Consider a Playfair cipher that uses the password "WORKHARD". 1. Construct the matrix associated with this Playfair cipher. 2. Encrypt the plaintext message: "EVENINGS". Show your work step by step. Otherwise, your answer is wrong. 3. Decrypt the ciphertext message: "NYEECTYLYL". Show your work step by step. Otherwise, your answer is wrong.
