This video is designed for beginners and focuses on understanding the core idea of cryptography, without using heavy mathematics or complex algorithms.
In this video, you will learn:
What cryptography means in practice
Why cryptography is needed in digital systems
How information is protected using encryption and decryption
Where cryptography is used in everyday applications
This is the first video in a structured cryptography series that starts from basics and gradually moves toward more advanced topics.
If you want to understand cryptography conceptually — not just memorize definitions — this video is for you.
