Because your privacy is what we want to protect, Encryptor+ is not collecting any data. It only needs permissions for the file system to encrypt and decrypt your files. See the privacy policies for more information's.
1. Encrypt and decrypt multiple files or folders at once.
2. Encrypt and decrypt files while the app is not running.
3. Work when the device is sleeping.
Your key is generated out of 4 different components.
1. Component is your password, expanded by the PBKDF2 algorithm.
2. Component is a randomly generated number of characters called salt, that is added to your password. This will make your password random and unable to find in a dictionary, no matter what a weak password you
typed in. With this salt, your files are secure against dictionary attacks.
3. Component is a randomly generated number of bytes, that is added to your files content, to make sure that every time you encrypt a file with the same key, it looks differently. This component will protect you against rainbow table attacks.
4. Component is another randomly generated number of characters, that is also added to your password, with the difference that it is not saved anywhere. Because it is not saved, the app has to guess it, therefore
taking more time at decryption.(about 2x) The good point is, that a potential hacker also needs to guess this number to decrypt a file, making him effectively 2 times slower when using a burteforce attack.
You can turn this feature on or off with the pepper setting.
Overall, Encryptor+ is a very secure and easy to use solution to make your private files save.

Feedback is very welcome.
This app wont collect any data. Basically it can't because it does not require the internet permission, so it can't even send data. The only permissions it requires are the permissions to the file system, needed for the encryption and the decryption, and the wakelock permission, needed to encrypt while the screen is turned off.
