NetRexx get password hidden? (masked by ***)

[Michael (maillists) Dag]

Is there a way in NetRexx to get the password hidden from the console? Like ask.hidden()

Found some Java myself but don’t like it and cannot change it right now as I am not a Java programmer… (and don’t want to either!)

 

Say ‘Password: ‘

 

When typing four characters show four ‘*’ for example ****

 

The one I found works with PasswordField and EraserThread but prints an ‘*’ at the prompt line and so when entering four characters you see actually five

which might lead you to believe you entered the wrong password…

 

[code_sample]

import java.io.*;

 

public class testpass {

    public static void main(final String[] args) {

        String password = PasswordField.readPassword("Enter password:\n\b");

        System.out.println("\nPassword entered was:" + password);

    }

}

 

 

class PasswordField {

 

   public static String readPassword (String prompt) {

      EraserThread et = new EraserThread(prompt);

      Thread mask = new Thread(et);

      mask.start();

 

      BufferedReader in = new BufferedReader(new InputStreamReader(System.in));

      String password = "";

 

      try {

          password = in.readLine();

      } catch (IOException ioe) {

          ioe.printStackTrace();

      }

      et.stopMasking();

      return password;

   }

}  

 

class EraserThread implements Runnable {

   private boolean stop;

   private int cnt = 1;

 

   public EraserThread(String prompt) {

       System.out.print(prompt);

   }

 

   public void run () {

      while (!stop){

         cnt = cnt + 1;

         if (cnt != 2 ) System.out.print("\010*");

         try {

            Thread.currentThread().sleep(1);

         } catch(InterruptedException ie) {

            ie.printStackTrace();

         }

      }

   }

 

   public void stopMasking() {

      this.stop = true;

   }

}

[/code_sample]

You could look at CHARVA

One of the biggest benefits of NetRexx is it's ability to leverage the "huge" Java API without needing to learn Java programming.

Here's a worked example of using java.io.Console to hide password inputs:

Options replace format comments java symbols
Import java.io

cons = System.console()
pw = Rexx
who = 'Michael'
count = 1
-- the Java way
pw = cons.readPassword('Enter password #%02d for %s: ', [Object Long(count), who])
say String.format('Password #%02d is: %s', [Object Long(count), pw])

-- the Rexx way
count = count + 1
say 'Enter password #' || count.right(2, '0') 'for' who': \0'
pw = cons.readPassword()
say 'Password #' || count.right(2, '0') 'is:' pw

Return

Just for kicks. A charva example.

import charva.awt.
import charvax.swing.

class IBM5250 public  extends charvax.swing.JFrame implements charva.awt.event.ActionListener

    properties private
        prompt = charvax.swing.JLabel
        passwd = charvax.swing.JPasswordField
        reveal = charvax.swing.JButton
        showit = charvax.swing.JLabel
        system = charvax.swing.JButton

    method IBM5250
        prompt = charvax.swing.JLabel()
        prompt.setText("Enter User Password:")
        passwd = charvax.swing.JPasswordField()
        passwd.setColumns(10)
        passwd.setText("")
        reveal = charvax.swing.JButton()
        reveal.setText("User Entered")
        reveal.addActionListener(this)
        showit = charvax.swing.JLabel()
        showit.setText("")
        system = charvax.swing.JButton()
        system.setText("Exit")
        system.setActionCommand("Exit");
        system.addActionListener(this)
        setDefaultCloseOperation(charvax.swing.JFrame.EXIT_ON_CLOSE)
        getContentPane().setLayout(charvax.swing.BoxLayout(getContentPane(), charvax.swing.BoxLayout.Y_AXIS))
        getContentPane().add(prompt)
        getContentPane().add(passwd)
        getContentPane().add(reveal)
        getContentPane().add(showit)
        getContentPane().add(system)
        pack()
        setVisible(1)

    method actionPerformed( evt=charva.awt.event.ActionEvent )
        actionCommand = evt.getActionCommand()
        if actionCommand.equals("Exit") then do
            exit
        end
        else do
            showit.setText(passwd.getPassword())
            passwd.setText("")
        end

    method main( args=String[] ) static
        x=IBM5250()
