那么把regkey改为:6789543267895432678954326789543267eo5432应该可以了吧。
但是运行完还是未注册。这时变为
:0045FBF4 3A4622 cmp al, byte ptr [esi+22] //比较第35位（比较是否为 "M" )
:0045FBF7 750F jne 0045FC08 // 不相等则跳至末注册

:0045FBFF 3A4623 cmp al, byte ptr [esi+23] //比较第36位（比较是否为"u" )
:0045FC02 7504 jne 0045FC08 //不相等则跳至末注册
:0045FC04 C645FF01 mov [ebp-01], 01 //程序走到这里就可以注册成功了
原来是bl中注册码和为指引，提取字串“HACKERYouMUSTDie”(哈哈，我好怕怕啊，难道有下什么套？)的字母，与35位及36位的注册码进行比较。但其实也很简单，令注册码的和仍为7F且
35，36位为e,o就可注册成功。如下：
regname:killer
regkey: 6789543267895432678954326789543267eoMP5432
就可显示注册给killer了。
哈哈 so easy!!
但运行对文件加密，却跳出提示框“你的文件超过4kb,请注册你的软件”。呜呜，无法使用。是不是我高兴的太早了？是不是我MUST Die?
Can u help me ?
