hi..
we have an application in dotnet that should encrypt a string in
dotnet and send it to a java application (both application web but
both need credentrial to get in, so the password will be encrypted in
dotnet side sent as URL paramter to the other java webapp where it
willl be decrypted and used)

so as a test i'm trying to create acode in dotnet and code in java
that should encrypt the same string and produce the same encrypted
byte array, in dotnet:

        string plainText = "This is a test";
          byte[] keySalt = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9,
10, 11, 12, 13, 14, 15, 16 };

           byte[] input = Encoding.Default.GetBytes(plainText);
           Console.WriteLine(getBytes(input));

           // INIT the CIPHER and key
           RijndaelManaged AesCipher = new
RijndaelManaged();

           AesCipher.Key = keySalt;

           // init vector, don't know what that is, otherwise the
array is always different
           AesCipher.IV = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13, 14, 15, 16 };
           ICryptoTransform crypt = AesCipher.CreateEncryptor();

           // ENCRYPT
           byte[] cipherText =crypt.TransformFinalBlock(input, 0,
input.Length);

           Console.WriteLine(getBytes(cipherText));

in java

               String msg="This is a test";
      byte[] keySalt=new byte[]{1, 2, 3, 4, 5, 6,7, 8, 9,10, 11, 12, 13,
14, 15, 16};

      byte[] input=msg.getBytes();
      System.out.println(getBytes(input));

      // INIT the CIPHER and key

      Cipher aesChiper=Cipher.getInstance("AES");
      Key key=new SecretKeySpec(keySalt,"AES");
      aesChiper.init(Cipher.ENCRYPT_MODE,key);

      // ENCRYPT
      byte[] encBytes=  aesChiper.doFinal(msg.getBytes());

      System.out.println(getBytes(encBytes));

but the array in both platform comes out differently..
why?
