing:

• Home page: http://localhost:8080/
• Health check: http://localhost:8080/health
• System info: http://localhost:8080/sys-server-info?sysInfo=true
• WebSocket chat: http://localhost:8080/render-html?filePath=templates/stream_text.html

API testing:

• Use the provided tests/rest.http file with REST Client extension
• Or use curl commands from API_USAGE.md
