+# Project Restructuring Summary
+
+## Overview
+This document summarizes all the changes made to restructure and improve the Keylogger project.
+
+## Date
+January 22, 2026
+
+## Changes Made
+
+### 1. Directory Structure Reorganization
+
+**Before:**
+```
+/
+├── key_logger.py (root level)
+├── web_server.py (root level)
+├── manual.sh (root level)
+├── ngrok binaries (~72MB)
+└── ...
+```
+
+**After:**
+```
+/
+├── src/
+│   ├── __init__.py
+│   ├── keylogger.py
+│   └── server.py
+├── config/
+│   ├── config.json.example
+│   └── .env.example
+├── logs/
+│   └── .gitkeep
+├── docs/
+│   ├── INSTALLATION.md
+│   └── manual.sh
+├── setup.sh
+└── ...
+```
+
+### 2. Code Improvements
+
+#### src/keylogger.py (formerly key_logger.py)
+- **Object-oriented design**: Wrapped functionality in `KeyLogger` class
+- **Configuration management**: Added support for JSON config files
+- **Command-line interface**: Added argparse for flexible CLI options
+- **Better error handling**: Improved exception handling and user feedback
+- **SSL verification**: Enabled SSL certificate verification by default
+- **Modular design**: Separated concerns into methods
+
+#### src/server.py (formerly web_server.py)
+- **Security improvements**:
+  - Required explicit authentication credentials (no hardcoded defaults)
+  - Used `secrets.compare_digest()` for timing-attack resistant password comparison
+  - Added Flask secret key for secure session management
+  - Implemented file size limits to prevent memory exhaustion (10MB limit)
+  - Added better error handling for file operations
+- **Configuration management**: Support for JSON config and environment variables
+- **Command-line interface**: Added argparse for flexible deployment
+- **Improved HTML template**: Added warnings and better styling
+
+### 3. Configuration Management
+
+#### config/config.json.example
+```json
+{
+    "keylogger": {
+        "log_file_path": "logs/keylog.txt",
+        "batch_size": 10,
+        "server_url": "https://your-ngrok-url.ngrok-free.app"
+    },
+    "web_server": {
+        "log_file_path": "logs/keylog.txt",
+        "host": "0.0.0.0",
+        "port": 5000,
+        "debug": false
+    }
+}
+```
+
+#### config/.env.example
+```bash
+WEB_SERVER_USERNAME=admin
+WEB_SERVER_PASSWORD=change_this_password
+FLASK_DEBUG=False
+FLASK_SECRET_KEY=generate_random_secret_key_here
+```
+
+### 4. Security Fixes
+
+1. **Removed hardcoded credentials**: Moved to environment variables
+2. **Timing attack prevention**: Used `secrets.compare_digest()` for password comparison
+3. **Flask secret key**: Added for secure session management
+4. **Memory exhaustion prevention**: Limited log file reading to 10MB
+5. **SSL certificate verification**: Enabled by default with option to disable
+6. **Strong password enforcement**: Warning for weak passwords
+7. **No default credentials**: Requires explicit configuration
+
+### 5. Repository Cleanup
+
+- **Removed ~72MB of ngrok binaries** (5 files)
+- **Removed old Python scripts** (key_logger.py, web_server.py)
+- **Updated .gitignore**:
+  - Added `ngrok-*.zip` and `ngrok-*.tgz`
+  - Added `config/config.json` and `config/.env`
+  - Added `logs/*` (except `.gitkeep`)
+
+### 6. Documentation
+
+#### README.md
+- Complete rewrite with proper structure
+- Added quick start guide
+- Added detailed usage instructions
+- Added security warnings and legal disclaimers
+- Added contribution guidelines
+
+#### docs/INSTALLATION.md
+- Comprehensive installation guide
+- Troubleshooting section
+- Configuration examples
+- Best practices
+
+### 7. Setup Automation
+
+#### setup.sh
+- Automated setup script
+- Virtual environment creation
+- Dependency installation
+- Configuration file setup
+- User-friendly output with instructions
+
+### 8. Python Package Structure
+
+- Added `src/__init__.py` to make it a proper Python package
+- Version information included
+- Better code organization
+
+## Security Scan Results
+
+### Code Review
+- Identified 5 security issues
+- All issues addressed and fixed
+
+### CodeQL Analysis
+- **0 alerts** - No security vulnerabilities found
+- Clean bill of health
+
