This is not real security. Encrypting the data in the application only works
if the application is running on a computer you control. If the "customer"
can get their own copy of the client and run it on a computer they control
then they can steal or borrow the applications credentials.

You want to either run the app on a computer you control or have a contract
with the customers prohibiting them from connecting to the database other than
by using the app.
