- Practice using multiplicative ciphers to encode and decode a message: 1. Find quote that you like. Make sure that the total number of characters is at least 50 and no more than 100. 2. Then pick an acceptable number (not every number between 1 and 26 is acceptable) that is between 3 and 25 as your multiplicative key. Share this key. 3. Create a table of correspondence of 26 alphabets in plaintext and the ciphertext. (4) Use the table of correspondence to encode the quote you found in Part (1). Post the encrypted message in groups of three letters in the discussion forum. For example, here is another quote from John Dewey Education is not preparation for life; education is life itself. We will use multiplicative key 17. The table of correspondence between plaintext and ciphertext is as follows. (image attached Thus the encrypted message is GPS YQB WUD WKD UBL TGL QTQ BWU DXU TVW XGG PSY QBW UDW KVW XGW BKG VX (5) Pick an encrypted message from your classmate and try to decrypt…1.
