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.

    Haven't been able to get it to open. It says it has closed unexpectedly before it has a chance to open.

    I am still giving 3 stars although it has not worked once for me. I'm doing so because the cause is noble. Once it works on my my phone I will give 5 stars.
