Encrypting texts is similar to enclosing a text into a safe. To enclose the text in the safe, a secret key is used for enclosing the Text into the safe. If you want to encrypt a text, first enter a secret key . The key can be any string. Then enter the text to be encrypted in the input field in the input area. If you do not enter a secret key, "Secure Text" will use an internal secrect key. The encrypted text is now displayed in the output area. To transfer the encrypted text to another app, tap the copy icon, that copies the encrypted text and it can be pasted into any other app. If you want to decrypt a text, you will need the secret key with which the text was encrypted. Make sure that the decode icon is displayed in the lower right corner of the input area and in the output area. If not, tap the icon to toggle in to the decrypt mode.

LockWhisper is a private, offline-first security vault for iPhone, iPad, and Mac. It keeps sensitive personal data encrypted on your device without cloud accounts, analytics, tracking, or LockWhisper servers handling your vault contents. ONE PRIVATE PLACE Store passwords, 2FA codes, PGP keys, encrypted notes, journals, plans, files, photos, videos, voice recordings, contacts, cards, identity records, travel documents, vehicle records, saved links, emergency information, habits, and private tasks. LockWhisper also includes a secure browser, secure clipboard, QR and scanner tools, photo metadata cleaning, encrypted search, favorites, import and export tools, and device-to-device sync. PRIVATE BY DESIGN Every supported module is built around local encryption and device-controlled storage. Your vault stays on your device unless you choose to export it or sync supported data directly to another trusted device. A DASHBOARD YOU CONTROL Use daily privacy tips, Quick Actions, Security Snapshot, backup health, favorites, and quick modules to reach what matters. Choose layout presets, change visual density, group modules, resize widgets, and decide which cards appear. REAL AND DECOY VAULTS LockWhisper includes an optional fake password system. Your real password opens your private vault. A separate fake password opens a decoy vault with separate data for plausible deniability. SECURITY TOOLS YOU CAN USE Security Center summarizes password health, authenticator coverage, encryption-key rotation, backup readiness, recovery status, and other actionable findings. Optional auto-destruct, recovery tools, key backup, jailbreak and debug checks, and YubiKey-assisted workflows provide additional protection. PRIVATE DEVICE SYNC Sync supported data directly between trusted devices over encrypted peer-to-peer connections. No LockWhisper account and no central cloud database for your vault contents.
