Using python write a program to encrypt plaintext into cipher using the Playfair cipher. Getting started: 1. Use the 5 by 5 matrix with keyword monarchy. 2. Iterate over each character of the plain text: 1. If the character is alphabet: 1. Follow the four rules on page 39 of the course text to encrypt two plaintext letters at a time. 2. Calculate the position/index of the character in the 0-25 range. 3. Find the character at the new position. 4. Replace the current letter by this new character. 2. Else, If the character is not alphabet, ignore the character, and move to the next position in the plaintext. with no change. 3. Your program is to print or graph results.
