[AS3]as3加密解密的问题

I want tp encrypt and decrypt string, with defined salt. But the result must be same if the code run in java and adobe flex. The main goal is: the app in adobe flex will be generate a string that can be decrypt in server using java.

I use this flex library http://crypto.hurlant.com/demo/

Try to 'Secret Key' Tab. I want to use AES Encryption, 'CBC' or 'PKCS5'.

var k:String = "1234567890123456"; 
var kdata:ByteArray = Hex.toArray(k); 
var txt:String = "hello"; 
var data:ByteArray = Hex.toArray(Hex.fromString(txt));; 
var name:String = "simple-aes-cbc"; 
var pad:IPad =new PKCS5(); 
var mode:ICipher = Crypto.getCipher(name, kdata, pad); 
pad.setBlockSize(mode.getBlockSize()); 
mode.encrypt(data); 
encrypted.text=Hex.fromArray(data); 
trace(Hex.fromArray(data)); 

And here is the code in java

String plaintext = "hello"; 
String key = "1234567890123456"; 
 
SecretKey keyspec = new SecretKeySpec(key.getBytes(), "AES");        
 
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding"); 
cipher.init(Cipher.ENCRYPT_MODE,keyspec); 
byte[] encrypted = cipher.doFinal(plaintext.getBytes()); 
 
BASE64Encoder base64 = new BASE64Encoder(); 
String encodedString = base64.encode(encrypted); 
 
System.out.println(encodedString); 

Why the result is not same? Can you guys provide the sample with the same result both of java and flex (encrypt and decrypt)? And if I want to change the paramater, for example, from cbc to ebc, which line that need to be changed?

Thanks!
