Caesar Cipher Program

This is a simple Python project I created while learning Python through freeCodeCamp. The program uses the Caesar Cipher technique to encrypt and decrypt text based on a shift value provided by the user.

How It Works

• Text: The message the user wants to encrypt or decrypt.
• Shift Value: The number of positions each letter in the alphabet is shifted.

For example, with a shift value of 3:

• A becomes D
• B becomes E
• HELLO becomes KHOOR

The program supports:

• Text encryption
• Text decryption
• Uppercase and lowercase letters
• Input validation for shift values

Purpose

This project was built as a practice exercise while learning Python fundamentals such as:

• Functions
• Loops
• Conditionals
• String manipulation
• User input handling

Although it’s a small side project, it helped me better understand how basic encryption algorithms work and improved my problem-solving skills in Python.
