Your private conversations deserve better than "end-to-end encrypted (trust us)." Krypter puts real encryption in your hands — no middlemen, no servers, no fine print. ENCRYPT ANYTHING Photos, documents, voice memos, videos — encrypt any file with HPKE (Hybrid Public Key Encryption) and share it safely. Only the person you choose can open it. Not us. Not Apple. Not anyone else. ENCRYPTED MESSAGES Send private text messages that only your recipient can read. Copy, paste, send through any channel — iMessage, WhatsApp, email, Signal, whatever. The message stays locked no matter where it travels. YOUR KEYS, YOUR RULES Krypter generates encryption keys inside your iPhone's Secure Enclave — the same chip that protects Face ID and Apple Pay. Your keys physically cannot leave the device. Not even Krypter can see them. SIMPLE FOR YOU, IMPOSSIBLE FOR THEM Add friends as trusted contacts. Encrypt files and messages with one tap. No technical knowledge needed — Krypter handles the hard math while you handle your life. PROVE WHO SENT IT HPKE authenticated encryption lets the recipient verify it really came from you — not someone pretending to be you. No certificates needed. No authorities. Pure cryptography. FUTURE-PROOF Quantum computers are coming. Krypter includes XWing post-quantum hybrid encryption (ML-KEM-768 + X25519) so your secrets stay secret — today and decades from now. ADD A PASSWORD Stack a pre-shared key on top of HPKE encryption for double protection. Even if someone has your public key, they still can't read your files without the password. FOUR ENCRYPTION CURVES • P-256 Secure Enclave — hardware-locked, non-extractable • P-521 — maximum-strength NIST curve • X25519 + ChaCha20-Poly1305 — fast, modern, battle-tested • XWing ML-KEM-768 — post-quantum hybrid, future-proof TRULY PRIVATE • No account required — ever • Not joking about the above point: not only not required, but not even able to create any sort of account • No network connections made by the app — fully offline by design • No data leaves your device • No analytics, no tracking, no telemetry • PIN lock with duress PIN support • Clipboard auto-clears after 30 seconds • Privacy screen when you switch apps • No ads, no paywalls BACKUP YOUR KEYS Export your software keys with military-grade password protection (PBKDF2, 120 million iterations). Restore anytime. Hardware keys stay sealed in your Secure Enclave — as it should be. STANDARDS-BASED Built on RFC 9180 HPKE, NIST P-256/P-521, X25519, AES-256-GCM, ChaCha20-Poly1305, and ML-KEM-768. No proprietary algorithms. No vendor lock-in. Your encrypted files use documented, open formats. Krypter is encryption the way it should be — yours.
