下面是一些javascript，它将一个pin加密为Format-0（无PAN）pin块。在本例中，它创建了一个随机DES ZPK（区域引脚键），但如果您愿意，可以使用固定的区域引脚键。它还使用CryptoJS。

(如果你需要，我有一个C#的例子)

_createPinblockFromPin: function(pin) {

    var pinBlockString = "1" + pin.length.toString() + pin;
    while (pinBlockString.length < 16) {

        var r = encoding.b2h((Math.random() * 0x100) & 255);
        pinBlockString += r.toString(8).toUpperCase();
    }
    return pinBlockString;
}

_createZpk: function() {

    var key = CryptoJS.enc.Hex.stringify(CryptoJS.lib.WordArray.random(16));
    return key.toUpperCase();
}

_encryptPinBlock: function(clearPinBlockHex, zpkHex) {

    var clearPinBlock = CryptoJS.enc.Hex.parse(clearPinBlockHex);
    var key = CryptoJS.enc.Hex.parse(zpkHex);

    key.words[4] = key.words[0];
    key.words[5] = key.words[1];

    var iv = CryptoJS.lib.WordArray.create(64 / 8);
    var options = { iv: iv, mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.NoPadding };
    var encrypted = CryptoJS.TripleDES.encrypt(clearPinBlock, key, options);
    var encryptedHex = encrypted.toString().toUpperCase();

    return encryptedHex;
}

用法是：

var clearPinBlock = this._createPinblockFromPin(pin);
var clearZpk = this._createZpk();
var ePinBlock = this._encryptPinBlock(clearPinBlock, clearZpk);

这是一个使用BouncyCastle.net的c#示例

// create zpk
var keyGenParams = new KeyGenerationParameters(new SecureRandom(), 128);
var keyGen = new DesEdeKeyGenerator();
keyGen.Init(keyGenParams);
var zpk = keyGen.GenerateKey();
System.Diagnostics.Debug.WriteLine($"zpk->{DataFormatter.ToHexString(zpk)}");

// create pinblock
var random = new Random();
var pinString = $"1{pin.Length}{pin}";
while (pinString.Length < 16) pinString += random.Next(0, 9).ToString();
var pinBlock = DataFormatter.HexStringToByteArray(pinString);

System.Diagnostics.Debug.WriteLine($"clearPinBlock->{DataFormatter.ToHexString(pinBlock)}");

// encrypt pinblock
var pinBlockZpk = new byte[8];
var keyParam = new DesEdeParameters(zpk);
var desEngine1 = new DesEdeEngine();
desEngine1.Init(true, keyParam);
desEngine1.ProcessBlock(pinBlock, 0, pinBlockZpk, 0);
System.Diagnostics.Debug.WriteLine($"pinBlockZpk->  {DataFormatter.ToHexString(pinBlockZpk)}");

请注意数据格式。ToHexString()只是一个实用程序，用于将byte[]转换为十六进制字符串以进行诊断。
