Tasks Read the textbook about the details of Vigenére Cipher. Implement the algorithm by C or C++. Requirements You do this lab in a group of two students. Your program should have input and output as follows: csci>a.out --> Please input the key: receptive --> Please input the plain text: wearediscoveredsaveyourself --> The Cipher text is : nicvtwqngfzgvtwavzvcqyglmgj -->The original message is: wearediscoveredsaveyourself • You should test your program with several runs.

FCP takes a file, generates a random 2048 bit key and encrypts the file with a RC4 stream Cipher. The encrypted file is written to a new file along with the decryption stub and key. When the output file is executed it decrypts and executes the encrypted file. It s written in Delphi 6, enjoy the source code.

Playfair Cipher 1.not even the large number of keys in a monoalphabetic Cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair
