RSA Cryptosystem Concepts and Challenges

The video tutorial introduces the RSA cryptosystem, explaining its encryption and decryption processes. The teacher uses a simplified example to demonstrate how messages are encrypted and decrypted using modular arithmetic. The lesson concludes with a homework assignment to explore the method further.
