<h1>Step 2.1: Creating a new protected application</h1>
|
|
|
|
<p>At the first stage we made several simple apps to test the API of the licensing system. Now, on the second stage we'll create just one application. It will also be a console app with the <strong>foo()</strong> function working only in the registered version. Here is the code of our test application:</p>
|
|
<pre class="code">#include <windows.h>
|
|
#include <stdio.h>
|
|
#include "VMProtectSDK.h"
|
|
|
|
#define PRINT_HELPER(state, flag) if (state & flag) printf("%s ", #flag)
|
|
void print_state(INT state)
|
|
{
|
|
if (state == 0)
|
|
{
|
|
printf("state = 0\n");
|
|
return;
|
|
}
|
|
|
|
printf("state = ");
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_CORRUPTED);
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_INVALID);
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_BLACKLISTED);
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_DATE_EXPIRED);
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_RUNNING_TIME_OVER);
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_BAD_HWID);
|
|
PRINT_HELPER(state, SERIAL_STATE_FLAG_MAX_BUILD_EXPIRED);
|
|
printf("\n");
|
|
}
|
|
|
|
char *read_serial(const char *fname)
|
|
{
|
|
FILE *f;
|
|
if (0 != fopen_s(&f, fname, "rb")) return NULL;
|
|
fseek(f, 0, SEEK_END);
|
|
int s = ftell(f);
|
|
fseek(f, 0, SEEK_SET);
|
|
char *buf = new char[s + 1];
|
|
fread(buf, s, 1, f);
|
|
buf[s] = 0;
|
|
fclose(f);
|
|
return buf;
|
|
}
|
|
|
|
// The foo() method is very short, but we need it to be an individual function
|
|
// so we asked the compiler to not compile it inline
|
|
__declspec(noinline) void foo()
|
|
{
|
|
printf("I'm foo!\n");
|
|
}
|
|
|
|
int main(int argc, char **argv)
|
|
{
|
|
char *serial = read_serial("serial.txt");
|
|
int res = VMProtectSetSerialNumber(serial);
|
|
delete [] serial;
|
|
if (res)
|
|
{
|
|
printf("serial number is bad\n");
|
|
print_state(res);
|
|
return 0;
|
|
}
|
|
printf("serial number is correct, calling foo()\n");
|
|
foo();
|
|
printf("done\n");
|
|
return 0;
|
|
}
|
|
</pre>
|
|
|
|
<p>Compile the program without the debug information, but in the linker settings we enable creating of the MAP-file - we will need it to work with VMProtect. After we run the program, we should see the following text:</p>
|
|
<pre class="code">serial number is bad
|
|
state = SERIAL_STATE_FLAG_INVALID
|
|
</pre>
|
|
|
|
<p>Currently, the licensing system still works in the test mode, because the file wasn't processed by VMProtect and doesn't contain a licensing module in it. On the <a href=
|
|
"step22_vmp.htm">next step</a> we will create a VMProtect project and will try to protect our application.</p><br />
