A tiny library for reading passwords without displaying them on the terminal. It's similar to the C function getpass() or Python's getpass module.

Read a password without displaying it on the terminal:

let passwd = readpass::from_tty()?;

If you want to display a prompt, print it to stdout or stderr before reading:

use std::io::{self, Write};

write!(io::stderr(), "Please enter a password: ")?;
let passwd = readpass::from_tty()?;

Strings returned by readpass are wrapped in Zeroizing to ensure the password is zeroized from memory after it's Dropped.

The source code is released under the Apache 2.0 license.

This is a fork of rpassword by Conrad Kleinespel. The original library appears unmaintained, and rolls its own version of zeroize in rtoolbox. This crate aims to change that.
