The name comes from the Russian-based group SolidSquad, a team of reverse engineers active in the 2000s and 2010s. They didn’t just release tools—they documented dongle protocols, published API hooks, and created one of the most robust emulation environments ever seen. Their goal? Preservation of abandonware and studying protection flaws. Whether you view them as heroes or villains depends on your stance on DRM.
Naturally, dongle vendors fought back. Newer HASP keys (SRM, Sentinel LDK) introduced encrypted communication, anti-debugging, and timer checks. MultiKey evolved too—community forks added support for HASP SRM, Sentinel HL, and even CodeMeter (Wibu-Systems). However, cloud-based licensing (always-on verification) has largely made dongle emulation obsolete for modern SaaS products. solidsquad multikey
