KryptEY is a secure, privacy‑focused Android keyboard that implements the Signal Protocol (X3DH + Double Ratchet) directly in the keyboard layer. It enables end-to-end encrypted messaging within any app—without relying on external servers—ensuring that key exchanges and message encryption happen locally, maintaining Signal-level security across platforms.
Features
- Implements full Signal Protocol (X3DH & Double Ratchet)
- Independent from messenger apps, no integration needed
- Uses X25519, SHA‑256/512, AES‑256‑CBC for encryption
- Generates public key fingerprints via SHA‑512
- No server‑side routing or dependency
- Open‑source and actively maintained
