Get Password in Console with Ruby

In Ruby 2.3, they introduced a getpass method on the IO::console class. There are no dependencies since it part of the standard library, but it's only available in versions higher than 2.3. For older versions, we'll look at an alternative method. The getpass method is similar to gets except it will not echo back what you are typing in. This is good for getting a password without printint it to the screen when you type it in. This will demonstrate how to use the method. See the official documentation for IO::console#getpass for more details. We will also look using $stdin.noecho() to wrap Kernel.gets to get a password.

One-line HTTP servers
