JDBC connect String Password Encryption

i would like to know how to use encryp password in JDBC jdbcplugin.conf file

i need to encrypt the below jdbc_password, since i cant use as clear text. please let me know if any other info required

input {
jdbc {
jdbc_driver_library => "/opt/ojdbc14.jar"
jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
jdbc_connection_string => "jdbc:oracle:thin:@host:port:db"
jdbc_user => "DB_user"
jdbc_password => "password"
statement => "SELECT count(*) from tab"

Have you been able to solve this?

Looks like in the last release (via GitHub), they've added a new property "jdbc_password_filepath"
