https://itunes.apple.com/us/app/text-locker/id706492969<p>This is my first iOS app. It only took me few hours to complete (and about an hour the next Sunday to fix 2 bugs).<p>My participation in some cryptography-related research this summer inspired me. After investigating options for ciphering text on iOS, I thought this App needs to exist.<p>The algorithm used is AES128+CBC mode followed by base64.
