Private files and messages, encrypted on your iPhone. OneCryption is an offline encryption tool for people who prefer to exchange secret keys in person. It does not operate a message-delivery network: you choose how to send the encrypted result. HOW IT WORKS 1. Meet your contact and confirm their identity. 2. Generate shared secret key material and transfer it directly between nearby devices. 3. Write a message or select content, encrypt it locally, and share the encrypted result through a channel you choose. 4. The recipient decrypts it with the matching shared key. YOUR KEYS, YOUR CONTROL - Encrypt and decrypt text, photos, videos, audio and files. - Manage contacts and shared keys on your device. - See how much key material remains and exchange a fresh key when needed. - Use local encryption without a OneCryption messaging account. OneCryption uses a one-time-pad workflow. Key material must remain secret and must never be reused. Protect the devices and the key exchange. The channel you use to deliver encrypted content has its own privacy and metadata implications; encryption does not make a compromised device safe. FREE AND PREMIUM Text encryption is available for free. Some media and file features require Premium. Purchase options and current prices are shown in the app. If you choose a subscription, it renews automatically unless you cancel it in your App Store account settings.
