golang中sha256、md5加密，base64encode、base64decode

package tool

import (
	"crypto/md5"
	"crypto/sha256"
	"encoding/base64"
	"encoding/hex"
	"fmt"
	"io"
)

func EncoderSha256(data string) string {
	h := sha256.New()
	h.Write([]byte(data))
	sum := h.Sum(nil)

	//由于是十六进制表示，因此需要转换
	s := hex.EncodeToString(sum)
	return string(s)
}

func Md5(data string) string {
	w := md5.New()
	io.WriteString(w, data)
	bydate := w.Sum(nil)
	result := fmt.Sprintf("%x", bydate)
	return result
}

func Base64Encode(data string) string {
	return base64.StdEncoding.EncodeToString([]byte(data))
}
func Base64Decode(data string) ([]byte, error) {
	return base64.StdEncoding.DecodeString(data)
}

用户名密码加密+加时间戳盐

func main() {
	h := sha256.New()
	_, _ = h.Write([]byte("password"))
	// 加盐
	salt := 1639992878
	_, _ = io.WriteString(h, strconv.Itoa(salt))
	sum := h.Sum(nil)
	fmt.Println(sum)
	s := hex.EncodeToString(sum)
	fmt.Println(s)

	a := "4dcdee6fe15be49c956fee902c0a6e2a82f85bfea9c8606f5448114857ad34fe"
	fmt.Println(a == s)

}

md5加密+加盐封装

const (
	RANDOM_STR = "qwertyuioplkjhgfdsazxcvbnm123456789.+-*/0=_-)(*&^%$#@!~"
)

//小写的
func Md5Encode(data string) string{
	h := md5.New()
	h.Write([]byte(data)) // 需要加密的字符串为 123456
	cipherStr := h.Sum(nil)
	return  hex.EncodeToString(cipherStr)
}

//大写
func MD5Encode(data string) string{
	return strings.ToUpper(Md5Encode(data))
}

func ValidatePasswd(plainpwd,salt,passwd string) bool{
	return Md5Encode(plainpwd+salt)==passwd
}

func MakePasswd(plainpwd,salt string) string{
	return Md5Encode(plainpwd+salt)
}

func GenerateSalt(length int) (str string) {
	// 生成指定位数的随机字符串
	rand.Seed(time.Now().UnixNano()) // 随机种子
	for i := 0; i < length; i++ {
		ii := rand.Intn(len(RANDOM_STR))
		str += string(RANDOM_STR[ii])
	}
	return
}
