	"gitee.com/gricks/sign"
)

func main() {
	// AES-32-256
	key := []byte("123456789-123456-123456789-12345")
	fmt.Println(len(key))
	s, err := sign.NewSign(key)
	if err != nil {
		panic(err)
	}

	// plaintext must be a multiple of the block size
	plaintext := []byte("hello world man!")
	fmt.Println(len(plaintext))
	ciphertext, err := s.Encryp(plaintext)
	if err != nil {
		panic(err)
	}

	plaintext, err = s.Decryp(ciphertext)
	if err != nil {
		panic(err)
	}
	fmt.Println(string(plaintext))

	plaintext, err = s.Decryp(ciphertext)
