These routinely bypass end-to-end encryption through keyloggers, screen capture and compromised keys. Smartphones are part of complex ecosystems with dozens of hardware and software components and remain vulnerable despite vendor and political efforts.\n\nWe introduce a simple, offline, airgapped device to counter such threats.\n\nCheckout www.qryptr.com and github.com/gappuser/qryptr\n\nShow-and-tell of qryptr, the completely open-source secure messaging device.\nCheckout
