🎯 Quick Start Guide

For Production

# 1. Get Let's Encrypt certificate (FREE)
sudo certbot certonly --standalone -d fleet.yourdomain.com

# 2. Configure security
cat > .agentic-qe/config/security.json <<EOF
{
  "tls": {
    "minVersion": "TLSv1.3",
    "requireValidCertificates": true,
    "rejectUnauthorized": true
  }
}
EOF

# 3. Set environment
export NODE_ENV=production

# 4. Initialize secure transport
npm start

For Development

# 1. Generate self-signed cert (DEVELOPMENT ONLY)
openssl req -x509 -newkey rsa:4096 -keyout dev-key.pem -out dev-cert.pem \
  -days 365 -nodes -subj "/CN=localhost"

# 2. Set environment
export NODE_ENV=development

# 3. Run with warnings
npm run dev

🔍 Code Examples

Secure Transport Initialization

import { createSecureQUICTransport } from './core/transport/SecureQUICTransport';

// Production-ready secure transport
const transport = await createSecureQUICTransport({
  host: 'fleet.yourdomain.com',
  port: 4433,

  // REQUIRED: CA-signed certificates
  security: {
    certPath: '/etc/letsencrypt/live/fleet.yourdomain.com/fullchain.pem',
    keyPath: '/etc/letsencrypt/live/fleet.yourdomain.com/privkey.pem',
    caPath: '/etc/letsencrypt/live/fleet.yourdomain.com/chain.pem',

    enableTLS: true,      // Always true
    verifyPeer: true,     // Always verify
  }
});

// Check security status
const status = transport.getSecurityStatus();
console.log('Security:', status);

Certificate Validation

import { CertificateValidator, loadSecurityConfig } from './core/security/CertificateValidator';

// Load security configuration
const config = loadSecurityConfig();

// Create validator
const validator = new CertificateValidator(
  config.validation,
  config.pinning,
  'production'
);

// Validate certificate paths
const result = validator.validateCertificatePaths(certPath, keyPath, caPath);

if (!result.valid) {
  throw new Error(`Certificate validation failed: ${result.errors.join(', ')}`);
}

// Load and validate certificate
const certInfo = validator.loadCertificate(certPath);
const validation = validator.validateCertificate(certInfo);

if (!validation.valid) {
  throw new Error(`Certificate invalid: ${validation.errors.join(', ')}`);
}

🛠️ Operations

Certificate Renewal (Let's Encrypt)

# Test renewal
sudo certbot renew --dry-run

# Setup automatic renewal (cron)
sudo crontab -e

# Add line (runs twice daily)
0 0,12 * * * certbot renew --quiet --post-hook "systemctl restart aqe-fleet"

Certificate Monitoring

# Check expiration
openssl x509 -enddate -noout -in cert.pem

# Monitor expiration (30 days warning)
days_until_expiry=$((($(date -d "$(openssl x509 -enddate -noout -in cert.pem | cut -d= -f2)" +%s) - $(date +%s)) / 86400))

if [ $days_until_expiry -lt 30 ]; then
  echo "WARNING: Certificate expires in $days_until_expiry days"
fi
