2. Use the rail fence cipher to encrypt the statement "meet me after the toga party" 3. Using mathematical means and a key  "OUTSIDE", find the cipher text using vigenere cipher given the plaintext to be "THESUNISSHINING". The definition for vigenere cipher is given below: P = Z26 C = Z26 K = Z26 e((x1, x2, …., xn)) = ((X1+K1) mod 26, (X2+K2) mod 26, … , (Xn+Kn) mod 26)
