So you say it is encrypted eh?

As I said the database is encrypted(in the case of linux systems)

Motivation?

I am taking a random database file called test.db which uses sqlite3 as the database engine. Doing a hexdump over it

$ hexdump -C test.db | head -n 20

I can see the whole darn schema table!

With encryption

Now on the other end, let's do the same for the database file tnote uses to store your notes
