hibernate - Inserting Encrypted data in postgres

Question

In our database, credit card number is encrypted, to store encrypted data in postgresql database we are doing following way.

\set pubkey '''' `sed -e "s/'/''/g"  -e 's/\\n/\\r\\n/g'  -e  's/\\/\\\\/g' < /home/vinit/fnpub.key` '''' 

 \set pvtkey '''' `sed -e "s/'/''/g"  -e 's/\\n/\\r\\n/g'  -e  's/\\/\\\\/g' < /home/vinit/fnpvt.key` '''' 

select pgp_pub_decrypt(number, dearmor(:pvtkey),'testypassword' ) from payment_detail limit 2; 

Application is using hibernate, how to insert data with encryption and read decrypted data using hibernate?

Thanks!!
