Hi,

I need to hide a value in a mobile (Android OS) application. As far as I can see, encrypting the value is of no use as the key to the encryption mechanism must be available to the program and is thus available to an attacker reverse-engineering the code. So, it seems that the only "solution" is to hide the secret value in the application as well as possible, obviously not ideal. Any comments? Am I missing something? If not, what's the best way to hide the value?

Thanks for your ideas! Ewan
