Storing photos on external sdcard by default

Is there a method to store photos/videos on the external sdcard by default? I've got a rooted i9295 running a recent Cyanogenmod nightly.
Possibly there is there a camera application that allows setting the default storage location for photos. Something I'm missing here? TIA.

How does the WhatsApp's messages storing encryption work?

Hello everybody,

This is my first message.

What I would like to know is how WhatsApp encrypts the databases. I mean, does it use simple encryption or asymmetric (public-key) encryption? In case it uses simple cyphering, it would be possible to create a cyphered database from a SQLite file by using the key file located in the "hidden" WhatsApp directory but, in case it uses public-key cyphering, I don't know where the public key is located nor how both keys are generated.

If you root the device and the encryption is simple or symmetric, it would be easy to generate a "false" database but, in case the encryption is asymmetric, it wouldn't be so easier and it would be necessary to generate a public-private key pair.

Does anybody know how does it work?

Thank you very much!!!
