Encrypts plain text using AES256

This app does not claim any permissions, so you can trust that it cannot send any of your private data to anyone.

Can You Trust it? Messages produces by this app is secure and can be confidently send over a network, for example. It uses AES in CBC mode with PKCS5 padding for encryption, and uses PBKDF2 with HMAC, SHA1 and a random Salt in order to derive a secure key from the entered password. This is a very powerful encryption. Also it encrypts its settings before storing them on the device.

However, the app itself may not be very secure, and probably vulnerable to some attacks. Although it is secure enough to stand attacks from non-expert crackers, e.g. normal users, it should not be used for serious data encryption.

Important Note: If you are updating from version 3.X to 4.X, please clean your data after upgrade. (Settings -> App -> SimpleTextCrypt -> Clear Data). Or else, the app won't work.
