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. Cipher text is logical shift left by 2 positions
• Logical shift left by 1 position: Rightmost bit becomes ‘0’.
