Legitimate software uses dongles—physical USB keys that contain encrypted data. When you run the software, it checks for the dongle. Multikey intercepts these check calls (via API hooks and device drivers) and pretends to be the real dongle. It reads a "dump" file (e.g., .dng , .hasp , .reg ) that contains the exact data from a genuine dongle and serves that data to the software.
