Secure QR Steganography and Encryption Tool
Project description
QR Stego Secure
This tool securely hides encrypted messages inside QR codes using AES encryption and LSB steganography. The visible QR contains a decoy message, while the real message is hidden inside the image.
🚀 Features
- 🔐 AES-256-CBC encryption using passphrase
- 🖼️ LSB-based steganography to embed encrypted data in QR code images
- 🪄 Automatically generated decoy messages for QR readability
- ✅ Safe offline encryption/decryption
- 🧹 Optionally wipe hidden data after decoding
🔧 Installation
pip install .
Install from PyPI:
pip install qr-stego-secure
Usage
Encode a secret message:
qr-stego --encode --message "Secret123" --passphrase "myp@ss" --image "secret_qr.png"
Decode a secret message:
qr-stego --decode --passphrase "myp@ss" --image "secret_qr.png"
