The first time you send an encrypted message keys are exchanged automatically. Thereafter it tells you if the second party's identity changes from the first message. If you're thinking "But MitM!!!" then don't. The main weakness of this is actually the plausibility of losing your phone, and hence encryption keys. Unless perhaps they are stored on Google/WhisperSystems' servers. If not it would open you up to this weakness: "Hey, ignore the security warning for this text - I got a new phone so the keys changed. Remind me again what our secret terrorist plan is?" |
