Furious Chargers – AES File Encryption with 2FA

A Cybersecurity project that provides AES-256 file encryption and decryption with 2-Factor Authentication (2FA) using Time-based One-Time Passwords (TOTP) generated by authenticator apps like Google Authenticator.

---

Project Overview

Furious Chargers is a secure file authentication system where:

• Files are encrypted using AES-256

• Decryption requires:

  • Correct password
  • Valid OTP (changes every 30 seconds)

• OTP is generated using Authenticator Apps (TOTP standard)

This ensures confidentiality, integrity, and strong access control.

🚀 Features

• AES-256 File Encryption
• Secure File Decryption
• Password-Based Protection
• 2-Factor Authentication (TOTP)
• OTP changes every 30 seconds
• QR Code support for Authenticator Apps
• Simple and clean Flask Web Interface

How 2-Factor Authentication Works (TOTP)

1. During encryption/decryption, a secret key is generated

2. The secret is shown as a QR Code

3. User scans the QR using:

   • Google Authenticator
   • Microsoft Authenticator
   • Any TOTP-compatible app

4. The app generates a 6-digit OTP

5. OTP changes automatically every 30 seconds

6. Only a valid OTP + correct password allows decryption

This follows the RFC 6238 – TOTP Standard
