here's the solution given in the Perl FAQ:
How do I ask the user for a password?
(This question has nothing to do with the web. See a different
FAQ for that.)
There's an example of this in the "crypt" entry in the perlfunc
manpage). 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 the POSIX
manpage, and Chapter 7 of the Camel), 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
$password = ReadLine(0);
