A monoalphabetic cipher uses a fixed substitution to encrypt the entire message. A monoalphabetic cipher utilising a Python dictionary and JSON objects. With the use of this dictionary, we can encrypt the letters and store the corresponding letters as values in JSON. The following program creates ...
