Chapter 8, Problem 11RQ
Program Plan Intro
Symmetric and asymmetric encryption:
The encryption technique uses the same secret key for sender and receiver to encrypt and decrypt the message is known as symmetric encryption.
The sender and receiver uses different keys for encryption and decryption is known as asymmetric encryption. It is otherwise known as public key cryptography.
