How SSL/TLS Certificates Work? 🔒🌐

🛑 Don’t Trust a Site Without HTTPS!

SSL/TLS ensures your connection to websites is secure and private — no eavesdropping, tampering, or impersonation.

🔍 How does it work?

1️⃣ Your browser requests a secure connection to a website (e.g., https://).
2️⃣ The web server sends its SSL certificate with its public key.
3️⃣ Your browser checks the certificate’s authenticity using the Certificate Authority (CA).
4️⃣ A shared secret is generated and encrypted using the public key.
5️⃣ The server decrypts it with its private key.
6️⃣ A secure session is now established using that shared key.
7️⃣ You browse safely — all data exchanged is encrypted.

🔑 SSL/TLS is the backbone of internet trust.

Never share sensitive info on sites without it!
