	var salt string = "Gm8uSwfozUKXXatEJLpBB1cNq0F0AR1U7LRaqeO+Tn8="
	var sep string = ":"

	signer, err := signing.NewSigner(key, sep, salt)
	if err != nil {
		panic(err)
	}

	signed := signer.Sign("the-quick-brown-fox")
	fmt.Print(signed)

	unsigned, err := signer.Unsign(signed)
	switch err {
	case signing.ErrBadSignature:
		fmt.Printf("Unsign error: %v", err)
	default:
		panic(err)
	}
	fmt.Print(unsigned)
