Smoke and Mirrors The app sells a false sense of security. A true "one-time pad" requires a pre-shared secret sent over separate secure channel. Afterwards, an eavesdropper cannot decrypt the traffic, so simple XOR is optimal, as each bit of conversation consumes one bit of key. In contrast, using this app with a public wifi hotspot, the key material and subsequent conversation are exposed. (Even cellular monitoring captures all traffic.) More secure than this app are good public key systems with strong and long keys. OpenWhisper Systems protocol is end-to-end encrypted with a ratchet blocking playback of intercepted messages.
