Hello,CTF reverse

一看到是序列号判断，
立马拉进OD，
爆破法，
结果。。。。。
弹出success
FUCK
居然不输出结果，但由于OD中的跳转太乱了，不看了，拉进IDA，f5

int __cdecl main(int argc, const char **argv, const char **envp)
{
  signed int v3; // ebx
  char v4; // al
  int result; // eax
  int v6; // [esp+0h] [ebp-70h]
  int v7; // [esp+0h] [ebp-70h]
  char v8; // [esp+12h] [ebp-5Eh]
  char v9[20]; // [esp+14h] [ebp-5Ch]
  char v10; // [esp+28h] [ebp-48h]
  __int16 v11; // [esp+48h] [ebp-28h]
  char v12; // [esp+4Ah] [ebp-26h]
  char v13; // [esp+4Ch] [ebp-24h]
 
  strcpy(&v13, "437261636b4d654a757374466f7246756e");
  while ( 1 )
  {
    memset(&v10, 0, 0x20u);
    v11 = 0;
    v12 = 0;
    sub_40134B(aPleaseInputYou, v6);
    scanf(aS, v9);
    if ( strlen(v9) > 0x11 )
      break;
    v3 = 0;
    do
    {
      v4 = v9[v3];
      if ( !v4 )
        break;
      sprintf(&v8, asc_408044, v4);
      strcat(&v10, &v8);
      ++v3;
    }
    while ( v3 < 17 );
    if ( !strcmp(&v10, &v13) )
      sub_40134B(aSuccess, v7);
    else
      sub_40134B(aWrong, v7);
  }
  sub_40134B(aWrong, v7);
  result = stru_408090._cnt-- - 1;
  if ( stru_408090._cnt < 0 )
    return _filbuf(&stru_408090);
  ++stru_408090._ptr;
  return result;
}

注意到：

strcpy(&v13, "437261636b4d654a757374466f7246756e");
 

 
strcat(&v10, &v8);
 
while ( v3 < 17 );
    if ( !strcmp(&v10, &v13) )
      sub_40134B(aSuccess, v7);
 

要看到是0x，
十六进制，
又看到数组最多20个，
而后面数组35个，
又猜想结果是英文串串，
那每两个当成一个十六进制吧！！！

py脚本：
a = [0x43,0x72,0x61,0x63,0x6b,0x4d,0x65,0x4a,0x75,0x73,0x74,0x46,0x6f,0x72,0x46,0x75,0x6e]
c = “”
for x in a:
c += chr(x)
