Hi:
Assuming using SEE, do is there the ability to decide what I/O operations are
to be performed encrypted or with the plain (as is) content?
I'm planning an application with only selected data encripted (in each row of
certain tables, there is a flag showing the encrypted/plain state).

I am no programmer, and I only know a small number of very basic SQLite

Occasionally I bump into some proprietary software that's using SQLite behind
the curtain and I wonder if they have bought a license. I know SQLite is public
domain and it is not required to buy a license while using it for commercial
