EN-Register is an incredibly robust, secure, and fully-featured self-service registration portal built specifically for Enhance web control panel. Designed from the ground up for maximum security, beautiful UI/UX, and GDPR compliance, it requires zero database setup (100% flat-file logic) and handles customer organization creation and subscription assignments flawlessly through the native Enhance (orchd) REST API.

✨ Enterprise-Grade Features

🛡️ Unrivaled Security & Privacy

• Enhance Native Invite Workflow: Seamlessly delegates password creation to native Enhance invitation emails upon account creation, eliminating client-side password handling and storage.
• Advanced Rate-Limiting (Token Bucket): Fully protects the Enhance API against brute-force and DDoS spam attacks using a highly efficient, session-independent Token Bucket algorithm based on cryptographically hashed IPs.
• No Database Required: Works strictly with local flat files (JSON/PHP). All sensitive data and log files (audit.log.php, used_codes.php, demo_accounts.json) are completely locked down and unreadable from the web.
• Strict Content Security Policy (CSP): Ships with hardened HTTP response headers (X-Frame-Options: DENY, X-Content-Type-Options: nosniff, Referrer-Policy, Permissions-Policy, and CSP) out of the box.

🌐 Internationalization & UX

• 30+ Supported Languages: Comes fully translated into 31 languages (English, German, French, Italian, Czech, Polish, Turkish, Russian, Chinese, Korean, Arabic, Hebrew, Hindi, and 18 more).
• Responsive Dark/Light Mode: Automatically adjusts its premium UI to system preferences with an interactive manual toggle.
• Frictionless Onboarding: Ultra-fast registration requiring only organization name and email, maximizing user conversion.
• Fail-open DNS MX Checks: Automatically verifies the existence of mail servers (MX records) for the email domains entered during registration with built-in 60-second caching.

🤖 Ultimate Anti-Bot Protection

Native, zero-friction integration for:

• hCaptcha
• reCAPTCHA (Google v2)
• Cloudflare Turnstile
• ALTCHA (Self-hosted Proof-of-Work, 100% GDPR compliant)
• MTCaptcha

🎟️ Exclusive Access & Demo Modes

• Invite-Only Mode: Lock registration so only users with pre-generated, single-use or multi-use invitation codes can register.
• Automated Demo Mode: Temporarily track created customer organizations and automatically purge them after a configurable time window (e.g. 2 hours) via a background CLI cronjob (cron_cleanup.php).

🚀 Installation & Setup

1. Upload & Extract: Upload the files to your PHP 8.x web server directory.
2. Configure: Rename config-blank.php to config.php (or edit config.php directly) and specify:
   • EN_API_URL – Your Enhance panel API URL (e.g., https://panel.yourdomain.com/api)
   • EN_BEARER_TOKEN – Your Enhance Access Token (generated in Enhance panel → Settings → Access Tokens)
   • EN_ORG_ID – Your reseller organization UUID
   • EN_PLAN_ID – Default hosting plan ID for new subscribers
   • Captcha keys (CAPTCHA_PROVIDER and site/secret keys)
3. Set Random Secrets: Generate and set unique random strings for security:
   • LOG_IP_SALT: For GDPR-compliant IP pseudonymization (openssl rand -hex 16)
   • ALTCHA_HMAC_KEY: If using ALTCHA proof-of-work (openssl rand -hex 32)
4. Done: The system automatically creates and protects the necessary data/ and logs/ folders upon the first registration attempt.

⏱️ Demo Mode & Cron Setup (Optional)

If DEMO_MODE is enabled in config.php, customer organizations created during testing or live demos will be scheduled for deletion after DEMO_LIFETIME_HOURS.

To enable automatic cleanup, add the following cronjob to your server's crontab:

# Edit crontab
crontab -e

# Add cron entry (runs every 30 minutes)
*/30 * * * * php /path/to/your/webroot/cron_cleanup.php >> /dev/null 2>&1
