Decrypt special symbol

[liketanglung]

Hi all,
I have just gotten a java applet template. And i can't understand some code, ex:

String s = (new StringBuilder()).append(a).append(a.a("X|~4Nws|<Ksu!")).toString();

or

byte abyte0[] = s.getBytes(a.a("]FX9(-&-1d"));

I can't get "X|~4Nws|<Ksu!" and "]FX9(-&-1d" is what?
Who can help me please :confused:

All code of this:

import java.io.PrintStream;
import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Arrays;

public class b
{
    public static byte[] a(String a)
        throws UnsupportedEncodingException, NoSuchAlgorithmException
    {
        String s = (new StringBuilder()).append(a).append(a.a("X|~4Nws|<Ksu!")).toString();
        byte abyte0[] = s.getBytes(a.a("]FX9(-&-1d"));
        MessageDigest messagedigest = MessageDigest.getInstance(a.a("E_\024"));
        messagedigest.update(abyte0);
        return messagedigest.digest();
    }
    public static boolean a(String a, byte a[])
        throws UnsupportedEncodingException, NoSuchAlgorithmException
    {
        if(Arrays.equals(a(a), a))
        {
            return true;
        } else
        {
            System.out.println(a.a("Cgxzw5cuofh{j1"));
            return false;
        }
    }
}
