Watch for signals in terminal

terminal.go

package main

import (
	"fmt"
	"os"
	"os/signal"
	"syscall"
	"golang.org/x/crypto/ssh/terminal"
)

func main() {

	// check for ctrl-c signal
	signalChan := make(chan os.Signal)
	signal.Notify(signalChan, os.Interrupt)
	go func() {
		<-signalChan
		os.Exit(1)
	}()

	// read password
	p, err := terminal.ReadPassword(syscall.Stdin)
	if err != nil {
		panic(err)
	}

	// stop watching signals
	signal.Stop(signalChan)

	// print password
	fmt.Println(string(p))
}

Hey, thanks for this.
I gave it a try, unfortunately it still left my terminal in a bad state after issuing a Crtl+C while the prompt is open.
I was able to fix it by adding/amending the following:

// Get the state of the terminal before running the password prompt
originalTerminalState, err := terminal.GetState(int(syscall.Stdin))
if err != nil {
        os.Stderr.WriteString("Failed to get terminal state")
	os.Exit(1)
}

go func() {
        <-signalChan
        // Reset the terminal to the original state if a the user issues an interrupt
	terminal.Restore(int(syscall.Stdin), originalTerminalState)
	os.Exit(1)
}()
