The Concept

• Multikey refers to a driver suite (originally developed by a Russian firm "E.T.D." and later adapted by the community) that can emulate multiple types of dongles: HASP4, HASP HL, Sentinel SuperPro, Guardant, and others.
• Virtual USB means the driver creates a software-simulated USB controller inside Windows. When an application queries for a dongle, the virtual driver responds as if a physical dongle were plugged in, using a "dump" file (.dmp or .rg), which contains the original dongle’s ID and encrypted data.
