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)

}
