The SafeNet Inc HASP Key is a hardware-based copy protection and licensing system, typically used by software vendors to protect their applications from piracy and unauthorized use. The HASP Key (Hardware Against Software Piracy) is a USB device that acts as a dongle, storing software licensing information. It is often required for running certain commercial software applications that use this form of licensing.

The HASP Key Windows driver is the software that allows your Windows operating system to communicate with the HASP dongle plugged into your USB port, enabling the software to read the license stored on the dongle. Without this driver, your computer will not recognize the HASP key, and any software dependent on it will not work.
