      "localizedDescription": "Kryptos encrypts your messages right where you write them, so you never have to jump between apps.\n\nThe Kryptos keyboard turns any text field into an encrypted one: type in WhatsApp, Telegram, iMessage or SMS, tap once, and the message leaves as code. A message you receive is decrypted on the spot, in the keyboard or with one tap in the app.\n\niPhone and Android talk to each other freely, so it does not matter what your friend carries.\n\nNo accounts, no servers, no setup. The app has no networking code at all and your keys never leave the device.\n\nAlso inside: PGP mode, a password mode for one-off messages, and steganography that hides a message inside an ordinary photo or a harmless run of words.\n\nEncryption is the Signal Protocol, using Signal's own libsignal library: a fresh key for every message, with post-quantum protection on each one, not just on the handshake (PQXDH plus the SPQR ratchet). Keys live in the iOS Keychain, the app can be locked with Face ID, and the clipboard clears itself.\n\nSource code: https://github.com/swisslite/Kryptos",
