<h1>Step 1.1: Creating a protected application</h1>
|
|
|
|
<p>The first step is to create an application. This would be a simple app without any user interface and with no serious capabilities. Our goal is to pass a serial number to the licensing system and receive its answer..</p>
|
|
<pre class="code">#include <windows.h>
|
|
#include <stdio.h>
|
|
|
|
bool is_registered(const char *serial)
|
|
{
|
|
return serial && serial[0] == 'X';
|
|
}
|
|
|
|
int main(int argc, char **argv)
|
|
{
|
|
char *serial = "Xserialnumber"; // we set the serial number directly in the code, for simplicity
|
|
if (!is_registered(serial))
|
|
{
|
|
printf("please register!\n");
|
|
return 0;
|
|
}
|
|
printf("We are registered.\n");
|
|
return 0;
|
|
}
|
|
</pre>
|
|
|
|
<p>The program uses a very simple way to check the serial number. The <strong>is_registered()</strong> function compares the first symbol of the serial number with 'X' and thinks the number is correct if this they match. For an incorrect serial number, a registration message is displayed, while if a user enter the correct key, "We are registered." is shown instead</p>
|
|
|
|
<p>The <a href="step12_code.htm">next step</a> is to add the code to check the serial number using the licensing system of
|
|
VMProtect.</p><br />
