Question

I have a fixed password to decode images stored on the SD card. The purpose is not high class security, its simply to prevent users from using a folder with 1500 pictures for other purposes.

So I encrypted the pictures using 128RSA, put them on my server, download them to the SD card, and decrypt them on the fly to show them in the application.

I know its not perfect, but its better to have PictureA.jpg readable. And still better then simply renaming them to 1.bin – 999.bin.

BUT, currently there is one place in source which looks like passwort=”abc”. Is there a way to make it harder to decompile? I know, who wants to will be able to do it, but making it a little harder would be nice.

Thanks,
Chris

Use ProGuard.
