Extracted text: s Used for encryption. SMRER TL CJ LOJJC 2. The following ciphertext message was encrypted using Vigenére Cipher cipher with keyword JEDI. MS. RZ MS QWC. XKMAI LA WS WZH. Determine the plaintext message. 3. The following ciphertext message was encrypted using the RSA algorithm and public key (2021,97). 1259 0854 1647 1139 Determine the plaintext mnessage. 4. Using the EIGamal eryptosystem, create and encrypt a message for me. The plaintext message must be a recognizable word or phrase and at least eight alphabetic characters long. Divide the numerical plaintext into two digit blocks. Use a unique ephemeral key (j) to encrypt each block. My publie key is (89. 14, 8). CO 5.
