Whisper vs Secret Text

Want to send some secrets to somebody? Whisper can help you! By encrypting with a specific key, Whisper can turn any text into Emojis. You can then send these Emojis any way you want. Without the corresponding key, your secrets can never be compromised. Whisper supports to create two kinds of keys: Random Secure Key and Passphrase Derived Key. Both kinds of keys can be shared with QR code. Whisper uses a hybrid 256-bit encryption algorithm, which is theoretically difficult to break. To learn more, just try it now!

Secret Text is free to download and use for contact setup and handshake. It is a secure text translator, not a chat app. Encryption and decryption require an active 3-day free trial or Secret Text monthly/yearly auto-renewable subscription. It encrypts your plaintext into ciphertext that you can copy and paste through any messaging app (iMessage, WhatsApp, Telegram, WeChat, etc.), and decrypts ciphertext back into plaintext on the other end. How it works: 1. Add a contact and complete a guided handshake to establish an encrypted session 2. Start the official 3-day free trial or subscribe to unlock encryption/decryption 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 - Monthly and yearly auto-renewable subscriptions with a 3-day free trial - 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.
