Android中DatatypeConverter的替代品

我尝试在Android中实现算法AES 128,但它不起作用,问题是 import javax.xml.bind.DatatypeConverter;

DatatypeConverter.parseHexBinary(key) 和 DatatypeConverter.printBase64Binary(finalData)

有替代方案吗？

我的方法:

private static final String ALGORIT = "AES";

public static String encryptHackro(String plaintext, String key)
throws NoSuchAlgorithmException, NoSuchPaddingException,
InvalidKeyException, IllegalBlockSizeException,
BadPaddingException, IOException, DecoderException {


    byte[] raw = DatatypeConverter.parseHexBinary(key);

    SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
    Cipher cipher = Cipher.getInstance(ALGORITMO);
    cipher.init(Cipher.ENCRYPT_MODE, skeySpec);

    byte[] cipherText = cipher.doFinal(plaintext.getBytes(""));
    byte[] iv = cipher.getIV();

    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    outputStream.write(iv);
    outputStream.write(cipherText);

    byte[] finalData = outputStream.toByteArray();

    String encodedFinalData = DatatypeConverter.printBase64Binary(finalData);

    return encodedFinalData;

}

我看到其他人的答案,但我无法实施解决方案.

解

我解决了我的问题

compile 'commons-codec:commons-codec:1.3'

我使用android.util.Base64 for Android

不兼容/替换

DatatypeConverter.parseHexBinary 
org.apache.commons.codec.binary.Hex.decodeHex(key.toCharArray());




DatatypeConverter.printBase64Binary(finalData);
android.util.Base64.encodeToString(finalData, 16) 



DatatypeConverter.parseBase64Binary(encodedInitialData);
org.apache.commons.codec.binary.Hex.decodeHex(key.toCharArray());
