tcpnethaspsrv
tcpnethaspsrv is a network service used primarily to facilitate license management and copy protection for software utilizing the HASP (Hardware Against Software Piracy) dongle system developed by Aladdin Knowledge Systems. It allows software applications to communicate with hardware dongles over TCP/IP networks, enabling centralized licensing control and enforcement..
Port 475 is officially assigned to tcpnethaspsrv, part of the HASP licensing system from Aladdin Knowledge Systems (now SafeNet/Gemalto). This network license manager daemon enables software to authenticate licensing dongles over a TCP/IP connection, supporting centralized license administration instead of relying on direct hardware connections to each client machine.
The tcpnethaspsrv service listens on this port, handling requests from protected software clients that need to verify the presence of a valid HASP dongle before the application starts or during its operation. It transmits authentication and cryptographic challenge/response data between client software and the hardware dongle. This architecture streamlines the management of multiple licensed users while simplifying license deployment in corporate network environments.
Typically, tcpnethaspsrv runs on a dedicated license server reachable by all clients. The underlying protocol is proprietary and optimized for HASP communications over TCP. Because HASP integrates both hardware-level security and network remote validation, it remains a popular licensing solution where offline or static licensing is impractical.
