Hibernate version: 3.2

Hi

I would like to encrypt some database columns that stores sensitive information. Now I know that there is a Jasypt library that I can use for this but I need a solution that works in the database. Oracle has a database package called DBMS_CRYPTO that you can use to encrypt and decrypt values. How can I create a mapping that will automatically use this package to encrypt when he inserts or deletes a row, or decrypts when you query the data. Is this possible?
