1) A written application which makes encryption and decryption by Caesar encryption, application first asks the user if he wants encryption or Decryption, then write the relevant text and display the result. Should allow users to write in capital letters and small letters and numbers? (3 points)
2) The written application that implements extended Euclid algorithm (recurrent method)? (1 point)
3) The written application that implements the encryption permutation. At first application prompts the user if wants encryption or Dekriptim, then given the length of permutation and permutations, relevant text and display the result? (3 points)
4) The written application that makes the attack on encrypted text via permutation encryption, knowing that the length of permutation not exceed 6? (3 points)
Who can help me to write this aplications, can anyone do it for me
