Crypted password - Mailing list pgsql-jdbc

Hi,
Is there any easy way to send to PostGre a user database crypted
password readed from jdbc.properties ?

jdbc.driverClassName=org.postgresql.Driver
jdbc.url=jdbc:postgresql://localhost:5432/my_db
jdbc.username=dev
jdbc.password=#postgre crypted password#
jdbc.defaultAutoCommit=false

thanks
