## ⚙️ Requirements

- Python: Version 3.x
- Dependencies: `cryptography` library

You can install the required library using pip:

bash
apt install python3-cryptography

---

🚀 Installation

1. Clone the repository:

   git clone https://github.com/CYBER-MRINAL/SEC-File.git
   cd SEC-File

2. Install dependencies:

   python3 setup.py

---

🛠️ Usage

1. Run the script:

   python3 SEC-File.py

2. Follow the prompts:

   • Enter e to encrypt files or d to decrypt files.
   • Provide the full path to the folder containing the files you want to encrypt or decrypt.
   • Enter a password for encryption or decryption.
   • Optionally, choose to backup original files before encryption.

🔍 How It Works

Encryption Process:

• Generates a random salt and derives a key from the provided password using PBKDF2.
• Encrypts all files in the specified folder, appending a .enc extension to the encrypted files.
• Securely deletes the original files after encryption (unless backup is chosen).

Decryption Process:

• Reads the salt from salt.bin and derives the key using the same password.
• Decrypts files with the .enc extension and restores the original filenames.
• Securely deletes the encrypted files after decryption.

📊 Logging

All operations are logged in encryption.log for auditing purposes. You can check this file to see the history of encryption and decryption operations.

🔒 Security Considerations

• Strong Passwords: Always use a strong password for encryption.
• Backup Important Files: Ensure that you have backups of important files before using this tool, especially if you choose to delete original files.
