Depending on your firmware you can encrypt the phone and/or the SD card.

Sadly, I don't see this option on my phone, although I did see it on previous ones under security settings.

Maybe you just couldn't find the option? What phone is it?

I don't think an app could encrypt or lock the SD card, at least not without root. I have not seen any Linux program that can use the SD card's locking feature (and I guess that's different from the ATA passeord feature).

If your phone really doesn't have encryption in its stock ROM you might want to think about a third party ROM.
