# How to XOR with Metasploit::Framework::Compiler
|
|
|
|
The Metasploit C compiler has built-in support for XOR encoding and decoding, which is implemented as the `xor.h` header.
|
|
|
|
# Code Example
|
|
|
|
```c
|
|
#include <Windows.h>
|
|
#include <String.h>
|
|
#include <xor.h>
|
|
|
|
int main(int args, char** argv) {
|
|
char* xorStr = "NNNN";
|
|
char xorKey = 0x0f;
|
|
LPVOID lpBuf = VirtualAlloc(NULL, sizeof(int) * strlen(xorStr), MEM_COMMIT, PAGE_EXECUTE_READWRITE);
|
|
memset(lpBuf, '\0', strlen(xorStr));
|
|
xor((char*) lpBuf, xorStr, xorKey, strlen(xorStr));
|
|
MessageBox(NULL, lpBuf, "Test", MB_OK);
|
|
return 0;
|
|
}
|
|
```
|

To compile, use [Metasploit::Framework::Compiler::Windows.compile_c](https://github.com/rapid7/metasploit-framework/wiki/How-to-use-Metasploit%3A%3AFramework%3A%3ACompiler%3A%3AWindows-to-compile-C-code) |
