Question

我有以下要移植到Node.js的Java代码：

import java.security.InvalidAlgorithmParameterException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;

import javax.crypto.BadPaddingException;
import javax.crypto.Cipher;
import javax.crypto.IllegalBlockSizeException;
import javax.crypto.NoSuchPaddingException;
import javax.crypto.spec.SecretKeySpec;
import javax.xml.bind.DatatypeConverter;

public class ChiperExample {

    private static final String CIPHER_ALGORITHM = "AES";

    public static String decrypt(final String encryptedMessage, final String hexEncodedKey)
        throws InvalidKeyException,
        InvalidAlgorithmParameterException,
        NoSuchAlgorithmException,
        NoSuchPaddingException,
        IllegalBlockSizeException,
        BadPaddingException {
        byte[] key = DatatypeConverter.parseHexBinary(hexEncodedKey);
        SecretKeySpec secretKeySpec = new SecretKeySpec(key, CIPHER_ALGORITHM);
        Cipher encryptCipher = Cipher.getInstance(CIPHER_ALGORITHM);
        encryptCipher.init(Cipher.DECRYPT_MODE, secretKeySpec);
        byte[] decrypted = encryptCipher.doFinal(DatatypeConverter.parseHexBinary(encryptedMessage));
        return new String(decrypted);
    }

    public static String encrypt(final String cleanMessage, final String hexEncodedKey)
        throws InvalidKeyException,
        InvalidAlgorithmParameterException,
        NoSuchAlgorithmException,
        NoSuchPaddingException,
        IllegalBlockSizeException,
        BadPaddingException {
        byte[] key = DatatypeConverter.parseHexBinary(hexEncodedKey);
        SecretKeySpec secretKeySpec = new SecretKeySpec(key, CIPHER_ALGORITHM);
        Cipher encryptCipher = Cipher.getInstance(CIPHER_ALGORITHM);
        encryptCipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);
        byte[] encrypted = encryptCipher.doFinal(cleanMessage.getBytes());
        String encryptedHexString = DatatypeConverter.printHexBinary(encrypted);
        return encryptedHexString.toLowerCase();
    }
}

这是我尝试使用流使用Node.js

const crypto = require('crypto');

var decipher = crypto.createDecipher('aes128', 'password');
decipher.setAutoPadding(false);
var msisdn = decipher.update('a6ee2954cb6248dc6bc48ca2109fa1d8', 'hex', 'utf8');
msisdn += decipher.final('utf8');

console.log(msisdn)

这两个版本均产生正确长度的相同输出（与输入长度相同），但是此输出与在相同输入缓冲区上操作的Java版本的解密器所产生的明文不同。如何设置像上面配置的Java解密那样的Node.js解密？

将Java解密函数转换为Node.js
