Write a program that implements an elementary bit stream cipher. An elementary level bit stream cipher is an encryption algorithm that encrypts 1 byte of plain text at a time. This one uses a given 4-bit bit pattern as the key. The size of the encrypted message that we want to be able to send has a maximum length of 200 characters. You must: 1. prompt the user to input the clear text to be encrypted. You must use printf()...

1) Echo the input: First, you should make sure you can write a program and have it compile and run, take input and give output. So to start you should just echo the input. This means you should prompt the user for the plaintext, read it in and then print it back out, with a message such as "this is the plaintext you entered:". [4 points, for writing a working program, echoing the input and submitting the program on the...

C Program In this assignment you'll write a program that encrypts the alphabetic letters in a file using the Vigenère cipher. Your program will take two command line parameters containing the names of the file storing the encryption key and the file to be encrypted. The program must generate output to the console (terminal) screen as specified below. Command Line Parameters Your program must compile and run from the command line. The program executable must be named “vigenere” (all lower...

MATH 1030 – Application Assignment 3 Cryptography Due: Thursday, June 4, 2020 at 11:59pm Atlantic time (submit through Brightspace) You must show your work for full marks. The goal of this assignment is to use our knowledge of linear algebra to do cryptography. We will encrypt a plaintext using a cipher where the resulting ciphertext should not be legible unless...

**DO IT AS PYTHON PLEASE**
The Trifid Cipher General Problem Description The Trifid cipher (not to be confused with the creatures from the classic science-fiction film "The Day of the Triffids") is an algorithm that enciphers a plaintext message by encoding each letter as a three-digit number and then breaking up and rearranging the digits from each letter's encoded form. For this assignment, you will create a set of Python functions that can encode messages using this cipher (these functions...

Programming Assignment #6 Help Me Find The Secret Message Description: This assignment will require that you read in an encrypted message from a file, decode the message, and then output the message to a file. The encryption method being used on the file is called a shift cipher (Info Here). I will provide you with a sample encrypted message, the offset, and the decrypted message for testing. For this project I will provide you main.cpp, ShiftCipher.h, and ShiftCipher.cpp....
