🔒 File Encryption & Decryption Tool

👉 AES Encryption for secure file protection
👉 RSA Key Encryption to securely store the AES key
👉 User-Friendly GUI with an intuitive interface
👉 Dark & Light Mode Toggle
👉 Progress Bar for Encryption/Decryption
👉 Drag & Drop Label (Future Feature)

git clone https://github.com/yourusername/file-encryptor.git
cd file-encryptor

Make sure you have Python 3.7+ installed. Then, install the required libraries:

pip install cryptography tk

Before encrypting files, generate your RSA key pair:

python generate_keys.py

This will create:

• private_key.pem → Used for decryption (Keep it secure)
• public_key.pem → Used for encryption

python gui_encryptor.py

A window will open with options to encrypt and decrypt files.

1. Click "Encrypt File".
2. Select any file (e.g., .txt, .pdf, .jpg, .mp4).
3. The tool will:
   • Encrypt the selected file and save it as filename.enc.
   • Encrypt the AES key and save it as aes_key.enc.
4. ✅ Success Message:
   "File Encrypted Successfully!"

1. Click "Decrypt File".
2. Select the encrypted file (filename.enc).
3. The tool will:
   • Decrypt the AES key using private_key.pem.
   • Restore the file to its original state.
4. ✅ Success Message:
   "File Decrypted Successfully!"
