KrypterPQ vs ArchiveX File Manager

Your private conversations deserve better than "end-to-end encrypted (trust us)." KrypterPQ 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 (RFC 9180) and send it any way you like. Only the person you choose can open it. Not us. Not Apple. Not anyone else. ENCRYPTED MESSAGES Write a message, encrypt it, and paste it into iMessage, WhatsApp, email, Signal, whatever. It stays unreadable wherever it travels, except to your recipient. KEYS THAT NEVER LEAVE YOUR IPHONE Every KrypterPQ key is created inside your iPhone's Secure Enclave, the same chip behind Face ID and Apple Pay. The private key can't be exported, copied or read, not even by KrypterPQ. POST-QUANTUM KEY SHARING Invite a contact with a link or QR code. Your public key travels back sealed with ML-KEM, the NIST post-quantum standard, so even a future quantum computer recording today's traffic learns nothing. Everyone sees keys only as SHA-256 fingerprints you can compare in person. CIPHERTEXT THAT SAYS NOTHING Every encrypted message and file starts with a header that looks like random bytes and is padded inside the encryption. Nobody can tell which algorithm was used, whether a password was added, or how big the original really is. PROVE WHO SENT IT Authenticated HPKE lets your recipient verify a message really came from you, not someone pretending to be you. No certificates. No authorities. Pure cryptography. ADD A PASSWORD Stack a shared password on top of the encryption, stretched with 5 million PBKDF2 rounds. Even with the right key, nobody reads it without the password. NOTHING STORED IN THE CLEAR Contacts, key names, dates, settings and the PIN are all sealed on your device with ML-KEM-1024 under the Secure Enclave, and behind your app PIN when it's on. A copy of the phone's storage reveals nothing. TRULY PRIVATE • No account required, ever. Not only not required: there is no way to create one • No network connections: KrypterPQ works fully offline • No data leaves your device unless you share it • No analytics, no tracking, no telemetry • App PIN with a panic PIN, tied to the Secure Enclave and Face ID • Decrypted text hidden from screenshots and screen recordings • Copied text expires from the clipboard after 30 seconds and never syncs to other devices • Privacy screen when you switch apps • No ads, no paywalls BACK UP YOUR CONTACTS Export your contacts in a password-encrypted backup (PBKDF2, 120 million iterations) and restore them anytime. Your keys stay in the Secure Enclave, as they should. STANDARDS-BASED Built on RFC 9180 HPKE, NIST P-256, AES-256-GCM, ML-KEM-768 and ML-KEM-1024, all from Apple's CryptoKit. No proprietary algorithms. No homemade crypto. KrypterPQ is encryption the way it should be: yours.
