Enable DCI debugging on Gigabyte-BKi5HA-7200
--------------------------------------------

The Gigabyte-BKi5HA-7200 (Kabylake i5-7200 processor) can be debugged with only a USB debug cable, a
special cable that crosses only the data signals and has the power signals
removed. You can buy these cables at i.e. https://www.datapro.net/products/usb-3-0-super-speed-a-a-debugging-cable.html
The hurdle you have to overcome  before you can access DCI however is that you
need to set some bits in hardware that first enable DCI and also enable the debug port so that DCI can control the cores.
There are lots of guides in howto patch the BIOS but only these two really describes all the steps using only freely accessible tools:

## Crypter.java
package mobi.bbase.ahome.utils;

import java.io.ByteArrayOutputStream;
import java.util.Random;


/**
 * 加密解密QQ消息的工具类. QQ消息的加密算法是一个16次的迭代过程，并且是反馈的，每一个加密单元是8字节，输出也是8字节，密钥是16字节
 * 我们以prePlain表示前一个明文块，plain表示当前明文块，crypt表示当前明文块加密得到的密文块，preCrypt表示前一个密文块
 * f表示加密算法，d表示解密算法 那么从plain得到crypt的过程是: crypt = f(plain &circ; preCrypt) &circ;
