nodejs crypto module vs crypto-js

问题描述

我对NodeJ很新，并试图弄清楚如何使用加密模块。在玩它的同时我注意到NodeJs中的crypto模块和crypto-js之间的区别：

I'm quite new to NodeJs and trying to figure out how to use the "crypto" module. While playing around with it I notice the difference between the "crypto" module in NodeJs and crypto-js:

使用crypto-js，我有：

With crypto-js, I have:

function SHA256Hash(password, salt, iteration) {
    var saltedpassword = salt + password;
    var sha256 = CryptoJS.algo.SHA256.create();
    for(var i = 0; i < iteration; i++) {
            alert("saltedpassword = " + saltedpassword);
            sha256.update(saltedpassword);
            var saltedpassword = sha256.finalize();
            sha256.reset();
    }
    return saltedpassword.toString(CryptoJS.enc.Base64);
}

然后致电：

var hashedPassword = SHA256Hash("123456789", "ASIN", 3)

和接收：

saltedpassword = ASIN123456789
saltedpassword = 3362d80b757d14bfe18c01f6a003ed38a3a4a3dcab0417efb457b71740e21411
saltedpassword = 6020c992a9b7cd3ca9e95b9a3e21b64911edb7983b3dd77bdcecda19f2756987

使用crypto模块，我写道：

With "crypto" module, I wrote:

function SHA256Hash(password, salt, iteration) {
    var saltedpassword = salt + password;
    for(var i = 0; i < iteration-1; i++) {
            console.log("saltedpassword = "+saltedpassword)
            var sha256 = crypto.createHash('sha256');
            sha256.update(saltedpassword);
            var saltedpassword = sha256.digest('hex');
    }
    console.log("saltedpassword = "+saltedpassword)
    var sha256 = crypto.createHash('sha256');
    sha256.update(saltedpassword);
    return sha256.digest('base64');
}

然后致电：

var hashedPassword = SHA256Hash("123456789", "ASIN", 3);

并且收到：

saltedpassword = ASIN123456789
saltedpassword = 3362d80b757d14bfe18c01f6a003ed38a3a4a3dcab0417efb457b71740e21411
saltedpassword = 4795d40ae8ae797f0ce51dfe4b496bca68f6d1f4a264f4ca52348ddd65a2988d

前两项是相同的，但第三项是不同的。我错过了什么吗？

The first two items are the same but the third item is different. Did I miss out something ?

已编辑：与Jasypt相比，CryptoJs生成类似的密钥。我的问题是如何调整加密模块，使其生成与CryptoJS和Jasypt相同的密钥。

Edited: As I compare to the Jasypt, CryptoJs generates similar keys. My question is how to tune "crypto" module to make it generate the same keys as CryptoJS and Jasypt do.

推荐答案

显然我无法为怪异的答案添加评论，所以我会在这里写一下：

Apparently I can't add comments to freakish's answer, so I'll write it here instead:

reset（）工作正常。重要的区别是你在迭代循环中将散列输出转换为十六进制字符串。

reset() works fine. The significant difference is you're converting the hash output to a hex string within the iteration loop.
