8.9: How do I ask the user for a password?

(This question has nothing to do with the web. See a different FAQ for

There's an example of this in "crypt" in perlfunc). First, you put the
terminal into "no echo" mode, then just read the password normally. You
may do this with an old-style "ioctl()" function, POSIX terminal control
(see POSIX or its documentation the Camel Book), or a call to the stty
program, with varying degrees of portability.

You can also do this for most systems using the "Term::ReadKey" module
from CPAN, which is easier to use and in theory more portable.

use Term::ReadKey;

$password = ReadLine(0);

so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
