Feature description

Encrypt items(pics/vids/folders) when the user chooses to lock items. Request a master password(or pattern/pin/biometrics, if there's a way to generate a immutable password from those)

Why do you want this feature?

It would provide more privacy and security and give the user the option to easily encrypt medias.
