📌 In this video you will learn:
✔ What is Public Key and Private Key?
✔ What is Encryption & Decryption?
✔ Symmetric Encryption Explained (AES)
✔ Asymmetric Encryption Explained (RSA)
✔ Why RSA is slow but secure?
✔ Why AES is fast but key sharing is risky?
✔ What is Hybrid Encryption?
✔ How WhatsApp End to End Encryption works?
✔ Why ECC is used instead of RSA in mobile apps?

🔐 Encryption Explained Simply:
Symmetric encryption uses the same key for encryption and decryption (AES).
Asymmetric encryption uses two different keys – Public Key & Private Key (RSA / ECC).

🚀 Hybrid Encryption:
First RSA/ECC is used to securely share the AES key.
Then AES is used for fast and secure communication.
This is how modern internet communication works.

📱 Real-world example:
WhatsApp End to End Encryption uses Hybrid Encryption (ECC + AES) to keep your messages secure from hackers.
