defyance has asked for the wisdom of the Perl Monks concerning the following question:

I wrote a small prog using perl and Net::Telnet, that logs into a box and runs a small command of the users choice (i.e. ping, w, finger). To keep security risks down and so it can be used by miltiple persons, it reads <STDIN> for the users username and pass. But I can't seem to conceal the password. Any ideas? I'm pretty new to perl, But I think I understand the basics.
