Token Generation + +- Tokens are 32-byte cryptographically secure random values +- Prefix: `apx_` for easy identification +- Stored as SHA-256 hash (one-way) + +### 3. Token Comparison + +- Uses constant-time comparison to prevent timing attacks +- Validates hash, not plain token + +### 4. HTTPS/TLS + +⚠️ **Always use HTTPS in production!** + +```bash +# Set up reverse proxy with Nginx/Caddy +# Or use Railway/Fly.io for automatic HTTPS +``` + +### 5.
