Ok, I got the MD4 hash running, but DES still does not work.

Can you help me with java ?

Here is my code:

String magicKey="KGS!@#$%";
String password="1234567";
byte[] passwordByte17=password.getBytes("windows-1252");
SecretKeyFactory desKeyFac=SecretKeyFactory.getInstance("DES");
SecretKey desKey=desKeyFac.generateSecret(new
desCipher = Cipher.getInstance("DES");
desCipher.init(Cipher.ENCRYPT_MODE, desKey);
byte[] desHash=desCipher.doFinal(passwordByte17);

The final desHash is not the same comparing to what a smbpasswd

What is wrong ?
