Python Program to Create Xor Encryption Assignment Solution

Instructions

Objective

Write a python homework program to create xor encryption.

Requirements and Specifications

XOR Encryption in Python

What You Need

Your Kali VM, that should have Python 3 installed. And ability to read the following guideline of XOR operation.

Purpose

In this Project you will build a tool using python to encrypt and decrypt a text message using XOR method.

• User will input a Word and to encrypt
• User will input a Key
• Your program will take these inputs and use the Python ord function to encrypt the word
• Your output needs to have the following
• Your encrypted text
• Your plain text
• Binary value of the plain text
• Binary value of the Key
• Binary value of the XOR (encrypted) output
• Hex value of the text plain text
• Hex value of the text encrypted text
