Keystore password for Jetty 7.0 SSL configuration
I think you just want to overwrite the keystore in etc/keystore with your new one. Then, update the Jetty conf as in Step 4. You will need to obfuscate your keystore password using the org.mortbay.jetty.security.Password
class.
The default password for the keystore that is shipped with jetty is storepwd
. But I would highly recommend you follow the steps listed in the How to configure SSL and create your own keystore.
