Python Script That HIDES Any Message Inside a QR Code!

In this video, I show you how to use Python to encrypt any message you type… and hide it inside a QR code!
This QR code contains encrypted text that no one can read without the key — making it a fun and safe demonstration of real cryptography.
This technique is often used to store sensitive data securely inside QR codes in real-world applications.

Want a part 2 where I show you how to decrypt the hidden message?Comment “DECRYPT!” if you want it!

CODE:

from cryptography.fernet import Fernet
import qrcode

Ask user for a secret message
message = input("Enter the secret message you want to hide: ")

Generate encryption key
key = Fernet.generate_key()
cipher = Fernet(key)

Encrypt the message
encrypted = cipher.encrypt(message.encode())

Create QR code with encrypted text
img = qrcode.make(encrypted.decode())
img.save("secret_qr.png")

print("\n[+] QR Code Generated: secret_qr.png")
print("[+] Encryption Key (DO NOT share this):", key.decode())
print("\nScan the QR code to see the encrypted text!")
