Problem 1a.

Using the original plaintext below in bold quotes (e.g. use only alphabet characters, a-z), write a program (in Matlab or python) to encrypt plaintext into ciphertext using the Caesar cipher.

If he had anything confidential to say, he wrote it in cipher, that is, by so changing the order of the letters of the alphabet, that not a word could be made out. Getting started:

Problem 2b. Using the ciphertext you generated from Problem 1a, write a program to decrypt ciphertext into plaintext using the Playfair cipher. Your program is to print or graph results

Problem 3a.Using the original plaintext from Problem 1a, write a program to encrypt plaintext into cipher using the Hill cipher.

Problem 3b. Using the ciphertext you generated from Problem 1a, write a program to decrypt ciphertext into plaintext using the Hill cipher. Your program is to print or graph results
