在Android 上如何加密/解密 __CODE__和其他文件有一个很好的例子__CODE__吗？我正在开发一个需要加密/解密数据的项目,但我不确定该怎么做.

我通过swift编写应用程序,我需要AES加密和解密功能,我从另一个.Net解决方案接收加密数据,但我找不到要做的事情.

这是我的.net加密:

 public static byte[] AES_Encrypt(byte[] bytesToBeEncrypted, byte[] passwordBytes)
    {
        byte[] encryptedBytes = null;

        byte[] saltBytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8 };

        using (MemoryStream ms = new MemoryStream())
        {
            using (RijndaelManaged AES = new RijndaelManaged())
            {
                AES.KeySize = 256;
                AES.BlockSize = 128;

                var key = new Rfc2898DeriveBytes(passwordBytes, saltBytes, 1000);
                AES.Key = key.GetBytes(AES.KeySize / 8);
                AES.IV = key.GetBytes(AES.BlockSize / 8);

                AES.Mode = CipherMode.CBC;

                using (var cs = new CryptoStream(ms, AES.CreateEncryptor(), CryptoStreamMode.Write))
                {
                    cs.Write(bytesToBeEncrypted, 0, …

我的问题是如何加密字符串:

String AndroidId;

@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.download_movie_activity);

  cancel = (Button)findViewById(R.id.img_cancle);

  linear= (LinearLayout)findViewById(R.id.progress);
  linear.setVisibility(View.GONE);

  String encrypted = "MzIyNTE2" + "OTQNzM4NTQ=";

  Log.e("Encrypt", encrypted);

  WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
  WifiInfo wInfo = wifiManager.getConnectionInfo();
  AndroidId = wInfo.getMacAddress();

  AndroidId=encrypted;

U如何加密我存储MAC地址的AndroidId.
