How to use encrypted password in camel cxf ws-security properties file

Issue

We have ws-security policy defined in our WSDL using AsymmetricBinding Assertion and our camel cxf consumer endpoint is configured as:

 <cxf:cxfEndpoint id="personEndpoint"
                   address="http://localhost:8092/PersonService/"
                   serviceClass="org.apache.servicemix.samples.wsdl_first.Person"
                   wsdlURL="wsdl/person.wsdl">
        <cxf:inInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"/>
        </cxf:inInterceptors>
        <cxf:outInterceptors>
            <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"/>
        </cxf:outInterceptors>
        <cxf:properties>
            <entry key="dataFormat" value="POJO"/>
            <entry key="ws-security.callback-handler">
                <ref component-id="serviceKeystorePasswordCallback"/>
            </entry>
            <entry key="ws-security.signature.properties" value="etc/jboss_keystore.properties"/>
            <entry key="ws-security.encryption.properties" value="etc/jboss_truststore.properties"/>
        </cxf:properties>
      </cxf:cxfEndpoint>

One of the properties files, for instance "etc/jboss_keystore.properties", looks like:

org.apache.ws.security.crypto.provider=org.apache.ws.security.components.crypto.Merlin
org.apache.ws.security.crypto.merlin.keystore.type=jks
org.apache.ws.security.crypto.merlin.keystore.password=secret
org.apache.ws.security.crypto.merlin.keystore.alias=jboss
org.apache.ws.security.crypto.merlin.keystore.file=keys/jboss.keystore.jks

However, the property "org.apache.ws.security.crypto.merlin.keystore.password" here is a clear text.

Is there a way to use encrypted password for the "org.apache.ws.security.crypto.merlin.keystore.password" property in those properties file?
