--------------------------------------

             Summary: Enable white-space in parameters for external password command
                 Key: SECURITY-832
                 URL: https://issues.jboss.org/browse/SECURITY-832
             Project: PicketBox 
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: JBossSX
    Affects Versions: PicketBox_4_0_19.Final
            Reporter: Ivo Studensky
            Assignee: Peter Skopek
             Fix For: PicketBox_4_0_20.Final


The current implementation of the loading the external password by a command uses Runtime.exec() which denies to pass a parameter which contains a white-space to the command, see {{\{EXT\}}} in org.jboss.security.Util#loadPassword(String). 
It would be nice to provide a new implementation based on ProcessBuilder.

For example, various ssh-askpass implementations requires a parameter like 'Enter passphrase for ...'. Without the ability to directly pass such a parameter customers are pushed to create a "script in the middle" which makes their application unnecessarily complicated.
