Node.js Crypto类以更新的版本返回不同的结果

以下代码为单点登录按钮生成HTML输出，并将其添加到页面中。在节点版本0.5.x中，服务器在按钮单击时接受密钥，但在升级到0.10.x后，密钥不起作用并产生不同的输出。没有错误。加密类是否改变了？请注意，密钥，网址和iv已被稍微更改以避免发布安全信息，但长度正确。Node.js Crypto类以更新的版本返回不同的结果

您是否尝试过'Buffer.concat'代替+ =？我回答了另一个问题，“+ ='无法正常工作。 –

你好，你已经试过了吗？ –

对不起，是的，这工作 – wdhilliard

看来 - 至少在以后的版本中的NodeJS - 这Buffer.concat()需要，而不是+=操作。

沃金代码：

var crypto = require('crypto'); 
var ecr = function(str) 
{ 
    var cipher = crypto.createCipher('aes-256-cbc', 'passphase'); 
    var cryptedBuffers = [cipher.update(new Buffer(str))]; 
    cryptedBuffers.push(cipher.final()); 
    var crypted = Buffer.concat(cryptedBuffers); 
    return crypted; 
}; 
var dcr = function(str) 
{ 
    var dcipher = crypto.createDecipher('aes-256-cbc', 'passphase'); 

    var dcryptedBuffers = [dcipher.update(new Buffer(str))]; 
    dcryptedBuffers.push(dcipher.final()); 
    var dcrypted = Buffer.concat(dcryptedBuffers) 
     .toString('utf8'); 
    return dcrypted; 
}; 

console.log(dcr(ecr('hello test')));
