Question

由于几天我试图弄清楚为什么我在javascript（cryptojs）和java不同的加密输出。我处于死胡同，不知道该改变什么，我想我会失去理智。这是完整的代码，应该很容易复制粘贴进行测试。你是我最后的希望。 ^^

plainText = plaintext
password = password
salt = 3FF2EC019C627B945225DEBAD71A01B6985FE84C95A70EB132882F88C0A59A55
iv = 3C46C00F42A6044A"

Javascript result = zbohHpV5RtmHiH3cKDY15w ==

Java结果= wVdRQiIqkyVlttkWpCMSpQ ==

Javascript html：已更新并将迭代更改为10

Answer 1

最后他们都是平等的，感谢pasimako把我带到路上。我不得不改变iv和salt转换为十六进制的方式以及iv的长度，如上所述，keySize和iterationCount变量也是未定义的。

这是完整的工作代码。

他们都应输出：

<强>的Javascript

var salt = "3FF2EC019C627B945225DEBAD71A01B6985FE84C95A70EB132882F88C0A59A55";

var plainText = "plaintext";
var iv = "12345678901234567890123456789012";

var key = CryptoJS.PBKDF2(password, CryptoJS.enc.Hex.parse(salt), {keySize: 128/32, iterations: 10});

var a = CryptoJS.AES.encrypt(plainText, key, {iv: CryptoJS.enc.Hex.parse(iv)}).ciphertext.toString(CryptoJS.enc.Base64);


var result = "encypted: " + a + "<br \>";
document.getElementById("result").innerHTML = result;
</script>

Java Main.class

public class main {

public static void main(String[] args) throws Exception {
    String result = Aes.encrypt("plaintext", "password", "3FF2EC019C627B945225DEBAD71A01B6985FE84C95A70EB132882F88C0A59A55", "12345678901234567890123456789012");
    System.out.println(result);

public class Aes { 
private static final int pswdIterations = 10;
private static final int keySize =  128;

public static String encrypt(String plainText, String password, String salt, String initializationVector) throws NoSuchAlgorithmException, NoSuchPaddingException, DecoderException, InvalidKeySpecException, InvalidKeyException, InvalidAlgorithmParameterException, IllegalBlockSizeException, BadPaddingException  {

Answer 2

首先，您的JavaScript代码是错误的。尝试下面的代码，看看你的keySize和iterationCount变量是未定义的。

Aes.generateKey = function(salt, passPhrase) {
  console.log(this.keySize);
  console.log(this.iterationCount);
  var key = CryptoJS.PBKDF2(
          passPhrase, 
          CryptoJS.enc.Hex.parse(salt),
          { keySize: this.keySize, iterations: this.iterationCount });
  return key;
 }

JavaScript的结果应该是Bttn5HNBIFDQ5hb1IbOFXQ ==

var password = "password";
var salt = "3FF2EC019C627B945225DEBAD71A01B6985FE84C95A70EB132882F88C0A59A55";

var plainText = "plaintext";
var iv = "3C46C00F42A6044A";

var key = CryptoJS.PBKDF2(password, CryptoJS.enc.Hex.parse(salt), {keySize: 128/32, iterations: 10000});

var a = CryptoJS.AES.encrypt(plainText, key, {iv: CryptoJS.enc.Hex.parse(iv)}).ciphertext.toString(CryptoJS.enc.Base64);

console.log(a);
