A Python implementation of the Caesar Cipher algorithm that performs encryption and decryption using a user-defined shift key. Developed as part of my Cyber Security Internship at SkillCraft Technology.

This project is a Python implementation of the Caesar Cipher, one of the earliest and simplest encryption techniques in classical cryptography.

It allows users to:

Encrypt plaintext messages

Decrypt ciphertext messages

Use a custom shift key (1–26)

Preserve spaces and special characters
