Testrunner.sh using encrypted properties

Hi,

We would like to be able to just encrypt the settings file or a properties file for use at the command line.

Is that possible?

Also, can you describe a scenario when the following two arguments would be required for execution of the testrunner? 

-t <arg> Sets the soapui-settings.xml file to use
-v <arg> Sets password for soapui-settings.xml file

 How do you require a password for the soapui-settings.xml?

Thanks.
