go-md5

GO语言 MD5 四种实现方式/及 BASE64加解密​

第一种​

func md5_1(s string) {
	m := md5.New()
	m.Write([]byte (s))
	fmt.Println(hex.EncodeToString(m.Sum(nil)))
}

第二种​

func md5_2(s string) {
	m := md5.Sum([]byte (s))
	fmt.Println(hex.EncodeToString(m[:]))
}

第三种​

func md5_3(s string) {
	m := md5.Sum([]byte(s))
	fmt.Printf("%x", m)
	fmt.Println()
}

第四种​

func md5_4(s string) {
	m := md5.New()
	io.WriteString(m, s)
	fmt.Println(hex.EncodeToString(m.Sum(nil)))
}

解密​

hex.DecodeString(string)

Base64 加解密​

const (
	base64Table = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"
)
 
var coder = base64.NewEncoding(base64Table)
 
func Base64Encode(src []byte) []byte {
	return []byte(coder.EncodeToString(src))
}
 
func Base64Decode(src []byte) ([]byte, error) {
	return coder.DecodeString(string(src))
}

===============================分割线(另一种方法sursen)=========================================
//加密
base64.StdEncoding.EncodeToString([]byte])
//解密
base64.StdEncoding.DecodeString(string)
