why is the servername secret. This shouzld be a public server.
Try the following program
import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
public class CheckCrypto {
public static void main(String[] args){
String cryptoAlg = "AES";
try{
SecretKeySpec keyspec = new SecretKeySpec(new byte[32], cryptoAlg);
Cipher c = Cipher.getInstance(cryptoAlg + "/CBC/NoPadding");
c.init(Cipher.ENCRYPT_MODE, keyspec, new IvParameterSpec(new
byte[16]));
}
catch(Exception e){
System.err.println("************ The Java Virtual Machine can't
handle strong cryptography.\n************ This will lead to problems with some
services and subsystems!");
}
}
}
If you get the exception-message, you still need to install the
unlimimted strength cryptography policy files.
