Getpass for GO.

Leverages the good work from the people over at OpenSSL.org via cgo to provide 
a simple, and cross platform getpass implementation. The API provided essentially
wraps the UI_UTIL_read_pw_string function call in <openssl/ui.h>.

// Prompt the user for their password.
func GetPass()(pw string, e os.Error)

// Prompt the user for their password, and get them to confirm it. 
func GetPassConfirm()(pw string, e os.Error)

// Full customization of the call. Arugments essentially map to UI_UTIL_read_pw_string
func GetPassWithOptions(prompt string, confirm, max int)(pw string, e os.Error)

Example Usage: 

package main

import (
    "os"
    "fmt"
    "github.com/gcmurphy/getpass"
)

func main(){
    fmt.Println("Use default prompt:")
    pw,e := getpass.GetPass()
    if e != nil {
        fmt.Println("ERROR: ", e.String())
        os.Exit(1)
    }
    fmt.Println("Password = ", pw)
}
