🔐 _Encryption__Decryption_project_cs
Caesar Cipher Encryption & Decryption System
A Python-based implementation of the classical Caesar Cipher algorithm that allows users to encrypt and decrypt messages using a custom shift value.
🚀 Features
- Encrypt text messages
- Decrypt encrypted messages
- Supports uppercase & lowercase letters
- Preserves spaces and special characters
- Input validation for shift value
🧠 Algorithm Used Caesar Cipher (Substitution Cipher)
Encryption Formula: C = (P + K) mod 26
Decryption Formula: P = (C - K) mod 26
Where:
P = Plaintext
C = Ciphertext
K = Shift value
🛠 Technologies Used
- Python 3
- VS Code
- Git & GitHub
