Add in functionality for homophonic cipher.
Each letter of the alphabet is replaced by any number of other letters

While using the monoalphabetic substitution cipher, the order of the display of the key and the ciphertext is confused. Also, it has problems itself because I try each for the ciphertext and another o…

### Description
The Affine cipher is a monoalphabetic substitution cipher in which each letter in the alphabet is mapped to a numeric equivalent. This number is then encrypted using a straightforward…

### Detailed description
The Playfair cipher is a classical encryption technique that uses a 5x5 grid to encrypt pairs of letters (digraphs) in a message. This method helps obscure the frequency an…

1.1 Develop a simple menu based (gui or text based) substitution cipher tool (such as a
Caesar cipher). The cipher tool should provide both encryption function and decryption
function. The parameters…
