Introduction:

This Python program implements the Caesar Cipher method for encryption and decryption. The Caesar Cipher is a type of substitution cipher in which each letter in the plaintext is ‘shifted’ a certain number of places down the alphabet.

Features:

• Encrypt a message using the Caesar Cipher method.
• Decrypt a message encrypted using the Caesar Cipher method.
• User-friendly: Prompts user for inputs and displays outputs.

Requirements:

• Python 3.x

Installation:

1. Clone the repository to your local machine.
2. Navigate to the directory containing the program.
3. Run the program using Python 3.

Usage

1. Run the program.
2. Choose whether you want to encrypt or decrypt by entering ‘E’ or ‘D’.
3. If you choose to encrypt:
   • Enter the plaintext message you want to encrypt.
   • Enter the shift key (an integer).
   • The program will display the encrypted message.
4. If you choose to decrypt:
   • Enter the encrypted message you want to decrypt.
   • Enter the shift key (an integer).
   • The program will display the decrypted message.
