$1.$ Choose a Cryptographic Algorithm

Select a cryptographic algorithm of your choice, such as ChaCha$20,$ Diffie$-$Hellman

Key Exchange, Secure Hash Algorithm $3($SHA$)$ or BlowFish. Research and

understand the working principles and security features of the algorithm.

$2.$ Programming Implementation

Implement the program using a suitable programming language $($e$.$g$.,$ Python, Java,

C$++,$ etc.$).$ Ensure that the program utilizes the selected cryptographic algorithm for

encryption and decryption.

$3.$ Testing and Demonstration

Test the program by simulating the networking scenario. Demonstrate how the

program successfully encrypts and decrypts the data, ensuring secure

communication between the client and server.
