This is a simple open-source notepad app which demonstrates the capability of the SQLCipher for Android encrypted database library. All notes created and stored by this app are saved fully secured using industry standard 256-bit AES encryption. They are never stored in an unencrypted state on the disk, only in memory.

SQLCipher is an SQLite extension that provides transparent 256-bit AES encryption of database files. To date, the core library has been open-sourced, sponsored and maintained by Zetetic LLC, and it was ported to Android in 2011 by the Guardian Project.

    On jellybean,I I could not place the file where I wanted to like on the SD card . The bigger and smaller didn't work when I hit smaller it became bigger and bigger and bigger.

    It crashes immediately upon opening. I'm running Android 4.4 on a nexus 5.
