## How to decode Base64 with Metasploit::Framework::Compiler
|
|
|
|
The Metasploit C compiler has built-in support for Base64 encoding and decoding, which is implemented as `base64.h`.
|
|
|
|
# Code Example
|
|
|
|
```c
|
|
#include <Windows.h>
|
|
#include <String.h>
|
|
#include <base64.h>
|
|
|
|
// "Hello World" encoded by Rex::Text.encode_base64()
|
|
#define BASE64STR "aGVsbG8gd29ybGQ="
|
|
|
|
int main() {
|
|
int base64StrLen = strlen(BASE64STR);
|
|
LPVOID lpBuf = VirtualAlloc(NULL, sizeof(int) * base64StrLen, MEM_COMMIT, PAGE_EXECUTE_READWRITE);
|
|
memset(lpBuf, '\0', base64StrLen);
|
|
base64decode(lpBuf, BASE64STR, base64StrLen);
|
|
MessageBox(NULL, (char*) lpBuf, "Base64 Test", MB_OK);
|
|
return 0;
|
|
}
|
|
```
