Caesar Cipher in python with Source code

Caesar Cipher in python with Source code


Caesar Cipher is message encryption and decryption based project. Caesar cipher is one of the widely used encryption techniques. It is written in python programming language.  

Caesar cipher is using python version 3.9.5. Python is a general-purpose high-level programming. Caesar cipher is an intermediate-level project. This project will let you to encrypt and decrypt your messages. It is a useful project. Caesar cipher techniques is mostly used for military purpose while sending a secret message. When you encrypt your message using Caesar you even do not understand your message unless you decrypt it.

The project has a command line interface. When you execute the project you must choose options for encrypt or decrypt. For encryption enter encrypt. It will ask you to enter your message, shift number and your encrypted text is ready. Similarly, if you want to decode you must enter the encrypted message and shift number, you will get your decoded message. See the screenshots below.

Building the project

This Caesar cipher project is built using python programming. You can encrypt and decrypt your message easily without getting error in this project. For encryption we are using 26 alphabets to generate a random message. We are using def functions, if else for selecting the options for decode and encode.

We further use for loops to generate the encrypted text. While loop is used here to repeat the question whether the user want to encode or decode. If the answer is no the project ends. We are using ASCII art to improve our user interface. You can use this project to enhance your skill. Download the project and get experienced by yourself.
