Question

Write a code using Python to encrypt messages with one of the historical (or modern) ciphers or to hack (decrypt) the cipher. The following ciphers are required:
• Caesar
• One of transposition ciphers
• Vigenere
• Frequency analysis (Counting number of letters in a cipher)
• One-time pad
• Public key cipher (RSA)

Notes:
• You can write a code for encrypting the plaintext messages or decrypting ciphers.
• You should submit (upload) 2 files: One for explaining the problem and the code and second file for the code itself.
• Students who see themselves weak in programming, they can utilize the ready codes.
