Another methood is this:
system('stty -echo'); print "Enter Password: "; chomp($pw = <STDIN>); system('stty echo');

     This works but there are two caveats you should bear in mind:

    • If you're running the script as a priviledged process you might have just opened yourself to a local attack, if the user can modify their path and slip in a trojan 'stty' binary.
    • This fails utterly on Windows, amongst other systems.
