The krackme_1.out file was decompiled in IDA Pro and only the code necessary for FLAG was programmed in C.
```c#include <stdio.h>#include <string.h>
int main(){  unsigned int i, j;  short a[10], b[10];  char c[32] ="Oh My God ! What is that ?";  char d[48] = "You don't have access to KrackMe 1.0 !";  char e[72] = "Did you know, Bangladesh has the longest natural beach?...";  char s[36];  strcpy((char *)a, "mer`]MtGe");  strcpy((char *)&a[5], "aUG9UeDoU");  strcpy((char *)b, "(G~Ty_G{(");  strcpy((char *)&b[5], "v}QlOto|s");  for ( i = 0; i < 9; ++i ){    for(j=0; j<=255; j++){        if ( *((unsigned char *)a + i) == ((unsigned char)38 ^ (unsigned char)j) ){            s[i]=j;        }        if ( *((unsigned char * )&a[5] + i) == ((unsigned char)10 ^ (unsigned char)j) ){            s[i+9]=j;        }        if ( *((unsigned char *)b + i) == ((unsigned char)24 ^ (unsigned char)j) ){            s[i+18]=j;        }        if ( *((unsigned char *)&b[5] + i) == ((unsigned char)14 ^ (unsigned char)j) ){            s[i+27]=j;        }    }  }  for(i=0; i<=35; i++){    printf("%c",s[i]);  }}```
