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 (

• 256 bit AES encryption format (AES Crypt version 2)
• File encryption and decryption
• Secure erase of original files after encryption or decryption
• Internal file browser for selecting, deleting and renaming files, setting output directory, setting key file
• Send/share functionality (Google Drive, SkyDrive, Box, Dropbox, Gmail, Bluetooth etc.)
• Encrypt your files before putting them in the cloud storage (Google Drive, SkyDrive, Box, Dropbox etc.)
• Password can be in Unicode (you can select password like "密碼 パスワード пароль كلمة السر" )
• Password can be up to 100 characters (minimum 6 and recommended at least 12 characters or more)
• Encrypted files have .aes extension which clients on other operating systems recognize
• Select where files will go after encryption/decryption (ie. sync folders)
• Key file support (file which contains password up to 1024 characters in length for encryption/decryption)

Notice: Speed of encryption or decryption depends a lot on speed of internal memory/SD card!

    The maximum file size is 5mb, who wants to encrypt a file less than that. This app can't encrypt anything bigger so it is useless

    I encrypted a text file in NoteEverything Pro. I was still able to open it afterward, even though it shows AES on the end of the file name. Where did I go wrong?

    Might be operator error but I cannot seem to set the output directory for decryption in Settings. Touching the option to do so does nothing. BUT the app works perfectly in conjunction with AES Crypt which is the reason I need this helpful app. Galaxy S 2 Android 4.1.2.

    Why don't you just update this to remove limits? You're not making money by keeping the full version on your hard drive. Instead, add a Paypal donation page in the app itself and people will donate. (Just keep it as a link so it doesn't require any permissions. It will open in the browser). Good luck. Will try it now.

    You say Google doesn't support selling in our country. Why? I would pay for a version with bigger file size and multiple file selection. Just need a fully functional version. You have adds for some revenue. Is it a government issue? I need a reliable aes encryption tool with no back doors or government ties. Can you do please?

    If AES encryption is good enough for U.S. government to use, it should be good enough for my cell phone.
