[Feature] Encrypt local files

Is there an existing request for feature?

What feature would you like?

Encrypt local files (downloaded photos, conversations and etc) that are stored on the device, so they can be decrypted and viewed only through the app (where you can setup a password). Not everybody encrypts their whole devices, so this enhancement is very important (specially if Session adds a goddamn ability to setup password, which is not related to phone's pin code — even my friends now it!)

How about GPG?
