Syskey
Syskey is a simple NtUserGetAsyncKeyState syscall wrapper. This implementation was done in a way to avoid both imports and direct calling of GetAsyncKeyState for obscurity and security.
Prodecure:
Dynamically finds and saves the syscall ID of NtUserGetAsyncKeyState
Calls the syscall ID using the VK code provided
Returns as expected
Example usage:
if (nt::GetKey(VK_F1) & 0x8000)
printf("F1 just got called!\n");
