In this video, we explain Public–Private Key Cryptography (Asymmetric Cryptography) in a simple and beginner-friendly way, along with the RSA algorithm explained step by step using a numerical example.
You will learn:
✔️ What is cryptography and why it is needed
✔️ Symmetric vs Asymmetric Cryptography
✔️ Public key and private key concept
✔️ Real-life analogy of public key cryptography
✔️ RSA algorithm key generation steps
✔️ Encryption and decryption using RSA
✔️ Numerical example for better understanding
✔️ Real-world applications of public key cryptography
This video is especially useful for:
📌 Computer Science & IT students
📌 Cybersecurity and Network Security learners
📌 Exam preparation (University exams, GATE, competitive exams)
📌 Beginners learning cryptography
Public key cryptography is widely used in HTTPS, SSL/TLS, digital signatures, secure email, online banking, and cryptocurrency systems.
