🔐 AES File Encryption Tool

A secure file encryption and decryption tool built using Python that uses Advanced Encryption Standard (AES) to protect sensitive data.

---

🚀 Features

• 🔐 Encrypt files using AES encryption
• 🔓 Decrypt encrypted files securely
• 🗂️ Supports any file type (text, images, PDFs, etc.)
• 🔑 Password-based encryption
• ⚡ Fast and lightweight CLI-based tool

---

🧠 How It Works

1. User provides a file and password
2. The password is converted into a secure encryption key
3. File is encrypted using AES algorithm
4. Encrypted file can only be decrypted using the correct password
