🚀 Getting Started

🛠️ Prerequisites

• Rust (latest stable)
• Cargo

📦 Installation

Clone the repository:

git clone https://github.com/austinsonger/rustwall.git
cd rustwall

Build and run:

cargo run

By default, the server will start on http://localhost:8080.

⚙️ Configuration

Edit the Config struct in src/config.rs to adjust settings such as:

• ⏲️ Session timeout
• 🚦 Rate limiting thresholds
• 🌐 Allowed origins

📝 Usage

🖥️ CAPTCHA System

Visit http://localhost:8080/captcha to see the analog clock CAPTCHA in action.

🔗 API Endpoints

CAPTCHA API

• POST /api/captcha/new – Generate a new CAPTCHA challenge
• POST /api/captcha/verify – Verify a user's response

Security API

• GET /api/security/status – Get system security status
• POST /api/security/emergency-shutdown – Trigger emergency shutdown
• GET /api/security/canary – Get warrant canary status

Example requests:

# Generate new CAPTCHA
curl -X POST http://localhost:8080/api/captcha/new

# Check security status
curl -X GET http://localhost:8080/api/security/status

# Get warrant canary
curl -X GET http://localhost:8080/api/security/canary

🧩 Module Integration

Each security module can be enabled/disabled independently:

use rustwall::{
    TorSecurityManager,
    AnonymityManager,
    ContentSecurityManager,
    OperationalManager
};

// Initialize security managers
let tor_security = TorSecurityManager::new()?;
let anonymity = AnonymityManager::new()?;
let content_security = ContentSecurityManager::new()?;
let operational = OperationalManager::new()?;
