How it works: 1. Add a contact and complete a guided handshake to establish an encrypted session 2. Verify identity fingerprints through a trusted channel 3. Type your message -> tap "Encrypt & Copy" -> paste the ciphertext into any messenger 4. Receive ciphertext -> tap "Paste & Decrypt" -> read the plaintext Security: - End-to-end encryption powered by Signal Protocol (X3DH + Double Ratchet) - AES-256-CBC with HMAC-SHA256 for every message - Per-message forward secrecy: compromising one key cannot decrypt past or future messages - Out-of-order message decryption support - Identity fingerprint verification through a trusted channel - All keys are generated and stored locally on your device Features: - Works with any messaging platform, no need to switch apps - Guided handshake wizard with step-by-step instructions - Contact management with session status at a glance - One free contact; one-time Pro purchase for unlimited contacts - Supports English, Simplified Chinese, and Traditional Chinese - Available on iOS and macOS with cross-platform session compatibility - Dark mode support Your messages stay private, no matter which messenger you use.
