Creating a Reverse Cipher in Python Cryptography

For this Cipher blog, we build on a simple plaintext to cipher function creating a function named reverseCipher that accepts one parameter: plaintext and get plaintext as a human readable input from user by using input method . We can then call our function and pass the plaintext into it and print out the return ciphertext. Our method modifies the plaintext so that the ciphertext is the complete reverse: 

 

 

#!/usr/bin/python
import time

def reverseCipher(plaintext):
    ciphertext = ''
    i = len(plaintext) - 1
    while i >=0:
         ciphertext = ciphertext + plaintext[i]
         i = i - 1
    return ciphertext
    



plaintext = input('Enter your plaintext for encoding : ')
ciphertext = reverseCipher(plaintext)
print(ciphertext)

 

This code should produce the following result:
