message. To decrypt the ciphertext, we compute the following: C = ciphertext m = message (given) e = Euler number φ n = p*q C = 4 ^ 7 mod 21 = 16384 mod 21 = 4 The rule for Message Encryption Step three: Message Decryption Rule: M = c^d mod n To get the value of D: D= e^-1 mod Euler D = 7^-1 mod 12
