getpasswd functionality in Go?

Question

Situation:

I want to get a password entry from the stdin console - without echoing what the user types. Is there something com

You can get the behavior you want with the Read method from the os.File object (or the os.Stdin variable). The following sample program will read a line of text (terminated with by pressing the return key) but won't echo it until the fmt.Printf call.

package main

import "fmt"
import "os"

func main() {
  var input []byte = make( []byte, 100 );
  os.Stdin.Read( input );
  fmt.Printf( "%s", input );
}

If you want more advanced behavior, you're probably going to have to use the Go C-wrapper utilities and create some wrappers for low-level api calls.
