Jdbc connection to Oracle

I'm connecting neo4j to Oracle via a jdbc string in the neo4j configuration file. The configuration file contains the jdbc call with the password in clear text. How can I secure the jdbc connection?

Example:
apoc.jdbc.oracle_url.url=jdbc:oracle:thin:username/password@databasename

Hi, do you have the suite of this question please ?
I have de same concern now.
Adavance thanks
