Difference between demo outputs and local test outputs

[GoogleCodeExporter]

Hello,

I have a problem, 

I would like to crypt with HMAC SHA1 algorithm the string "113004281321398000" 
with the key "Mj\{NTA=MTA(5874"

To do so I use AS3CRYPTO demo here crypto:hurlant:com/demo, I choose HMAC 
panel, sha1. Then I paste my key and the string data in text format, I choose 
base64 for output format.

It outputs [B]GJdYxXIlAwT1FdXtaVQIdZmfKJk=[/B]

But Under FLASH CS5 I write this code to crypt :

[CODE]
import com.hurlant.util.Base64;
import com.hurlant.util.Hex;
import com.hurlant.crypto.hash.HMAC;
import com.hurlant.crypto.Crypto;
import com.hurlant.crypto.hash.IHash;
import com.hurlant.crypto.hash.SHA1;

var key_str:String = 'Mj\{NTA=MTA(5874';
var str:String = '113004281321398000';

var key:ByteArray = Hex.toArray(Hex.fromString(key_str));
var pt:ByteArray = Hex.toArray(Hex.fromString(str));

var hmac:HMAC = Crypto.getHMAC('hmac-sha1');
//var hmac:HMAC = new HMAC(new SHA1());

var secret:ByteArray = hmac.compute(key, pt);
var result = Base64.encodeByteArray(secret);
//secret = Hex.fromArray(secret);
trace(result);

[/CODE]

And it outputs [B]HQLQpEclCPFaOp9tdPmKL0UiVLE=[/B]

This is confusing because the outputs are different between the demo and my 
test, I know that the right output is from the demo.

Do you know where is the problem?

Thanks

i solved it by using 

m.writeUTFBytes(msg.text);
instead of 
m.writeUTF(msg.text);
