Repository: crypto-tools-repo
Purpose: Educational repository demonstrating Caesar Cipher encryption & decryption with Python.

• Simple Caesar cipher implementation (encryptdecypt.py).
• Interactive CLI for encrypting and decrypting text.
• No third-party libraries required.

• encryptdecypt.py — main script for Caesar cipher encryption and decryption.
• README.md — project overview and usage instructions.
• requirements.txt — dependencies list.
• LICENSE — MIT license.
• .gitignore — standard Python ignores.
• SECURITY.md — security notes and risks.
• INSTALL.md — installation and usage guide.

1. Install Python 3.8+
2. Clone this repository or download the ZIP
3. Run the script:

   python encryptdecypt.py

4. Enter your text and choose Encrypt or Decrypt.

Do you want to (E)ncrypt or (D)ecrypt? E
Enter the text: HELLO
Enter the key (integer): 3
Encrypted text: KHOOR

This project is for educational purposes only. Caesar cipher is not secure and should not be used for real-world data protection.

✨ If you'd like, I can help extend this repo to include:

• Vigenère cipher, AES, or RSA demos
• GUI interface (Tkinter or PyQt)
• Unit tests and GitHub Actions CI
