Definition

The cryptographic protocol that encrypts data in transit between a client and server — the technology behind HTTPS that prevents eavesdropping and tampering of network traffic.

البروتوكول التشفيري الذي يُشفّر البيانات أثناء النقل بين العميل والخادم — التكنولوجيا التي تقف وراء HTTPS والتي تمنع التنصت والعبث بحركة مرور الشبكة.

Why It Matters

Without TLS, passwords, API keys, and personal data travel in plaintext across the network and can be intercepted by anyone on the same Wi-Fi. Modern browsers flag HTTP sites as insecure.

بدون TLS، تنتقل كلمات المرور ومفاتيح API والمعلومات الشخصية كنص صريح عبر الشبكة ويمكن لأي شخص على نفس الشبكة اعتراضها.

Full Definition

TLS (Transport Layer Security) is the successor to SSL. The TLS handshake: (1) Client sends supported cipher suites and TLS version. (2) Server presents its TLS certificate (public key, signed by a Certificate Authority). (3) Client verifies the certificate chain. (4) They negotiate a symmetric session key. (5) All data is encrypted with that key. TLS 1.3 (current) is faster and more secure than TLS 1.2. HTTPS = HTTP over TLS. Vercel automatically provisions TLS certificates (via Let's Encrypt) for all custom domains.

TLS هو الخلف لـ SSL. يُشفّر قناة الاتصال بين طرفين. مصافحة TLS: العميل يرسل مجموعات التشفير المدعومة، الخادم يُقدّم شهادة TLS، يتفاوضان على مفتاح جلسة متماثل، وجميع البيانات تُشفَّر. HTTPS = HTTP عبر TLS.

Example Usage

“Without TLS, passwords, API keys, and personal data travel in plaintext across the network and can be intercepted by anyone on the same Wi-Fi. Modern browsers flag HTTP sites as insecure.”

“بدون TLS، تنتقل كلمات المرور ومفاتيح API والمعلومات الشخصية كنص صريح عبر الشبكة ويمكن لأي شخص على نفس الشبكة اعتراضها.”

AI Builder Tips

Avoid these mistakes when using TLS/SSL:

Confusing TLS encryption with end-to-end encryption → TLS encrypts between client and server, but the server decrypts and sees plaintext. E2EE means the server never decrypts.

Using TLS 1.0 or 1.1 → Both are deprecated with known vulnerabilities. Enforce TLS 1.2 minimum, prefer 1.3.

Setting `NODE_TLS_REJECT_UNAUTHORIZED=0` in production → This disables certificate validation entirely, making MITM trivial. Never use it outside localhost.
