One-time pads are a form of mathematically uncrackable encryption, based a large, single-use symmetrical encryption key shared between only two people. If the encrypted messages are intercepted, they are completely impossible to decrypt without access to the recipient's copy of the one-time pad key! OneTimePad allows you to create shared one-time pad keys with a friend using the app, and use the keys to encrypt (or decrypt) messages, which you can send however you like. For more details, screenshots, and guides, please check out the application's webpage. OneTimePad is, of course, Available on the App Store. Unfortunately, since OneTimePad contains advanced encryption, and has not yet been authorised for export from the U.S.A. it is only available in the U.S. App Store at this time.
