NodeJS加密加密到前端javascript解密 [英] NodeJS Crypto encryption to front end javascript decryption

问题描述

我在寻找AES256 CBC解密客户端，

在nodeJS中我使用此功能进行加密：

  exports.encrypt = function（txt，cryptkey）{
 var cipher = crypto.createCipher（'aes-256-cbc'，cryptkey）; 
 var crypted = cipher.update（txt，'utf8'，'hex'）; 
 crypted + = cipher.final（'hex'）; 
 
 console.log（crypted）; 
返回加密; 
 
}; 
  

但我似乎无法在任何客户端库（JSAES.js，SJCL我的猜测是与base64 / hex编码解码有关，任何指针？

解决方案

请查看 CryptoJS 项目：

以下是AES256 CBC加密/解密的示例：

包含：

 < script src =http://crypto-js.googlecode.com/svn/tags/ 3.1.2 /建造/汇总/ aes.js>< /脚本> 
< script src =http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/mode-cfb-min.js>< / script> 
  

JS：

  var passPhrase =Secret Phassphrase; 
 
 var encrypted = CryptoJS.AES.encrypt（Message，passPhrase，{mode：CryptoJS.mode.CFB}）; 
 var decryptpted = CryptoJS.AES.decrypt（encrypted，passPhrase，{mode：CryptoJS.mode.CFB}）; 
 
 console.log（'encrypted'，encrypted）; 
 console.log（'decryptpted'，decryptpted.toString（CryptoJS.enc.Utf8））;

I'm looking for AES256 CBC decryption client side,

in nodeJS I use this function to encrypt:

exports.encrypt = function(txt, cryptkey){
  var cipher = crypto.createCipher('aes-256-cbc',cryptkey);
  var crypted = cipher.update(txt,'utf8','hex');
  crypted += cipher.final('hex');

  console.log(crypted);
  return crypted;

};

but I can't seem to work with it in any client side library (JSAES.js, SJCL.js, pidcrypt)

my guess is it has something to do with the base64/hex encoding decoding, any pointers?

解决方案

Please have a look at the CryptoJS project:

Here is an example of AES256 CBC encryption / decryption:

Include:

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/components/mode-cfb-min.js"></script>

JS:

var passPhrase = "Secret Phassphrase";

var encrypted = CryptoJS.AES.encrypt("Message", passPhrase, { mode: CryptoJS.mode.CFB });
var decrypted = CryptoJS.AES.decrypt(encrypted, passPhrase, { mode: CryptoJS.mode.CFB });

console.log('encrypted', encrypted);
console.log('decrypted', decrypted.toString(CryptoJS.enc.Utf8));
