Share an example of a problem based on crypto-js encryption

Recently, I used PHP to build an HTML5 website for online streaming of movies/TV series. I used PHP’s curl for real-time crawling. I encountered a problem with JS encryption, so Google solved it, and I came up with this article. Summarize.

Let’s talk about js based on crypto-js Encryption

CryptoJS is an encryption class library written purely in javascript. Its GitHub warehouse address is github.com/brix/crypt...

We need it when using it QuoteThis js file, for the convenience I quoted the link on the CDN

The code

<script src="cdn.bootcss.com/crypto-js/3.1.9/crypto-js.js"></script>
<script>
var data = "en2JprK0nMyYgbd6dQO0O0OO0O0O" // 需要加密的字符串
var key_base="contentWindowHig"; // 加密秘钥的基值
var iv_base="contentDocuments"; // 加密所需iv基值
/**
 * 定义加密函数
 * @param  {[type]} a [形参，需要加密的值]
 * @return {[type]}   [加密后的值]
 */
 var get=function(a){
     var key_hash=CryptoJS.MD5(key_base); 
     var key=CryptoJS.enc.Utf8.parse(key_hash);
     var iv=CryptoJS.enc.Utf8.parse(iv_base);
     var res=CryptoJS.AES.encrypt(a,key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.ZeroPadding});
     return res.toString()
 }
    console.log(get(data)) // tPYJv39iEbdFD/UqNejyvkLG8ATdifyfE+BDeld2jWk=
</script>

Let’s talk about the same encryption and decryption of PHP

For The elegance of the article, php will use the same variable naming as js

Up code

// 定义变量
$data = "en2JprK0nMyYgbd6dQO0O0OO0O0O";
$key_base = "contentWindowHig";
$iv_base = "contentDocuments";
// 加密前处理
$key = md5('contentWindowHig');
$iv = $iv_base;
// 加密
$cryptText = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $data, MCRYPT_MODE_CBC, $iv);
$res = base64_encode($cryptText);
// 解密
$cryptText = base64_decode($res); 
$decode = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $cryptText, MCRYPT_MODE_CBC, $iv);
