Passwords

[John Chant]

Hi,

I'm new to Ruby ( one day), but not to programming (over 30 years) and I
would like some help.

I would like to be able to read a password without echoing the
characters typed. I've looked at getc but this echos the character (as a
number).

Something like the python getpass would be good.

The Ruby-Password library supports this. Check it out:
http://www.caliban.org/ruby/ruby-password.shtml

It's pretty simple:

Password.get( "Your prompt: " )

Thanks, that is simple, but where do I find Password?, what requires do I
need?

All of that information and more is available at the link I gave you.
It requires ruby-termios (which is available as a gem) and cracklib,
which should be available from your operating system's package
manager.

Needs the termios gem and UN*X.

an alternative suggestion is ...

def get_password
print "Password: "
`stty -echo`
@pass=STDIN.gets.chomp ensure `stty echo`
end

It's worth mentioning that of all the solutions recommended, Highline
is the only one that works cross-platform comfortably.

require "highline/import"

pass = ask("Enter your password: ") { |q| q.echo = false }
