JS實(shí)現(xiàn)AES加密并與PHP互通的方法分析

<script type="text/JavaScript" src="/CryptoJS/aes.js"></script>
<script type="text/javascript" src="/CryptoJS/pad-zeropadding.js"></script>
<script type="text/javascript">
var data="test";//加密字符串
var key = CryptoJS.enc.Latin1.parse('@12345678912345!');//密鑰
var iv = CryptoJS.enc.Latin1.parse('@12345678912345!');//與密鑰保持一致
//加密
var data = JSON.stringify(data);//將數(shù)據(jù)對象轉(zhuǎn)換為json字符串
var encrypted = CryptoJS.AES.encrypt(data,key,{iv:iv,mode:CryptoJS.mode.CBC,padding:CryptoJS.pad.ZeroPadding});
encrypted=encodeURIComponent(encrypted);
document.write(decrypted);//輸出加密后的字符串
//解密
var data="加密的字符串";
//key和iv和加密的時(shí)候一致
 var decrypted = CryptoJS.AES.decrypt(data,key,{iv:iv,padding:CryptoJS.pad.ZeroPadding});
 decrypted=decrypted.toString(CryptoJS.enc.Utf8);
 document.write(decrypted);//輸出解密后的數(shù)據(jù)

$privateKey="@12345678912345!";
$iv="@12345678912345!";
//加密
$encrypted=mcrypt_encrypt(MCRYPT_RIJNDAEL_128,$privateKey,$data,MCRYPT_MODE_CBC,$iv);
echo base64_encode($encrypted);
//解密
$encryptedData=base64_decode($data);
$decrypted=mcrypt_decrypt(MCRYPT_RIJNDAEL_128,$privateKey,$encryptedData,MCRYPT_MODE_CBC,$iv);
$decrypted=rtrim($decrypted,"\0");//注意！解密出來的數(shù)據(jù)后面會出現(xiàn)六個(gè)紅點(diǎn)；這句代碼可以處理掉，從而不影響進(jìn)一步的數(shù)據(jù)操作
return $decrypted;
