加密在节点JS PHP 7解密

Question

在PHP 5.6有很多是非常完美的解决方案是基于http://php.net/manual/en/function.mcrypt-decrypt.php

是例如

public function encrypt($data) 
{ 
    //don't use default php padding which is '\0' 
    $pad = $this->blocksize - (strlen($data) % $this->blocksize); 
    $data = $data . str_repeat(chr($pad), $pad); 
    return bin2hex(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, 
     $this->encryptKey, 
     $data, MCRYPT_MODE_CBC, $this->iv)); 
} 

但PHP7有警告不鼓励使用这个功能。

“这个函数从PHP 7.1.0开始已经被取消了，依靠这个函数是非常不鼓励的。”

使用两端关键字进行安全加密的任何想法; PHP + Node.js？

LibMcrypt是在2007年的更多信息被遗弃https://wiki.php.net/rfc/mcrypt-viking-funeral

你必须使用的OpenSSL加密http://php.net/manual/en/function.openssl-encrypt.php

PHP

<?php 
$textToEncrypt = "Secret Text to Encrypt"; 
$encryptionMethod = 'aes-256-cbc'; 
$secretHash = "315a5504d921f8327f73a356d2bbcbf1"; // <---- you have to use some persistent key. 

$iv_size = openssl_cipher_iv_length($encryptionMethod); 
$iv = openssl_random_pseudo_bytes($iv_size); 

//To encrypt 
$encryptedMessage = openssl_encrypt($textToEncrypt, $encryptionMethod, $secretHash, 0, $iv); 

//Concatenate iv with data 
$encryptedMessageWithIv = bin2hex($iv) . $encryptedMessage; 

//To Decrypt 
$iv_size = openssl_cipher_iv_length($encryptionMethod); 
$iv = hex2bin(substr($encryptedMessageWithIv, 0, $iv_size * 2)); 

$decryptedMessage = openssl_decrypt(substr($encryptedMessageWithIv, $iv_size * 2), $encryptionMethod, $secretHash, 0, $iv); 

echo "Encrypted: $encryptedMessageWithIv <br>Decrypted: $decryptedMessage";

周的Node.js（我真的不使Node.js的程序员，可以有更有效的方法）

var data = "ad699a2537ec2a7f699acbf97ca0080eh3z5EgvnTAvlc76YeR6HdWPmkDDt+pHiG//qo7xnqyQ="; 
var key = "315a5504d921f8327f73a356d2bbcbf1"; 
var iv = new Buffer(data.substring(0,32), 'hex'); 
var dec = crypto.createDecipheriv('aes-256-cbc',key,iv); 
var decrypted = Buffer.concat([dec.update(new Buffer(data.substring(32),'base64')), dec.final()]); 
console.log('DECRYPTED TEXT: '+decrypted.toString());
