## 🚀 Getting Started
### 🛠️ Prerequisites
- [Rust](https://www.rust-lang.org/tools/install) (latest stable)
- [Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html)
### 📦 Installation
Clone the repository:
```bash
git clone https://github.com/austinsonger/rustwall.git
cd rustwall
```
Build and run:
```bash
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:
```bash
# 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:
```rust
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()?;
```
