nodeJS：无法获得加密模块给我正确的AES加密结果 [英] nodeJS: can't get crypto module to give me the right AES cipher outcome

问题描述

我试图使用nodeJS加密模块使用AES 128的ECB模式加密一些十六进制字符串。

为此，我使用以下代码：

  cryptoAES = function（sInput，sKey，bEncrypt）{
 return crypto（'AES- ECB'，sInput，sKey，bEncrypt）; 
}; 
 
 crypto = function（sAlgo，sInput，sKey，bEncrypt）{
 var result =; 
 if（bEncrypt）{
 var cipher; 
 var bKey = new Buffer（sKey，'hex'）; 
 var bInput = new Buffer（sInput，'hex'）; 
 
 cipher = crypto.createCipher（sAlgo，bKey）; 
 
 cipher.setAutoPadding（false）; 
 result = cipher.update（bInput，null，'hex'）; 
 result + = cipher.final（'hex'）; 
} 
 return result; 
}; 
  

当调用cryptoAES时：

  sKey ='12345678900987654321123456789001'
 
 sInput ='060123456789ABCDEF00000000000000'
  

我应该得到

  result ='FBECD5D02C5B7CD1055AAF86238D1E2F'
  pre> 
 
 
但我得到：
  result ='ea1f940da8e269b9e075c936bff6a1f7 '
  
任何想法我可能做错了什么？
解决方案
阅读 https：// github.com/joyent/node/issues/1318#issuecomment-1562766 ，您 需要 crypto.createCipheriv（）：
 
  cipher = crypto.createCipheriv（sAlgo，bKey，''）; 
  
生成所需结果。
 
I'm trying to use the nodeJS crypto module to encrypt some hex strings using the ECB mode of AES 128.

To do so, I'm using the following code:
cryptoAES = function (sInput, sKey, bEncrypt) {
    return crypto('AES-128-ECB', sInput, sKey, bEncrypt);
};

crypto = function (sAlgo, sInput, sKey, bEncrypt) {
    var result = "";
    if (bEncrypt){
        var cipher;
        var bKey = new Buffer(sKey, 'hex');
        var bInput = new Buffer(sInput, 'hex');

        cipher = crypto.createCipher(sAlgo, bKey);

        cipher.setAutoPadding(false);
        result = cipher.update(bInput, null, 'hex');
        result += cipher.final('hex');
    }
    return result;
};
When calling cryptoAES with:
sKey = '12345678900987654321123456789001'

sInput = '060123456789ABCDEF00000000000000'
I should get
result = 'FBECD5D02C5B7CD1055AAF86238D1E2F'
but I'm getting:
result = 'ea1f940da8e269b9e075c936bff6a1f7'
Any idea what I could be doing wrong?
解决方案
Reading https://github.com/joyent/node/issues/1318#issuecomment-1562766, you do need crypto.createCipheriv():
cipher = crypto.createCipheriv(sAlgo, bKey, '');
That generates the required result.
