I assume that you're trying to protect against a backup of the
database falling into the wrong hands? If so, your connectivity
layer should be doing the work. Get the vendor to support what you
need or replace the layer with something which has better support
(or that you can support yourselves).
Any solution which includes what's necessary for decryption in the
dump will not really be much of a solution.
If you're trying to protect against something else, please clarify.
