WebThe introduction of the monoalphabetic cipher can be found from the Week 1 lecture notes. Specifically, this assignment task is expected to do the following: Design and develop a Python program with encryption and decryption functions for monoalphabetic cipher. A sample Python program caesar for caesar cipher is provided for reference. WebMonoalphabetic and Polyalphabetic Cipher. Monoalphabetic cipher is a substitution cipher in which for a given key, the cipher alphabet for each plain alphabet is fixed throughout the encryption process. For example, if ‘A’ is encrypted as ‘D’, for any number of occurrence in that plaintext, ‘A’ will always get encrypted to ‘D’.
