QRCipher

Full description (≤ 4000 characters)

QRCipher lets you easily encrypt any text into a secure QR code and decrypt it later with your password. Perfect for sharing sensitive data, notes, codes, or keys while keeping them fully private.

🔐 Main features:

Secure encryption: AES-256-GCM with PBKDF2-HMAC-SHA256 key derivation

Local & private: All encryption and decryption happen entirely on your device

Password-protected: Only users with the correct password can decrypt the QR code

Easy generation: Type your text, choose a password, and instantly get a scannable QR code

Fast scanning: Scan encrypted QR codes and reveal the content securely

Smart detection: Automatically distinguishes encrypted codes (prefix QC1:)

Offline support: Works even without an internet connection

🛡️ How it works:

Enter a text and a password, then tap “Generate QR”.

Share or save the generated QR code (without sharing the password).

On another device, open QRCipher, enter the password, and scan the QR code to decrypt the message.
