There are patches for very simple encryption scheme on Google. To use them,
basically patch & recompile.
You can buy support for sqlite, that includes encryption, here:

That's insecure. If you want to do such things, you could as well just add a
few bytes to the beginning of sqlite file - the user won't be able to read
database with sqlite command-line tool - and such method has almost the same
level of security like the one you proposed.
