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()...

Implement the RC4 stream cipher in C++. User should be able to enter any key that is 5 bytes to 32 bytes long. Be sure to discard the first 3072 bytes of the pseudo random numbers. THE KEY OR THE INPUT TEXT MUST NOT BE HARD CODED IN THE PROGRAM. program should be tested by a plain text You should write TWO PROGRAMS: encryption and decryption. The encryption program should input the plaintext file and output a cipher text in...

Implement the RC4 stream cipher in C++. User should be able to enter any key that is 5 bytes to 32 bytes long. Be sure to discard the first 3072 bytes of the pseudo random numbers. THE KEY OR THE INPUT TEXT MUST NOT BE CODED IN THE PROGRAM. Test your program with the following plain text: In cryptography, RC4 (Rivest Cipher 4 also known as ARC4 or ARCFOUR meaning Alleged RC4) is a stream cipher. While remarkable for its...

8.16 Ch 8, Part 1: XOR Cipher Write this program using Eclipse. Comment and style the code according to CS 200 Style Guide. Submit the source code files (.java) below. Make sure your source files are encoded in UTF-8. Some strange compiler errors are due to the text encoding not being correct. This program will implement a simple XOR cipher on an integer array, where the data to be encoded is XOR'd with a key. This idea is often used...

Please write a function that will do the following Decryption of a message encrypted with a substitution cipher given cipher text only without any key Please provide comments on each line of code outlining what that line is doing. Note: Only the Function is to be written, all user inputs i.e the text to be decrypted will be entered earlier in the program. Code must be written in C and be able to be compiled using GCC If any...

Decrypting the APCO cipher without the key.
Decryption without the key is obviously a much more difficult
process. Indeed, the purpose of encryption is to make it as
difficult as possible for anyone who does not know the key to read
the plain text. We will be using an unsophisticated password
cracking technique called a brute force attack. A brute
force attack on the APCO cipher works by trying every possible four
digit key (from 0000 to 9999) and keeping...
