rsa数据加密无大小限制——golang实现

目录

• • 一、MD5加解密
  • 二、HmacSHA256加解密
  • 三、获取uuid、时间戳

一、MD5加解密

import (
	"crypto/md5"
	"encoding/hex"
)

func md5Encrypt(txt string) string {
	m5 := md5.New()
	m5.Write([]byte(txt))
	txtHash := hex.EncodeToString(m5.Sum(nil))
	return txtHash
}

二、HmacSHA256加解密

import (
	"crypto/hmac"
	"crypto/sha256"
	"encoding/base64"
)

func HmacSha256ToBase64(key string, data string) string {
	mac := hmac.New(sha256.New, []byte(key))
	_, _ = mac.Write([]byte(data))
	encode := mac.Sum(nil)
	return base64.StdEncoding.EncodeToString(encode)
}

三、获取uuid、时间戳

import (
	"github.com/google/uuid"
	"strconv"
	"time"
)
func main() {
	now := time.Now()
	time_1 := strconv.FormatInt(now.Unix(), 10)      // 10位时间戳
	time_2 := strconv.FormatInt(now.UnixMilli(), 10) // 13位时间戳
	println(time_1)
	println(time_2)
	println(uuid.New().String())
}
