HTTPS. How to encrypt keystorePass?

[Tim Ng]

hi all,
I have successfully configured https in JBoss by modifying {JBOSS-HOME}\server\default\deploy\jbossweb-tomcat50.sar\server.xml.

<Connector port="8443" address="${jboss.bind.address}"
maxThreads="100" minSpareThreads="5" maxSpareThreads="15"
scheme="https" secure="true" clientAuth="false"
keystoreFile="${jboss.server.home.dir}/conf/server.keystore"
keystorePass="changeit" sslProtocol = "TLS" />

My question is, is it possible for us to encrypt the value of keystorePass?If yes, how?

thanks.
