A free app for Android, by Nicolas BERNE.
Caesar Cryptogram is a simple and intuitive application to help you decipher the messages that you receive from your friends and family, as well as to help you to discover who is trying to tamper with your smartphone.
The application will be more useful if you receive an encrypted message and you do not know the key.
How to use it:
You have to turn on the device encryption and then you have to select the right key (the one you know). If you do not know the key, the application will be more useful because it will help you to discover who is trying to tamper with your smartphone.
