Question

我正在尝试创建一个nodejs服务来加密数据并发送到第三方服务器。

节点中的结果与php不同（php是对的）。

这是节点代码（PHP代码已注释）：

var crypto = require('crypto');
var Buffer = require('buffer').Buffer;

function encodeBase64 = function(data){
    //return base64_encode(data); //php code
    return new Buffer(data).toString('base64');
}

function decodeBase64(data){
    //data = base64_decode(data); //PHP code    
    return new Buffer(data, 'base64').toString("binary");
}

错误在这里，节点中的输出是不同的：

function encrypt_3DES(message, key){
    //PHP code:
    //$bytes = array(0,0,0,0,0,0,0,0);
    //$iv = implode(array_map("chr", $bytes));
    //$ciphertext = mcrypt_encrypt(MCRYPT_3DES, $key, $message, MCRYPT_MODE_CBC, $iv);
    //return $ciphertext;

    var bytes = [0,0,0,0,0,0,0,0];
    var iv = String.fromCharCode.apply(String, bytes);
    var cipher = crypto.createCipheriv("des-ede3-cbc", key, iv);
    var crypted = cipher.update(""+message, 'utf8', 'hex');
    crypted += cipher.final('hex');

    console.log("JS output hex: " + crypted);
    console.log("PHP output hex: f318a5942e4f6d5a3c14fd11f8879540");
    return crypted;
}

在这里：

function mac256(ent, key, input_format){
    //return hash_hmac('sha256', ent, key, true); //(PHP 5 >= 5.1.2)

    var hash = crypto.createHmac('SHA256', key).update(ent, input_format).digest();
    return hash;
}

使用此功能运行全部：

function run(){
    var data1 = "1446117555";
    var data2 = "eyJEU19NRVJDSEFOVF9BTU9VTlQiOiIxNDUiLCJEU19NRVJDSEFOVF9PUkRFUiI6IjE0NDYx";
    data2 += "MTc1NTUiLCJEU19NRVJDSEFOVF9NRVJDSEFOVENPREUiOiIzMjcyMzQ2ODgiLCJEU19NRVJDSEF";
    data2 += "OVF9DVVJSRU5DWSI6Ijk3OCIsIkRTX01FUkNIQU5UX1RSQU5TQUNUSU9OVFlQRSI6IjAiLCJEU1";
    data2 += "9NRVJDSEFOVF9URVJNSU5BTCI6IjEiLCJEU19NRVJDSEFOVF9NRVJDSEFOVFVSTCI6Imh0dHA6X";
    data2 += "C9cL3d3dy5iYW5jc2FiYWRlbGwuY29tXC91cmxOb3RpZmljYWNpb24ucGhwIiwiRFNfTUVSQ0hB";
    data2 += "TlRfVVJMT0siOiJodHRwOlwvXC93d3cuYmFuY3NhYmFkZWxsLmNvbVwvdXJsT0sucGhwIiwiRFN";
    data2 += "fTUVSQ0hBTlRfVVJMS08iOiJodHRwOlwvXC93d3cuYmFuY3NhYmFkZWxsLmNvbVwvdXJsS08ucGhwIn0=";

    var keyb64 = "sq7HjrUOBfKmC576ILgskD5srU870gJ7";
    var decodedKey = decodeBase64(keyb64);

    var key3des = encrypt_3DES(data1, decodedKey);

    var res = mac256(data2, key3des, 'base64');

    console.log("JS mac256: ", encodeBase64(res));
    console.log("PHP mac256: QfLVUv4nF2Nw7jBAkw0w8H0eRlwh2E1w/ZlKHdA2Sq0=");
    return encodeBase64(res);
}

Node.js 3Des和HMAC-SHA256，带有PHP代码的加密模块
