lease answer all parts of the question   2. For the given plaintext: “thechildrenlearntocipherandsing” and cipher mentioned below, find the ciphertext: a. Key = 5 for Rail Fence cipher b. Key = 4 (number of rows) for Transposition cipher c. Key = 3 for Rail Fence cipher d. Cipher text is circular shift RIGHT by 2 positions • For example: circular shift right by 1 position: leftmost bit in the ciphertext is the same as rightmost bit in the plaintext e.
