【经验总结】
1.注册码位数必须大于用户名位数
2.循环判断用户名在字符表的位置，即esi*2+494E20，字符表按照a * b * c * d * f *....排列，*的位置是乱序字符，根
据用户名的位置数找到乱序字符，即esi*2+494E21的位置，esi等于顺序排列字符的位置（如果用户名字符>34h（102）即字符表中Z的位置就填充字母P,例如用户名：~！@#￥%……&*（）~！@#￥ ，注册码：PPPPPPPPPPPPPPPP 就能注册成功，感谢一衰烟雨鹭影依凌
版主提醒。）
3.如果用户名不等于16位，把填充字符表从左开始补够16位
4.比较注册码是否和算出来的注册码比较
一组可用的注册码
Name:thdzhqg
Registration Code:PkIFkdMLdQsBcmpJ
