The task should be done in a group of max 3 In the program explained during the lab the client sends only 1 message to server ‘hello from tcp client’ server responds with the uppercase message. Update the program / make a simple chat program so that Client can send/receive multiple messages to server. A special exit message is used to disconnect ‘Exit’. Each time client sends a message, server responds with a confirmation of receiving it and its length (use the screenshots in the presentation as a reference)
Implement the first round of AES ( Advanced Encryption Standard ) in python. Given a message with 128 bits, two subkeys subkey0 and subkey1, your program should be able to perform one AddKey before Round 1 and the corresponding operations (SubBytes, ShiftRows, Mix-Columns, and AddKey) in Round 1, and output the result of the encryption after Round 1.

write a program in python as implementation of decryption of affine cipher. output should be:encrypted message is:....decrypted message is:..... plaint text: cryptologya coefficient: 3b coefficient: 1
Write a Python program in a Linux/UNIX script called myprogram.py. Write a Python program that continuously (i.e., in an infinite loop) asks the user for a number m. At each iteration of the loop, check in parallel whether m is greater than 10, greater than 20, and greater than 30. Make sure that the three comparisons may be performed in parallel (i.e., so that the three outputs can theoretically be printed in any order). Use the smallest number of processes. Make sure you don’t create zombie processes. Use the code below as a template. Use this template: from os import wait,waitpid,fork # write your code here while (True): #make sure to indent this and the next lines m=float(input('Give me a number: ')) # your code here
Write a JavaFX program to read a username and password from the user and store it in a databse in a encrypted manner during the signup. Validate given user by reading his credentials by decrypting it from the database. (use shift methods for encryption and decryption ex: A-C, B-D, C-E).
Making a Python program that reads an IP address and determines whether it is syntactically correct or not. Assuming the format of the IP address is ###.###.###.### where 999 represents a number between 0 and 255. Use the `split function to access the values in the input IP address.
Tracing the steps methodology, to write a java program, where the server side receive a TCP connection from client side, and then the client upload on the server the following files using FTP: 1- Image file named “ Myimage.jpg” if the client upload <image file>.2- Text file named “Mytext.txt” if the client upload <text file>.

Develop a single program using a python programming language that:a. Encrypts and decrypts a message using the Cesar’s Cipher. The user encryptingthe message is prompted to enter a message and then a key that indicates the displacement.The user decrypting the message is prompted to enter the encrypted message and the key.b. Decrypts and displays all (26) possible solutions
Write an application in java that encrypts and decrypts on Counter mode using: Aphine chiper modulo 256, Hills chiper modulo 256 and S-DES (Simplifies DES). Testing data for S-DES using Counter mode start from: 0000 0000, with text in binary form: 0000 0001 0000 0010 0000 0100 and key: 01111 11101 which will give the result: 0011 1000 0100 1111 0011 0010. Decryption should work.
