--------------------------------------------------------------------------------
【详细过程】
  这个软件笨鸟我先飞兄弟已经爆破过了,而且应用PBKILLER反编译了软件的源码,他把软件和反编译的代码给了我,我只是在阅读源码后,整理了一下算法,没有深入测试。
  
  从源码开始看起了,呵呵,先贴几个关键的。
  1、在系统启动时,应用程序调用检测是否注册的用户对象,判断是否注册、过期、调整过爱期、以及是否手工改过注册等。
  global type dotnew from application
  
  。。。。。。。。。
  
  
  integer rt_chk_value
  user_reg myreg
  event open;ulong l_handle
  ulong lu_class
  string ls_name
  
  rt_chk_value = myreg.f_check_reg()
  
  if rt_chk_value = -100 then
          messagebox("提示","系统时间有误!")
          halt close
  end if
  
  if rt_chk_value = -200 then
          messagebox("提示","注册码有误!")
          halt close
  end if
  
  if rt_chk_value = -300 then
          messagebox("提示","试用期到,请注册!电话:13336268237 网址:www.zcrj.net")
          open(w_wrcode)
          return
  end if
  
  if rt_chk_value = -400 then
          messagebox("提示","系统破坏,请联系开发商!")
          return
  end if
  
  下面的代码就是USER_REG用户对象,承担检测注册任务。
  global type user_reg from n_cst_numerical autoinstantiate
  end type
  global user_reg user_reg
  
  forward prototypes
  public function integer f_check_reg ()//检测是否过期、爱期调整、注册,内部调用f_checkregcode
  public function integer f_checkregcode (string reg_code)//关键的检查注册码的部分
  public function string f_encode (string source_str)//对注册表信息加密的部分
  public function string f_genpuzzle ()
  public function string f_genser ()
  public function string f_getdisk ()//获取硬盘序列号,与注册码生成有关
  public function string f_redreg (string xsxt_key)//读注册表
  public function integer f_setreg (string str_num,string str_info)//写注册表
  public function string f_swap1 (string str_input)
  public function string uf_patchstr (string userstr,integer userlen)
  end prototypes
  
  这里面其它的函数都是起迷惑作用的,呵呵。。。。。。。。。。。。。
  
  public function integer f_check_reg ();string ls_right
  string ls_wrong
  ulong l_handle
  ulong lu_class
  string ls_name
  string ls_disk
  string ls_ser
  string ls_flag
  string ls_day
  string ls_num
  string ls_ltime
  string ls_regflag
  string ls_regcode
  date ld_d1
  date ld_td
  integer tsh
  integer tshch
  integer check_result
  
  ls_right = f_encode(f_redreg("0"))
  ls_wrong = f_encode(f_redreg("1"))
  
  if ((ls_right <> "wright") or (ls_wrong <> "wrong")) then//检测软件是否被破坏,手工改过注册表
          return -400
  end if
  
  ls_regflag = f_redreg("3")   //错误标记
  
  if ls_regflag = "err" then
          ls_flag = f_encode("90")
          ls_day = f_encode("30")
          ls_disk = f_encode(f_getdisk())
          f_setreg("2",f_encode(f_genser()))
          f_setreg("3",ls_flag)
          f_setreg("4",f_encode("f7657lo"))
          f_setreg("5",ls_day)
          f_setreg("6",f_encode("fj;[57lo"))
          f_setreg("7",f_encode(string(today())))
          f_setreg("8",f_encode("fj57lo"))
          return 100
  end if
  
  ls_ser = f_encode(f_redreg("2"))
  ls_flag = f_encode(f_redreg("3")) //注册表中在HKEY_CURRENT_USER\Software\xsxt\xsxt_3下存放是否注册的标志
  ls_day = f_encode(f_redreg("5"))
  ls_ltime = f_encode(f_redreg("7"))
  ls_regcode = f_encode(f_redreg("9"))
  ld_d1 = date(ls_ltime)
  ld_td = today()
  tsh = daysafter(ld_d1,ld_td)  //安装爱期与当前爱期比较
  
  if tsh < 0 then
          return -100落后 //若小,说明改过爱期
  end if
  
  if ls_flag = "89" then  //89这个标记,代表已经注册,继续检测注册码是否合法
          check_result = f_checkregcode(ls_regcode)//调用f_checkregcode检查注册码合法性
  
          if check_result = 0 then
                  return 200   //注册
          else
                  return -200 //注册码不合法
          end if
  
  else
          tshch = integer(ls_day) - tsh//代表已过期
  
          if tshch <= 0 then
                  f_setreg("5","00")
                  f_setreg("7",f_encode(string(today())))
                  return -300
          else
                  ls_day = f_encode(uf_patchstr(string(tshch),2))
                  f_setreg("5",ls_day)
                  f_setreg("7",f_encode(string(today())))
                  return 300

  在上面的代码中,关键部分作为注释,现总结一下:
  对注册起作用的是f_checkregcode和f_getdisk。
  注册码算法为:
  1、注册码为16位长度的串,为大写。
  2、取出硬盘序列号后,若为8位16进制串,则不变,否则在前补0,拼成8位串。
  3、对所得的硬盘序列号串,按f_checkregcode中的明密文转换表,进行变换,变换的结果,分别记入注册表串的奇数位,即1,3,5,7,9,11,13,15的位置。
  4、注册码偶数位的字符任意,只要是明密文表中能找到可以了。我在注册机中指定为‘A’。

【经验总结】
  这次破解主要在笨鸟我先飞兄弟的基础上做的,他把PBKILLER反编译后的代码给了我,我只是阅读了PB的源码,PB脚本与
  BASIC语法类似,兄弟们如果破PB,可以参照BASIC语法来阅读源码。
  
  PBKILLER真的很强,反编译出来的代码可读性很好,呵呵。
