Guardant Stealth II
Guardant Stealth II is a mainstream dongle with basic functionality. It is used for software protection based on its symmetric encryption functionality. Now Stealth II is being produced on the fast 32-bit Cortex-M3 microcontroller with 256 bytes of non-volatile memory.
Guardant Stealth II is a widely used dongle for software protection against piracy and unauthorized use. This dongle together with Guardant Automatic protection provides a cost-effective approach for Win32 and .NET applications defense. After all Guardant API allows developer to enhance protection quality and create his own unique mechanisms.
The dongle is built on a high-speed 32-bit RISC processor. It has a number of cryptographic algorithms including tailor-made GSII64 (128 or 256 bit key) for symmetric encryption. There is 256 bytes of non-volatile memory to store cryptographic keys, to which protected applications are bond. All the memory has hardware protection against invasion analysis.
Stealth II allows developer to protect local Win32 or .NET applications so that the only computer where the dongle is plugged will run the protected application for this dongle. There is also a network edition dongle called Guardant Net II. It enables you to distribute more than one license a dongle and further licensing within a local network for your clients.
