KrypterApp

3.0 is our biggest privacy update yet. ◆ Post-quantum key sharing Invite a contact with a link or QR code. Your key travels back sealed with ML-KEM, so nobody ever sees your raw public key, only its fingerprint. ◆ Ciphertext that says nothing Every message and file now starts with a header that looks like random bytes, and is padded inside the encryption. Nothing gives away the algorithm, whether a password was used, or the real size. ◆ One key type: Secure Enclave Every key is created inside the chip and can't be copied or exported, not even by Krypter. ◆ Nothing stored in the clear Every contact, key name, date, setting and the PIN itself is sealed on your device under the Secure Enclave with ML-KEM-1024, and behind your app PIN when it's on. A copy of the phone's storage reveals nothing. ◆ Private by default Decrypted text is hidden from screenshots and screen recordings. Quick Open now starts off. ◆ Stronger passwords and PIN Password messages take far longer to brute-force, and the app PIN's Secure Enclave key now also asks for Face ID or your passcode. ◆ Fresh look Contacts and keys appear as fingerprints, the new-key screen explains what you're getting, and the QR code is restyled with a dark-mode theme. Heads-up: a fresh start • 3.0 starts clean. Keys, contacts, PIN and settings from earlier versions are deleted on first launch. Back up your contacts in your current version before updating, and restore them after. • Messages and files encrypted with earlier versions can't be opened in this one. • Create a new key and send fresh invites. Ask your contacts to update too: earlier versions can't read what this version sends.
