Reading a password from std::cin

Question

I need to read a password from standard input and wanted std::cin not to echo the characters typed by the user...

How can I disable the echo from std::c

Answer 1

There's nothing in the standard for this.

In unix, you could write some magic bytes depending on the terminal type.

Use getpasswd if it's available.

You can system() /usr/bin/stty -echo to disable echo, and /usr/bin/stty echo to enable it (again, on unix).

This guy explains how to do it without using "stty"; I didn't try it myself.
