Sqlite doesn't come with encryption built in, however you can enable encryption in sqlite by either purchasing the official paid extension here for 2000ドル. Or you can take a chance on one of the free alternative like this one. I have no idea how well the free versions will work, but I imagine the paid one is quite robust and up to date.

You will also need to build a custom qt sql driver by following the instructions here. And finally you must run this sql immediately after opening the database
