qrypt0

qrypt0 is a system to exchange messages encrypted by a computer which is permanently offline. The ciphertext is transferred to an online computer by encoding it into a QR code and scanning it off the screen. Encryption can no longer be circumvented by exploits using vulnerabilities in operating systems.
