This application is used for encrypting and decrypting files with 256 bit AES algorithm. You can use it to encrypt files before putting them on online locations (cloud storage, Google Drive, Skydrive, Box, Dropbox, Gmail, etc.) or to store encrypted sensitive files on your Android phone so that they are unreadable to those who don't know your password.

This application is accompanied by clients for different operating systems like Windows, Mac OS X, Linux and operating systems that can run Java. Source code of AES Crypt algorithm and client software is available at AES Crypt (
