    注解
    HMACSHA256 是一种加密哈希算法,它是从 SHA-256 哈希函数构建的,用作基于哈希的消息验证代码(HMAC)。 HMAC 进程将密钥与消息数据混合,使用哈希函数对结果进行哈希运算,再次混合使用密钥的哈希值,然后再次应用哈希函数。 输出哈希的长度为256位。

    如果发送方和接收方共享密钥,则可以使用 HMAC 来确定通过不安全通道发送的消息是否已被篡改。 发件人计算原始数据的哈希值,并以单个消息形式发送原始数据和哈希值。 接收方重新计算收到的消息上的哈希值,并检查计算的 HMAC 是否与传输的 HMAC 匹配。

    对数据或哈希值所做的任何更改都将导致不匹配,因为更改消息和重现正确的哈希值需要使用机密密钥知识。 因此,如果原始和计算所得的哈希值匹配,则将对消息进行身份验证。

    HMACSHA256 接受任意大小的密钥,并产生长度为256位的哈希序列。

    我试图创建签名使用HMAC-SHA256算法,这是我的代码。

    我使用US ASCII编码。

    final Charset asciiCs = Charset.forName("US-ASCII");

    final Mac sha256_HMAC = Mac.getInstance("HmacSHA256");

    final SecretKeySpec secret_key = new javax.crypto.spec.SecretKeySpec(asciiCs.encode("key").array(), "HmacSHA256");

    final byte[] mac_data = sha256_HMAC.doFinal(asciiCs.encode("The quick brown fox jumps over the lazy dog").array());

    String result = "";

    for (final byte element : mac_data)

    {

    result += Integer.toString((element & 0xff) + 0x100, 16).substring(1);

    }

    System.out.println("Result:[" + result + "]");

    我从上面的代码得到的结果是:

    f7bc83f430538424b13298e6aa6fb143ef4d59a14946175997479dbc2d1a3cd8

    这与wiki中显示的相同

    HMAC_SHA256("key", "The quick brown fox jumps over the lazy dog") = 0x f7bc83f430538424b13298e6aa6fb143ef4d59a14946175997479dbc2d1a3cd8

    除了0x。

    我正在寻找想法/意见,如果我做的一切正确,或可能是我可以改进我的代码。

  • I play with digital signatures using node.... For test purpose, I created a digital signature of some XML data, first using only SHA256, then using RSA-SHA256.The thing that puzzles me is that both me...

    I play with digital signatures using node.js. For test purpose, I created a digital signature of some XML data, first using only SHA256, then using RSA-SHA256.

    The thing that puzzles me is that both methods of signing create exactly the same signature. Both signatures are identical. If they're identical, then why two different methods (SHA256 vs. RSA-SHA256)?

    I include code below:

    var crypto = require('crypto'),

    path = require('path'),

    fs = require('fs'),

    pkey_path = path.normalize('private_key.pem'),

    pkey = '';

    function testSignature(pkey) {

    var sign1 = crypto.createSign('RSA-SHA256'),

    sign2 = crypto.createSign('SHA256');

    fs.ReadStream('some_document.xml')

    .on('data', function (d) {

    sign1.update(d);

    sign2.update(d);

    })

    .on('end', function () {

    var s1 = sign1.sign(pkey, "base64"),

    s2 = sign2.sign(pkey, "base64");

    console.log(s1);

    console.log(s2);

    });

    }

    // You need to read private key into a string and pass it to crypto module.

    // If the key is password protected, program execution will stop and

    // a prompt will appear in console, awaiting input of password.

    testSignature(fs.readFileSync(pkey_path));

    The code above outputs some string, which is the signature, and then again exactly the same string, which is also a signature of the same data, but created with - supposedly - different algorithm, yet it's identical with previous one...

    解决方案

    A signature cannot be created by SHA256 alone.

    SHA256 is a hashing algorithm; i.e. an algorithm creating a short fingerprint number representing an arbitrary large amount of data. To produce a signature, this fingerprint still has to be treated somehow to allow identification of the holder of some private signature key. One such treatment is to encrypt the fingerprint using the private key of a rsa key pair allowing others to decrypt the result using the associated public key and so verify that the keeper of the private key indeed must have been the signer.

    In the context of your crypto API that RSA encryption scheme either is the default treatment when the treatment is not explicitly named, or the kind of treatment is deduced from the private key you use as parameter in the sign call --- if it is a RSA private key, it uses RSA; if it is a DSA key, it uses DSA; ...
