Download CryptODroid (256 bit AES) apk 1.0.2 free for Android smartphone
Apk file size: 2.3 MB
CryptODroid can protect any file using a strong 256 bit encryption algorithm. A key is generated at random every time the encryption process runs, so encrypting the same file twice results in two unique outputs.
This is just the initial release. The UI is very basic and there are probably some bugs to work out that I haven't come across yet. But hey its free.
A desktop compatible java version of this app will be available at https://github.com/admanne/crypter
I will do my best to keep both apps in sync.
You alone are responsible for retaining and managing your keys. If you lose the key to one of your encrypted files, you will NEVER be able to decrypt it (at least not until 256bit AES is cracked). In addition, you may want to move your generated keys to a secure location. Keeping them in the same folder where the encrypted files land is about as secure as saving your passwords in a text file... be smart.
