Encrypt and exchange messages via QR codes using a permanently offline device.

Webfreeglobal

QR Crypt is a free, open-source tool for encrypting and exchanging messages using a device kept permanently offline — the message is encrypted and shown as a QR code, scanned by an everyday online phone, and sent through any regular messenger, with keys never touching an internet-connected device. It's built for people who need to exchange sensitive messages with the strongest practical protection against a compromised online device.
